Digestive health usually gets attention only when something goes wrong. But the truth is, good digestive health is built quietly, through small daily habits repeated consistently over time.

As we recognize World Digestive Health Day this month (May 29), it’s worth stepping back from the trends, supplements, and internet “gut hacks” to focus on what actually works.

Omar Khokhar, MD, a gastroenterologist at OSF HealthCare, says your digestive system is remarkably resilient and if you support it well, it often returns the favor for decades.

One way to avoid digestive issues and inflammation, Dr. Khokhar says, is to avoid eating convenience or ultra processed food.

Avoid ultra processed food

“So for me, ultra processed food is something that comes out of a wrapper, out of a box, out of a can. It’s something that was made in a factory 300 miles away, two months ago that you now see in your local grocery store. So, there is a convenience factor, but we're starting to see that we're paying for that convenience because those foods are difficult to digest and they can result in inflammatory changes to your gut.” 

Dr. Khokhar notes that while genetics can influence the risk of conditions such as celiac disease, inflammatory bowel disease and digestive cancers, daily habits still play a major role in long-term gut health. He says research now shows that when the lining of your gut is disrupted, it can have negative impacts.

“So, the more that we don't do on a daily basis, whether it's fiber, having good bowel movement, making sure we keep a good microbiome, that may result over time in disruption of the mucosal or lining of your stomach and your intestine,” he says.

When that happens, Dr. Khokhar points out, the body will absorb things it shouldn’t, and it won’t be getting what nutrients it should be getting.

If you can only do two things to improve your gut health, Dr. Khokhar says adopt these two habits.

“Flush the pipes. Make sure you drink enough water. Make sure you get enough fiber – whether that’s in diet, whether that’s a supplement, it really doesn’t matter to me at this point. If you get enough fiber and you flush your pipes and you’re evacuating your G.I. tract, it’s going to help remove the waste product.” He adds, “Once you remove the waste product from the colon, everything else can flow down.” 

For fiber, Dr. Khokhar says focus on foods found around the perimeter of the grocery store, including fruits, vegetables, and lean proteins.

Walk after meals

One other good habit to consider – taking a walk after meals. Dr. Khokhar advises even short walks can improve digestion and reduce discomfort.

“After you eat, go for an eight-to-10-minute walk. The activity helps everything, literally from a gravity point of view, a physical point of view, a gas expulsion point of view.” He adds, “It almost helps you reset and recalibrate before you inevitably in our society – we sit back down.” 

A final point from Dr. Khokhar – do not to ignore persistent abdominal pain or major changes in bowel habits. He warns those symptoms can sometimes signal more serious conditions, including colon cancer.

Dr. Khokhar is a gastroenterologist practicing at OSF HealthCare in Bloomington, Illinois.

B-roll-World Digestive Health Day

A new study is challenging long-held assumptions about coffee’s effects on digestive health, suggesting the popular beverage could offer benefits for both the gut and the brain.

The research, published in Nature Communications, examined 62 participants, half of whom were regular coffee drinkers, to explore how coffee consumption influences the gut microbiome and mental well-being. Using psychological assessments alongside dietary tracking and biological samples, researchers found that individuals who drank coffee, whether caffeinated or decaffeinated, reported lower levels of stress, depression and impulsivity.

The findings point to a growing scientific consensus: coffee is more than just a caffeine delivery system. According to the study’s authors, it acts as a complex dietary component that interacts with gut bacteria, metabolism and even emotional health.

Researchers also observed higher levels of beneficial bacteria among coffee drinkers, including strains linked to protection against harmful microbes and inflammation. Caffeinated coffee, in particular, was associated with reduced anxiety, improved attention and lower markers of inflammation.

Still, OSF HealthCare gastroenterologist Omar Khokhar, MD, cautions against drawing sweeping conclusions.

Kinds of coffee could make a difference

Dr. Khokhar points out it’s a small study that supports a hypothesis, but it’s not definitive proof that coffee will improve gut health or mood.

“There are so many different kinds of coffee. There’s Turkish coffee, there’s South American coffee, there’s Dunkin Donuts coffee, there’s Folger’s and Sanka for some of the people watching this on Facebook.” He points out, “It just comes down to each person and their own individual microbiome and how it responds to whatever particular type of coffee they’re ingesting.” 

Instead, Dr. Khokhar believes the study contributes to a broader shift in how scientists understand nutrition. Rather than labeling foods as strictly “good” or “bad,” researchers are increasingly focusing on individual responses, particularly how a person’s unique gut microbiome influences their reaction to what they consume.

