A vitamin D-lightful summer

Tue, 04 Aug 2026 08:00:00 -0500

Summer is a time to soak up the sun. Sun rays are a primary source of vitamin D, an important tool for our body. Should you be concerned that you’re getting too much or too little vitamin D? Experts say if you know your body and take the usual sun precautions, you should have a worry-free summer.

Vitamin D basics

Maddy Draper, APRN, a health care provider at OSF OnCall, says vitamin D is a nutrient our body needs to produce calcium. Calcium helps create strong teeth and bones. So logically, not having enough vitamin D leads to brittle bones (a risk for greater injury after a fall), plus muscle aches and pains. Others with a vitamin D deficiency may not show symptoms. Either way, a provider may order a blood test to confirm the issue and then may advise you to take a supplement. This is usually in pill form and can be prescribed or bought over the counter by itself or as part of a multivitamin.

“Or the provider may just talk about vitamin D-rich foods first before starting a supplement,” Draper says. “High fat fishes, egg yolks, some cheeses and mushrooms.”

Draper adds that pregnant women, babies (especially babies who are breastfed), the elderly and people with darker skin often lack vitamin D.

On the flip side, Draper says it’s rare, but a person can get too much vitamin D. Symptoms include nausea, vomiting and heart palpitations (feeling like your heartbeat is fast, pounding or otherwise irregular). You may also suffer kidney damage.

Summer sun

Here’s advice to commit to memory: Draper says research shows 10 to 15 minutes of sun exposure three times a day can get you a healthy amount of vitamin D.

“You want to protect your skin while doing that,” Draper adds. “Sunscreen and protective clothing like a hat and sunglasses. There’s not any research showing that sunscreen or clothes will prevent you from getting the vitamin D you need.”

Experts say your sunscreen should have a sun protection factor (SPF) of 30 or higher, and you should reapply every two hours. Clothing should be lightweight and light colored (Dark colors absorb more sunlight, leading to quicker heat illness.) Stay hydrated, and watch for redness and blisters from sunburns and suspicious moles that may be skin cancer. See a provider right away if you have issues from getting too much sun.

Another thing to note: Experts say a specialized lamp can help with seasonal affective disorder, a mental health condition often seen in the winter due to decreased daylight. The same logic does not apply for vitamin D. You need natural, not artificial light to get the vitamin D you need.

The bottom line

Draper says most people don’t have to worry about getting too much or too little vitamin D.

“The average person will get it through the sun,” Draper says. “If you live in a cold and dark environment, you’re at higher risk for vitamin D deficiency. People farther away from the equator are higher risk.”

If you have symptoms of too much or too little vitamin D or just have a concern, talk to your primary care provider.

Planes, trains, automobiles…and your health (part one)

Thu, 28 May 2026 08:00:00 -0500

Author's note: this is part one of a two part story on staying healthy during summer vacations. Click here for part two.

Summer means getaways to de-stress and make memories. But the last thing you want is to catch a cold or worse, especially if you’re halfway across the world where health care resources might be different or scarce.

It's not too late to make some quick preparations, says Jennifer Whitfill, APRN, a family nurse practitioner at OSF HealthCare.

Stop by the doctor’s office: Whitfill says if you haven’t seen your primary care provider for a physical exam in a while, make an appointment before vacation to address any lingering health issues. This could include getting vaccines depending on your health and where you’re going. Whitfill says typhoid fever (seen in southern Africa, Asia, Central America and South America), yellow fever (Africa), hepatitis A (remote or underdeveloped areas) and rabies are ailments to protect yourself against.
Stock up on over-the-counter medication.

“It’s important to be prepared,” for when these medications are needed, Whitfill says. “Consider packing Tylenol or ibuprofen, anti-allergy medicines like Claritin, Zyrtec and Benadryl. Dramamine is a good one for motion sickness or nausea. Some people reach out to their provider if they’re going on a cruise. There’s a prescription called a scopolamine patch that you can put behind your ear. It’s good for three days and helps offset motion sickness.