Coffee itself is chemically complex, containing compounds such as polyphenols, which Dr. Khokhar says might act to feed beneficial gut bacteria.

“Now let’s suppose you’re at baseline and you have overall good gut hygiene and function; coffee could potentially be a good thing. It could be a prebiotic of sorts, that could potentially support your microbiome in that case.” 

This could help explain the observed microbiome changes in coffee drinkers.

However, those same compounds can have downsides. Coffee is known to relax the lower esophageal sphincter, potentially triggering heartburn, and Dr. Khokhar stresses coffee exacerbates symptoms in people with conditions such as irritable bowel syndrome.

The study did not differentiate between types of coffee, such as espresso versus brewed coffee, highlighting another limitation and an area for future research.

More research is needed

Dr. Khokhar says the study shows a link but not a direct cause and he thinks more controlled studies are needed to determine how specific varieties and preparation methods influence health outcomes.

“What I would like to see personally is if you controlled for what specific coffee a group of volunteers ingested and then either through blood or stool, looking at their exact gut microbiome diversification or pattern to see if that improved or how that changed from a robustness and a diversity point of view,” he says. “That would be more objective.” 

The research also raises intriguing questions about the gut-brain connection. Scientists now understand that the gut microbiome plays a role in producing neurotransmitters like serotonin, which can influence mood, sleep and behavior.

Whether coffee can enhance mood indirectly by improving gut health remains a hypothesis but an appealing one for millions of daily coffee drinkers.

For now, the takeaway is about embracing moderation and self-awareness. As Dr. Khokhar puts it bluntly, “If it makes you feel bad, don’t do it.” But he says if people can tolerate coffee well, in moderation, it might not be as harmful as once thought and could even be helpful, but more research is needed to prove that.

If you have questions about what's best for their health, talk to your primary care provider.

• Lordosis: This refers to the normal, c-shaped curvature of the lower back.
   
• Kyphosis: This is the normal curvature of the upper back.
  
  In each case, the term itself doesn’t indicate a deformity. But the curvature can become abnormal, prompting a spine physician to take a look and possibly recommend lifestyle changes.

Bonafide spine disorders include:

• Scoliosis: This curvature of the spine brings back pain “from muscles having to compensate to hold the spine and body in the right position,” Dr. Syed says. Sometimes, nerves get pinched, leading to chest, abdomen or leg pain. Severe cases could bring paralysis. Or, a lung could get pinched, leading to impaired breathing. This is called thoracic insufficiency syndrome.
  
  Genetics, nutrition, muscle imbalance and lifestyle can all contribute to getting scoliosis. Your spine can also naturally worsen with age.
  
  “The discs start to thin. The spine starts to tilt. That puts more strain on the joints. They tend to overgrow, twist and change in size. That creates a domino effect. You get this spine that’s really twisted,” Dr. Syed explains.
  
  Dr. Syed adds that most scoliosis cases can be addressed without surgery. The person can change their lifestyle, notably getting on an exercise plan that strengthens the muscles that support the spine. In severe cases, a surgeon would put screws, rods or plates into your spine or make cuts in the bones.
  
  “It pulls the spine into the correct space, frees up the nerves from the pressure on them and gets the spine to heal in that position,” Dr. Syed says.

• Ankylosing spondylitis (AS): Dr. Syed says this is an inflammatory condition in various joints due to the body’s immune system not working properly.
  
  “Normally, your spine is made up of a bunch of repeating segments. They move relative to each other. That’s how you bend and twist,” Dr. Syed says. “In AS, the joints start to become solid bone because of inflammation. That leads to very stiff, brittle painful bones. People are predisposed to fractures with minor falls. Those people we typically see, unfortunately, in trauma settings. They have brittle, stiff spine that doesn’t have any bend or give. They have a fall, and the spine breaks.”
  
  Dr. Syed says a rheumatologist could put an AS patient on an immune-modifying medicine to prevent inflammation.

Prevention

Keeping a healthy spine comes down to “fundamental good behavior,” Dr. Syed says.

• Avoid activities that could injure the spine. That could be everyday things like heavy lifting or career choices like a contact sport.
   
• Maintain a healthy weight through a healthy diet and active lifestyle.
  
  “You don’t want to be too skinny or too big,” Dr. Syed suggests. “That puts either too much strain [when you’re overweight] or not enough muscle to support the spine [when you’re underweight].
  
  “It’s like Goldilocks,” Dr. Syed adds, referring to the “not too hot, not too cold” fairytale. “You want to work out but not too intensely that you’re crossing over into injury.”
  
  Walks or light jogs could be the things for you, he says.
   
• Avoid smoking.

A shin-termission: Navigating lower leg pain

It’s something Michael Daley, MD, sees in the emergency department often and especially this time of year: chronic obstructive pulmonary disease, or COPD.

Dr. Daley, who provides care at OSF HealthCare, says while there’s no cure for COPD, medicine has come a long way to improve your quality of life with the disease.

COPD basics

Dr. Daley says more than 300 million people suffer from COPD, and it’s is the fourth leading cause of death worldwide.

“It’s a destruction of the lung tissue in the airways. A lot of inflammation and destruction over time that causes the condition to manifest itself in people in different ways,” Dr. Daley says.

Those ways include shortness of breath, chest tightness, coughing and fever. Dr. Daley points out that those symptoms overlap with a similar disease: asthma. But each has their differences, too.

“Asthma is seen as a disease of the young. People with asthma usually have that diagnosis at a much earlier age than someone with COPD,” Dr. Daley explains. “The textbooks will tell you that you typically see COPD in the sixth decade of life. So, people in their 60s, 70s and 80s.”

Treatment

Dr. Daley says many of the people he sees know they are having a COPD flare up.

“We immediately get them into a room. We put them on oxygen. We initiate various therapies that have been shown throughout the years to work well,” he says. “We’d give them steroids, antibiotics and inhalers over the course of one to three hours. We observe them and watch them improve.”

Though Dr. Daley says it’s not frequent, people can come to the hospital with a severe COPD flare up.

“They’re not moving any air at all. They’re in extreme distress,” he says.

That person would go on a ventilator to, first and foremost, save their life, but also to get them breathing more easily again. Dr. Daley says after a few days on a ventilator, health care providers would then tap into other treatments.

Long-term, a person may go on a nebulizer. It’s a machine that delivers a mist of medicine inside your body through a mouthpiece or mask. The medicine helps your airways to relax and expand, allowing you to breathe easier. This is different from an oxygen tank.

Pulmonary rehabilitation in a hospital or clinic is also a common part of treatment. Like lifting weights to build up muscle, pulmonary rehab involves exercises to work your way back to as normal breathing as possible.

“Often they’ll do what’s called chest physiotherapy. They wear a percussion vest. That helps them cough up a lot of mucus and phlegm inside their lungs that’s preventing them from breathing [well],” Dr. Daley says. “They also do a lot of breathing exercises that will help their airways expand. That leads to a better quality of life.”

Prevention

Dr. Daley says smoking tobacco is a leading cause of COPD, especially in the United States. Worldwide, air pollution is also a trigger, whether that’s outdoor smog or indoor dust and dander.

“We’re actually seeing a much younger population presenting with COPD. People in their 30s and 40s. Just because of very heavy tobacco usage,” Dr. Daley says.

So if you’re a smoker, make a plan to stop. If you live in a smoggy area, avoid prolonged exposure. Consider wearing a mask when outside. And keep your home clean and well-ventilated.

Dr. Daley adds that respiratory viruses like influenza can make COPD worse, leading to an uptick of cases in the winter. So, take basic hygiene steps to avoid those seasonal illnesses: wash your hands, cough and sneeze into your elbow, stay home when sick and be up to date on vaccinations.

With temperatures cooling, Awad Alyami, MD, an OSF HealthCare pediatrician, says we’re approaching the peak season for sore throats. Many cases have time-tested treatments, but some can have serious complications.

Dr. Alyami says a sore throat is an infection that causes inflammation in your throat. They’re annoying and painful, bringing symptoms like difficulty swallowing or talking and swelling of glands and tonsils. Causes can include tonsil stones, heartburn and allergies. But most commonly, causes break down into two groups: viral and bacterial.

Viral infections

Dr. Alyami says many viruses can cause sore throats – the common cold, influenza, coronavirus and others. Dr. Alyami says if your sore throat comes with coughing or a runny nose, that’s a sign it’s a viral infection. You can start treatment at home with over-the-counter medicine like Tylenol and ibuprofen. You can also gargle salt water and, generally, stay hydrated. Water is good for all ages, and Pedialyte can help hydrate kids.

If your symptoms include fever and neck swelling, it’s a more serious situation. You should see a health care provider.

Bacterial infections

The main bacterial infection that causes sore throats is group A streptococcus (commonly known as strep or strep throat). Strep throat may bring the hallmark sore throat symptoms, but you should also watch for fever and white patches toward the back of your mouth.