“Eyedrops are good if you have seasonal allergies. Over-the-counter saline or Pataday drops,” Whitfill adds. “Creams like hydrocortisone and triple antibiotic ointment are good to have.”

For outdoor trips like camping, essentials including a first aid kit, sunscreen and bug spray are must-haves, too. Know if you’re on a medication, such as certain acne creams and menstrual cycle medications, that makes you more prone to sunburn.

And regardless of what you pack, Whitfill says flyers should check the Transportation Security Administration guidelines about what can come on a plane. She says to leave medicines in their original packaging when preparing airport luggage.

Medicine, part two – before you go: You might hear travel bloggers say to boost your immune health before traveling to reduce your risk of catching something. Is the advice overblown?

Whitfill says no. She says elderberry, vitamin C and D and zinc are all good supplements to take before a trip. Start three to four weeks before departure, if you can. And if you have concerns about supplements interacting with prescription medication, talk to your provider.

Perimenopause: ‘You’re not alone’

Mon, 23 Feb 2026 09:18:38 -0600

As women age, new adventures come. Some, like travel and new hobbies, can bring joy. Others can bring stress.

One of those stressors is perimenopause, the time you’re transitioning to menopause, when you permanently stop having menstrual periods and can no longer get pregnant.

“There’s a stigma around this time of life,” says Lindsay Orr, an advanced practice nurse at OSF HealthCare. “It’s not an illness. It’s just a natural part of aging.”

Perimenopause basics

Orr says during perimenopause, the ovaries stop producing testosterone, estrogen and progesterone regularly.

“Think of it as a short fuse or a fuse that’s not quite connected,” Orr describes. “Every month, the hormones secrete. But ovaries have a shelf life. So some months they work, and some months they don’t. It ebbs and flows during the perimenopause transition period before they go into menopause.”

Orr says women typically notice changes that signal perimenopause at around age 40. The perimenopause period can be over quickly, especially if you have surgery that impacts your ovaries. On the other hand, Orr has seen some women be in perimenopause for 10 years. Regardless, health professionals define the perimenopause to menopause transition as over when you have not had a period for one year.

Orr says some women can have little to no perimenopause symptoms. For others, the time can bring disruptions to many parts of your life – work, sleep, relationships and more. Sudden hot flashes, mood changes, joint aches, brain fog, trouble with urination, anxiety, disrupted sleep and fatigue are all possible.

“A lack of estrogen can affect bone density,” Orr adds. “So women with smaller frames are more predisposed to bone issues if they fall. Or, a decline in estrogen can have cardio-protective effects. It can increase your risk for cardiovascular issues like heart disease.”

Anorexia, bulimia, high stress, smoking, drinking alcohol and being a high intensity athlete can also make perimenopause come sooner and be more intense, Orr says.

Treatment – proactive and reactive

Orr says if perimenopause symptoms are impacting your quality of life, it’s time to see a provider. Providers can’t make perimenopause go away, but they can help with symptoms. First, Orr asks if her patients are prioritizing what she calls the “four pillars of health”: exercise with resistance training, hydration, a healthy diet with plenty of protein and healthy sleep.

A provider might also recommend a supplement, such as diindolylmethane (or DIM, for short). Orr calls DIM broccoli in a pill. It helps keep hormones at a healthy level. Other supplements that could help include calcium D-glucarate, evening primrose oil, black cohosh and ashwagandha.

Orr also urges women to start the conversation with their primary care provider or OB/GYN before perimenopause hits. Ask what you can do now to lessen symptoms or duration. Be honest about how your body is feeling and what medications you’re on, as new medications could negatively interact with current ones. Orr also recommends women use a smartphone app to track their periods.

“The apps help you be in tune with your body. You go through your day-to-day life and kind of recognize things, but you don’t really put it all together. Then when you put the information in the app, you might say ‘Oh yeah, I am symptomatic. This is happening.’” Orr says. “You can track temperature changes, bleeding issues, hormone fluctuations and sleep. It all plays a role.”

What about pregnancy?

Yes, women can still get pregnant during perimenopause, though it’s not as common as pregnancies in your 30s and younger, Orr says. However, in general, Orr says the higher in age, the higher risk for pregnancy complications.