“This is a bacterial infection that’s common in kids,” Dr. Alyami says of strep throat.  “About 30% of sore throats are strep, and about 70% are viral. It’s a big deal. We need to treat to prevent complications.”

The most common complication is dehydration, Dr. Alyami says.

“The sore throat is so bad, the child doesn’t want to eat or drink,” he explains.

Other times, untreated strep throat can lead to abscesses, or pus pockets.

“If that abscess gets big enough, it can go toward other structures in the body that are very important. That infection can spread and progress very quickly,” Dr. Alyami says. Life-threatening conditions like difficulty breathing can result.

Dr. Alyami says providers can diagnose strep throat with a throat swab. They treat strep throat with 10 days of antibiotic medication, either injected or taken orally. He says most kids will take the medicine orally unless that’s troublesome. For example, some kids have a tough time swallowing pills due to throat pain.

Prevention

It’s advice you’ve heard before, but it’s worth repeating. Dr. Alyami says good hand hygiene goes a long way to preventing sore throats. Wash your hands thoroughly, and keep them away from your face.

Early detection is also key.

“If the child is sick, especially with symptoms that could be strep, it’s better to get them to a health care professional early,” Dr. Alyami implores. “They can get checked and isolated for 12 to 24 hours before they start antibiotics.

“If you’re sure about what they have, it’s better to just bring them in and get them checked,” he adds. Or, a virtual visit is an option.

Another “bronch” to know
Allergic rhinitis is a year round concern

Are you the type of person who can’t wait to kickstart your day with that piping-hot cup of coffee in the morning? If so, there’s good news for you.

According to a recent study published in the European Heart Journal, one perk of morning coffee is it’s healthier for you than any other part of the day.

Early risers – coffee connoisseurs who pour their first cup of java between 4 a.m. and noon – have a 16% lower chance of dying from any cause compared to non-coffee drinkers.

According to the study, coffee drinkers also had a 31% lower risk of dying from heart disease compared to non-coffee drinkers.

“The study identified that one of the aspects of coffee lowers inflammation, and we have more inflammation in the morning. And so that's why the benefit was shown in this study,” says Nancy Dagefoerde, a nurse practitioner with OSF HealthCare Cardiovascular Institute. “I do agree that that's a good benefit of drinking coffee in the morning.”

The findings were the result of work done by researchers from Tulane University who analyzed dietary and health data from 40,000 adults between 1999 and 2018. The research team studied two groups – morning-only coffee drinkers and all-day coffee drinkers.

Researchers focused on patterns of drinking coffee throughout the day rather than the amount of coffee consumed. Dagefoerde recommends drinking no more than two or three cups a day.

Another important aspect of coffee is how it’s made. Past studies have shown evidence of a link between coffee brewing methods, heart attacks and longevity. For example, unfiltered coffee that’s boiled contains higher amounts of chemicals that can raise triglyceride levels and low density lipoprotein (LDL) cholesterol levels.

“Filtered coffee is more beneficial. Boiled can actually be more harmful. There are many compounds in coffee that are beneficial to health in general,” says Dagefoerde. 

But a cup of brew isn’t everything when it comes to heart health. Dagefoerde says there are other things you should be doing including exercising, treating your blood pressure and cholesterol.

“Coffee can lower inflammation, increase your metabolism and decrease the absorption of fats,” she adds. “But you definitely want to work on all your risk factors, not just drinking coffee.”

It’s better to drink black coffee, but if you take it with sugar or cream, make sure you are using the ones that are as healthy as possible such as unsweetened almond milk, raw honey or cinnamon. Cream adds 50 calories and three grams of saturated fat per tablespoon. And a teaspoon of sugar contains 16 calories, which adds up quickly.

Dagefoerde says while the studies are encouraging, it doesn’t mean you should race to your local coffee shop and start guzzling mugs of java purely for the health benefits.

“Coffee is popular in our nation, and in many countries. And the social aspect is nice too,” she says. “But don’t overdo it, and just know the risks if you do.”

For mom

Anderson says it’s no problem for pregnant women to have onions in their diet.

“They are very rich in antioxidants. That’s something we don’t get a lot of. They’re really high in vitamin C,” Anderson says. “They have fiber, magnesium and potassium. Fiber and magnesium help with digestion, and magnesium helps with cramps. Potassium is really good for blood circulation and blood pressure.”

But, there are the usual precautions. When adding raw onions to a meal (a salad, for example), wash them to remove any bacteria. And don’t overindulge. For example, don’t have a greasy, processed cheeseburger as an excuse to get your daily onion intake.

“Onions are a high FODMAP food, which means there are carbohydrates that are harder for some people to digest,” Anderson adds, noting that a woman’s digestive system changes a lot when carrying a baby. “So if you have a sensitive digestive system, onions could cause bloating. If you have irritable bowel syndrome, onions can make that flare up. Cooking onions helps break down some of those carbohydrates and aids digestion.”

For baby

Infants should consume breastmilk or formula exclusively for at least the first six months, Anderson reminds. But after that, introducing onions is like introducing any other food: Slow and steady wins the race.

One option: Sauté some onions to soften them, cut the food into small pieces to prevent choking then work the onions into the store-bought baby food.

“Make it easy for baby to chew. They’ve never had to do that before,” Anderson points out. “It’s good to let them learn how to chew, but we need to make sure the foods are easy to chew.

“Onions help develop a baby’s palette,” Anderson adds of the benefits of the vegetable. “Experts are finding that introducing strong flavors like that can prevent picky eating in the future.”

Precautions and warning signs to know: If the baby is extra fussy or gassy or has an allergic reaction like a rash or diarrhea, take the onions out of the diet and see if that improves things. See a health care provider if symptoms don’t improve.

Myth vs. fact

Do a web search for “babies and onions,” and you’ll find a lot of claims.

• Can onions help with colic, a condition where a healthy baby cries for a long time? Not so fast, Anderson says. In fact, onion-induced gassiness could make the baby even more fussy.
   
• Some say putting an onion in my baby’s crib or sock or giving them onion water can help with baby’s health. 
  
  “It’s supposed to draw out toxins,” Anderson says, repeating what she calls an “old wives’ tale.”
  
  But, Anderson says science doesn’t back the claims up. In fact, onions can irritate a child’s skin and eyes.
   
• Can eating onions help with teething, when the baby’s teeth emerge? There’s actually some truth to this one, Anderson says. To try it, skip other types and focus on green onions. Let the food cool in the refrigerator before giving it to the little one.
  
  “It’s teaching them to bring things to their mouth and chew. It’s a food that’s cool and not super hard. As they chew, it will break down. But it’s not going to disintegrate in the mouth,” Anderson says.
  
  All this can help with pain and inflammation, Anderson says. Just watch your youngster at all times while chewing.

Infant nutrition misconceptions
The first few weeks
Back to work
Chow down, new moms!

Freddie Freeman has plenty to be grateful for this holiday season. Not only did his Los Angeles Dodgers win the World Series in October, but the first baseman was named the series most valuable player.

But the best news for Freeman and his wife is that their young son is recovering after a scary bout of Guillain-Barré (pronounced Ghee-yan Bah-ray) Syndrome (GBS).

“Guillain-Barré Syndrome is an illness that we see often in adults, but we can see it in children as well,” says Asma Khan, DO, a pediatrician with OSF HealthCare. “It's an inflammation of the body. It's like an autoimmune disease but it's an inflammation where the body attacks its nerve cells.”

While experts aren’t sure of the exact cause of GBS, many people with Guillain-Barré exhibit early symptoms of an infection before a diagnosis is found. Freeman’s three-year-old son, Max, first started experiencing symptoms in July when he developed a viral infection. When Max was unable to stand or walk without being in pain, his parents rushed him to the hospital.

“Usually there's an illness about a few weeks prior to the onset of Guillain-Barré, within four to six weeks prior, and it's either a GI infection or upper respiratory infection,” says Dr. Khan.

Symptoms usually happen suddenly, can affect both sides of your body and start in the feet and legs. “We see signs of weakness,” says Dr. Khan. “We see some nerve issues where they have numbness, tingling, and weakness of the muscles progresses from your lower extremities, from your legs all the way up, and it can even reach your eyes, your lungs. So, it's progressive.”

While it’s rare, anyone can get GBS, but it’s more common in adults and especially in males. But Dr. Khan has seen a few cases in her pediatric practice.

“We notice the child having leg pain and refusing to walk or having an abnormal gait,” she says. “That's usually your triggering factor that you notice first, and then, upon evaluation, you notice weakness in the lower extremities, and then the reflexes are diminished or absent.”

The most severe problem is trouble breathing. Dr. Khan explains that as muscles and the chest wall get weaker, respiratory failure can occur. That’s the reason hospitalization is so important.

“We want to make sure they're eating okay,” she adds. “So as the weakness progresses, is it affecting their ability to swallow or choking? Do we need to give them a feeding tube? Do we need to give them fluids? And then the big thing that we need to really watch is respiratory status.”