“Balanced hormones help maintain a good uterine lining for housing a fetus,” Orr explains, noting perimenopause disrupts that hormone balance. “So, a later-life pregnancy would require closer monitoring.” In other words, you’d likely have more trips to the doctor to make sure your pregnancy is healthy.

The bottom line

Orr reiterates: perimenopause is a part of life. Give yourself grace, take advantage of the help that providers can give and recognize that it’s about progress, not perfection.

“Some of the women I see are frazzled, disheveled and anxious. Sometimes they’re upset during the visit. It’s sad to see,” Orr recounts. “Then we start treatment, and I see them three months later. They look like a different person. They’re glowing. They have a zest for life again. It’s rewarding to see.”

Mental health medication and pregnancy

Tue, 13 Jan 2026 08:00:00 -0600

As the stigma around mental health continues to improve, people are more likely to seek treatment. A woman who has just learned she’s pregnant may wonder: should I stop taking medicines like Zoloft or Prozac? Will they hurt my baby?

Sarah Shoemaker, a certified nurse midwife at OSF HealthCare, says first of all, you’re not alone. She says around one in five women experience a mental health concern during pregnancy, and many of those women are taking medication for things like anxiety, depression and bipolar disorder. Shoemaker says most of the time, you can and should stay on your medication. But it’s a conversation you should have with your health care team.

Shoemaker implores women to talk about medication with their provider early Ideally, it’s before they conceive. Shoemaker says don’t change or stop your medicine routine until you have that talk. You may have your child’s best interest in mind, but a change could compromise your or your child’s health.

“There are some women who take years to find the perfect combination of medications that keep them stable and healthy. We don’t want to mess with that. Very rarely do we have to completely disrupt somebody’s medication regimen,” Shoemaker says. “Nothing in our field is black and white. There’s no such thing as bad medication or strictly dangerous medication. We weigh the pros and cons and decide what’s best for each patient.

“If you look online, you’re going to find all kinds of information. You’re going to find conflicting sources, old studies and poorly written studies,” Shoemaker adds, referencing the temptation to rely solely on your own research.

Shoemaker says a provider may order one or more ultrasounds before making a decision on medication. If a provider advises that a change is needed, you could go on a supplement. For example, Shoemaker says a medicine like valproic acid (a seizure medicine sometimes used for bipolar disorder) may increase the risk of neural tube defects (NTDs) in your unborn child. Spina bifida, or the abnormal development of the spinal cord, is a common NTD. In this case, a provider may advise adding a folic acid supplement at a high dose. Shoemaker adds that for medications like valproic acid, drugmakers and doctors are vocal up front: don’t start taking it if you’re trying to get pregnant. That way, you don’t have to possibly make a change mid-pregnancy.

If you’re on a medication that’s new to the market, that’s also a definite “must talk about” with your provider. That’s because we don’t know a lot about how new medications impact pregnancy. Shoemaker points out that scientists typically don’t do intense studies on pregnant women so they don’t disrupt the pregnancy. Rather, the research is done after birth.

“We discuss what the woman is on, how we can counteract the risk and what the actual risk is for her specific situation. Then we can make a shared decision about what is best for her and her family,” Shoemaker says. She adds that the woman’s entire care team – their primary care provider, their mental health provider and their OB/GYN or midwife – should be working together.

Shoemaker admits all this can be a tough task. But there are tried-and-true ways to get to the root of a pregnant woman’s mental health concern. Providers also build extra time into appointments to talk about mental health. Shoemaker says she often uses humor to break the tension. She can also use personal experiences to relate to the mom-to-be. And she’s also not afraid to ask a lot of questions: are you sure there’s nothing else we can talk about? How are you doing emotionally?

“If you continue to ask in new and different ways, women eventually open up. They say ‘yeah, this is really bothering me. I wondered if it was normal. I was afraid to talk about it,’” Shoemaker says. “Once you make it clear that the provider is a safe person to talk to and mental health is really important, women will open up.