Treatment includes plasma exchange, which filters out the antibodies in the plasma that are attacking the nerves. Another treatment, intravenous immunoglobulin therapy (IVIG), involves IV injections of immunoglobulins which are proteins that the immune system makes. IVIG can reduce the immune system’s attack on the nerves.

Physical, occupational and speech therapy may also be required, depending on the severity of the symptoms.

Dr. Khan says most people completely recover from Guillain-Barré Syndrome, but it can take six to 12 months, or longer. However, some people may experience lingering effects including weakness and fatigue.

Freeman has posted on his social media accounts that Max is back home and recovering. Still, the young boy has a long road ahead to regain his strength and learn to walk again.

You may have heard that tea is good for you, but when walking through the grocery aisle and being confronted by a barrage of options, it can be hard to choose.

Ashley Simper, the manager of dietetic services with OSF HealthCare, has done the research and has some helpful guidance.

To start, it’s best to understand the different kinds of teas and where they come from. Simper says black, white, oolong and green tea all come from the Camellia sinensis plant. Herbal teas come from root, stems and flowers of various plants, and they all have different benefits.

What’s the overall healthiest tea?

Overall, Simper says green tea shines above the rest. But diving into the specific benefits of each tea can help people choose what’s right for them.

“Consuming three or more cups of green tea a day leads to the most health benefits when it comes to cardiovascular disease, cancer and the overall risk of mortality,” Simper says. “The research is a little stronger when it comes to promoting heart health. The consumption of three to five cups of green tea a day has also been shown to lower blood pressure, stroke risk, and LDL (bad cholesterol),” Simper says.

Consuming three to five cups of green tea or black tea has also been shown to lower the risk of developing diabetes.

In 2022, a large study in the Annals of Internal Medicine showed that drinking black tea resulted in a modest reduction of overall death. A research team from the National Institutes of Health’s (NIH) National Cancer Institute (NCI) investigated roughly half a million adults, ages 40-60, in the United Kingdom (UK), who enrolled in the UK Biobank study between 2006-2010. The researchers followed participants until 2020 and found a 9-13% lower risk of death among people who drank at least two cups of tea per day than non-tea drinkers.

What makes tea so healthy?

“The compound in tea that leads to these health benefits is polyphenols. Polyphenols are a type of antioxidant, and antioxidants are linked to decreased inflammation and reduced risk of chronic disease,” Simper says. “The highest antioxidant compounds are in the green tea, followed by the oolong, black and then white teas.”

She adds that green tea and white tea contain an amino acid called L-theanine. Amino acids are the “building blocks” of protein, Simper adds.

“L-theanine has been linked to decreased anxiety, improved sleep and boosting mental clarity,” Simper says.

Cancer: Mixed reviews, additional safety tips

“When it comes to cancer, the research is conflicting. People who drank higher amounts of green tea had a decreased risk of liver, ovarian, lung and breast cancers. But it is important to keep in mind, that if you’re drinking really hot tea, you have a higher risk of esophageal and gastric cancers,” Simper says.

To avoid the tea being scalding hot, Simper recommends allowing the just-boiled water to cool down for an appropriate amount of time before taking a sip.

Tea’s impact on the flu

“In lab and animal studies, they have found an antiviral effect with the consumption of green tea. In Japan, they did a study with kids that showed anywhere from one to five cups of green tea a day lowered the risk of flu,” Simper says. “There was also a study where they gargled green tea in a bottle, green tea extract or black tea extract, and there was a 30% decreased risk of flu.”

How to prepare your tea

As Simper mentioned, scalding hot tea can come with its own risks, more than just burning your mouth. But there are other ways, she says, to make sure you’re receiving the most benefit from drinking tea.

“They recommend boiling your own water and steeping it yourself instead of putting the water in the microwave to heat it up. They found you lose some health benefits if you microwave the water in your tea. Fresh is best, steep your own, and boil your own water. But let it cool down to a comfortable temperature before you consume it. “Freshly brewed tea with minimal additives, especially things like sugar and milk, is the way to go when it comes to adding tea to your daily intake,” Simper adds.

Benefits of herbal teas

Depending on which symptoms you’re dealing with, or health benefit you’re looking for, different herbal teas have different purposes.

-          Peppermint teas – Helps with upset stomach

-          Ginger tea – Helps with nausea

-          Chamomile teas – Can help decrease cardiovascular disease and some cancers. It can also help with premenstrual syndrome and help boost immunity, Simper says.

But what about all the caffeine?

“The caffeine in tea is about half the amount of coffee. You would have to drink eight or more cups of tea a day to get to that highest level we would recommend for caffeine. So, it’s not that much of a risk for people,” Simper points out. “However, if you’re going to start drinking three to five cups of tea a day, and you’re not normally a caffeine consumer, you might notice the effects of the caffeine.”

Connection to weight loss

If you’re looking to tea for weight loss, you might be waiting for some time, Simper says. She says the research is conflicting, and weight loss is minimal due to drinking tea. However, switching out caffeinated tea for sodas and coffees filled with sugar would be the healthier choice.

Feeling bloated today? You’re not alone.

It’s not uncommon to get the sensation caused by gas, air or fluid retention in the stomach or small intestine. But what’s important to know: bloating has many causes, says Aminat Ogun, MD, an OSF HealthCare family medicine physician. So don’t let it linger and hope it will go away. If symptoms persist, see a health care provider so they can rule out something more serious and give proper treatment.

“It might feel like your stomach is full, swollen or sometimes tender. It can cause some discomfort,” Dr. Ogun says.

Causes for bloating include:

• The body makes too much gas.
   
• An overgrowth of intestinal bacteria. H. pylori is a common type. Dr. Ogun says it causes chronic inflammation in the stomach lining, and it can lead to peptic ulcers or even stomach cancer if untreated.
   
• Diet issues, like intolerance of certain carbohydrates or a gluten intolerance.
   
• Hormone changes during a woman’s menstrual cycle.
   
• Abnormal gastrointestinal motility. Simply put, this is when your gut is not working properly. Dr. Ogun says one example is gastroparesis.

              “The body takes its time before its able to pass food from the stomach to the small intestine,” she explains.

• Stress, anxiety and depression.

Dr. Ogun points out that we can’t control some of those causes, but others we can. She says a typical first step for a person with bloating is to change their diet. She says doctors may recommend a diet with a long name: fermentable oligosaccharides, disaccharides, monosaccharides and polyols. But just remember the abbreviation: FODMAP. It describes carbohydrates that are difficult for the body to break down.

Foods to avoid on the FODMAP diet: pasta, cereal, bread, yogurt, ice cream, apples, cherries and peaches. Alternatives include quinoa, brown rice, eggs, cheese, grapes, strawberries, chamomile tea, peppermint tea and ginger tea.

“Have a food diary,” Dr. Ogun suggests. “See what triggers your bloating symptoms and see if you can eliminate those foods.”

People with bloating may also take medicine like Gas-X. If you have intestinal bacteria, you’ll be on antibiotic medication.

Dr. Ogun adds for people age 55 and up, bloating is less common, and other health issues are, simply due to older age. So, if you are of that age and have sudden bloating symptoms, see a provider to find out if your symptoms are bloating or something more serious. And for all ages, if you have severe diarrhea, nausea, vomiting or unintentional weight loss, stop by a doctor’s office.

Recent reports from the United States Centers for Disease Control and Prevention (CDC) are again raising awareness of hepatitis C.

A 2022 report found “too few people diagnosed with hepatitis C are being treated, despite availability of medications capable of curing this viral infection.” Specifically, the agency estimates fewer than one in three people with health insurance are getting direct-acting antiviral treatment for the infection within a year of diagnosis. A June 2023 study published by the CDC also examined gaps in access to treatment, building on the 2022 findings.

The statistics resonate with Marcie Lindstrom, a gastroenterology advanced practice provider at OSF HealthCare.

“If we go back 10 or 15 years, hepatitis C treatment was really difficult,” Lindstrom notes as a possible reason for the hesitancy. “Treatment lasted a year or a year and a half. It required an injection. People really felt bad during treatment.”

Conversely: “Treatment today is so easy. It’s completed in as little as eight weeks. It’s a pill. No more injections,” Lindstrom says.

The basics

Lindstrom says hepatitis – whether A, B, C, D or E – describes inflammation of the liver. She says hepatitis C is a blood-borne virus, and doctors over the years have settled on some common ways it spreads:

• A blood transfusion prior to 1992. Prior to that time, screening blood donors for diseases was not reliable.
• A tattoo or piercing at a place that’s not regulated
• Men who have unprotected sexual relations with men
• People who use illegal drugs, either through a needle injection or snorting through the nose

“Often people are at parties and sharing a straw or dollar bill to ingest. There are a lot of blood capillaries inside the nose. Those can break open,” and blood can spread, Lindstrom says.

Lindstrom calls hepatitis C a silent ailment due to a lack of symptoms.

“Many people can have hepatitis C for decades before they become aware of it,” she says.

Even worse, when a person does have symptoms, they may be vague and tough to distinguish from everyday problems. Fatigue and body aches are common complaints.

Often, Lindstrom says a provider discovers hepatitis C after a person comes in for some routine bloodwork. The bloodwork may come back showing elevated liver enzymes, and a test specifically for hepatitis – also a simple blood test – would then be done.

But if you have any hepatitis C risk factors, you should talk to your health care provider about when you need to be screened. A provider may recommend a screening once a year. And generally, federal guidelines say all adults should be screened for hepatitis C once in their life, and all pregnant women should be tested during each pregnancy. Ask your provider about it when you’re younger rather than older, Lindstrom pleads.

Why it’s important

Untreated hepatitis C can lead to liver scarring known as cirrhosis. That means fewer cells doing their daily functions, which, in turn, can lead to liver failure, liver cancer and even death.

“That’s why treatment is important. We don’t want people to progress to getting cirrhosis,” Lindstrom says. “If they take their eight to 12 weeks of treatment and don’t have a lot of scarring, we have a high success rate in clearing the virus – 98 to 100%.”

Hepatitis B: Prevention and treatment

As many as 2 billion people worldwide will be exposed to hepatitis B during their lifetime, says David Rzepczynski, MD, a gastroenterologist at OSF HealthCare in Urbana, Illinois. Around 250 million people have chronic inflammation of the liver from hepatitis B or are carriers of the virus without inflammation. And around 890,000 people will die from hepatitis B. Asia and Africa are hepatitis B hotspots, Dr. Rzepczynski says, while the United States doesn’t have it as bad.

The statistics might make eyeballs widen, but Dr. Rzepczynski says they are not a reason to panic.

“The majority of people who get exposed to hepatitis B in the adult age – after age 10 – it’s typically a condition you recover from without chronic inflammation,” he says.

The reason for the optimism? There’s a vaccine for hepatitis B that’s been around since the 1980s.

“There has been an aggressive program of initiating vaccines with kids, sometimes even as young as infants, to have protection,” Dr. Rzepczynski says. “And when those [vaccines] are administered at a young age, it’s a highly effective vaccination. This vaccination has an efficacy of 95%-plus in the general population.”

The three-shot series is sometimes given soon after birth due to concerns that the mother may pass along hepatitis B to their child. But older children and adults can and should get the vaccine, too.

A hepatitis B immune globulin shot (HBIG for short) may also be appropriate in cases of hepatitis B exposure, either in adults or newborns. The particles in the shot attack the virus.

The next best way to avoid hepatitis B is to avoid risky behaviors.

Don’t share needles, toothbrushes or any other object that can transfer bodily fluids. Practice safe sexual relations. And if you’re bleeding, bandage it up right away.

Treatment

Dr. Rzepczynski says blood tests and watching symptoms can gauge how the virus is behaving. That will determine whether the person just needs monitoring. Or the patient may need medical treatment to suppress the virus and prevent cirrhosis of the liver. These medicines are taken by mouth, and side effects are generally not significant. A vaccine to eliminate hepatitis B hasn’t been discovered yet.

Treatment plans for hepatitis B may be life-long.

“If you stop taking the medicine, it’s like taking the brakes off the system,” Dr. Rzepczynski explains. “The virus will end up reactivating. And in fact, that reactivation might cause liver failure because the virus level skyrockets. And your body’s immune system senses that and starts attacking the liver to get rid of the virus. And that can lead to very serious and acute inflammation of the liver.”

Should I test?

Dr. Rzepczynski says a blood test for hepatitis B isn’t something that constantly needs to be on the mind of the average person. But the following people should consider getting tested:

·       People who come from areas of the world with a high prevalence of hepatitis B

·       Pregnant women

·       If you plan to donate blood or organs

·       People who’ve had an exposure to the virus

·       People getting chemotherapy for cancer treatment

That last one is something medical professionals have looked closely at in the last five years.

“Unfortunately, some of these powerful cancer agents also have the ability to affect the immune system in such a way that a person who’s had hepatitis B and maybe even has gotten over it can have a reactivation of hepatitis B when these particular agents are used,” Dr. Rzepczynski says.

In that case, your cancer doctor would alter the treatment to allow it to proceed without the hepatitis B risk.

Be proactive

If you have questions about hepatitis B, want to get the vaccine or think you may have been exposed to the virus, talk to your primary care provider right away. The OSF HealthCare and U.S. Centers for Disease Control and Prevention websites also have information on hepatitis.