“More women need to talk about how difficult it can be to be pregnant, to be a mother and to be going through this huge life transition,” Shoemaker adds.

Navigating menopause: Expert advice for symptom relief

Mon, 27 Oct 2025 09:32:26 -0500

The transition to menopause – when a person permanently stops having menstrual periods – can bring symptoms like hot flashes, night sweats, irregular periods and anxiety. Women may want to find assistance with these symptoms.

Dennis Sands, MD, is an OSF HealthCare gynecologist and chief medical officer at OSF HealthCare Saint Anthony’s Health Center in Alton, Illinois. He cautions you to be wary of over-the-counter medication that claims to help with all menopause symptoms.

“In general, a lot of the at-home remedies are marketed very well. They are touted as cure-alls or things that will work for the most common complaints, like hot flashes,” Dr. Sands says. “What we’ve found is most of them don’t work.”

Dr. Sands adds that these medicines are marketed as dietary supplements, not pharmaceuticals. So, there’s more wiggle room to make claims about their benefits. Dr. Sands says he’s seen menopause medicine labels at the pharmacy that tout vitamin, soy or phytoestrogen ingredients. Equelle is a common brand name. Dr. Sands says these medicines can have a minor effect on menopause symptoms in healthy people, but they are not cure-alls or effective for all people. In particular, he says irregular bleeding usually requires a treatment plan laid out by a health care provider and an evaluation to rule out something more serious.

That’s where your gynecologist comes in, with Dr. Sands reminding that treatment is different for everyone. The first advice you’ll likely hear: keep up with your health.

“We’ve noticed that people who are healthy overall, exercise well, sleep well and are in good relationships generally do pretty well in the menopausal transition,” Dr. Sands says. “The more stress people are under, the more they’re not as healthy as they could be, the more their sleep is disturbed. It seems a lot of those people tend to have a more difficult transition.”

Estrogen patches and progesterone creams can also help, especially in younger women. A provider may also see if other medications you’re taking are making your menopause symptoms worse.

“If you’re struggling, see your provider and review all the options,” Dr. Sands suggests. “There are some great options that are effective and safe. Generally, they’re only used for a short time to get people through the transition.”

The unfiltered, unregulated truth of kava root products

Tue, 23 Sep 2025 08:00:00 -0500

Marketed as a non-alcoholic option for older teens and adults, drinks and supplements with kava root have gained popularity in the last few years.

Manufacturers say the items will help consumers relieve anxiety, decrease stress, become relaxed and even fight addiction. However, there’s major concern about the negative side effects these products can have. They can be bought as drinks, like the Feel Free Classic, or in pill form with powder from the kava plant inside.

The California Department of Public Health says kava’s active ingredient, kavalactones, contain sedative and psychoactive (mind-altering) properties.

Erica Dawkins, a clinical dietitian with OSF HealthCare, dives into the additional health concerns that have been widely reported to have a connection to kava.

"We're seeing nausea and vomiting, dizziness, gastrointestinal distress. Some people are having trouble with their vision," Dawkins says. "Because of all these kavalactones, or active ingredients, some of them tend to damage the liver. Because we're seeing some extra liver damage going on, if you're also taking other medicines, supplements, or drinking alcohol, which can also damage the liver, we're seeing an exacerbated effect of that, too."

In 2002, the U.S. Food & Drug Administration (FDA) issued a consumer advisory about dietary supplements containing kava, saying they might be associated with severe liver injury and hepatoxicity (hepatitis, cirrhosis, liver failure).

Nearly two decades later, the FDA released a memorandum concluding that there’s enough data to suggest that using kava for “recreational” or “relaxation” purposes “is not safe for human consumption.” It lists kava as an unapproved food additive when used as an ingredient in conventional foods.

In addition to the concerning reports released by the FDA, the U.S. Drug Enforcement Agency (DEA) reports that chronic use in large quantities may cause “dry scaly skin or yellow skin discoloration.” This is known as kava dermopathy, as well as causing tremors or other abnormal body movement.

"The safety of these supplements aren't as closely regulated by the FDA,” Dawkins says. "So, I would be very careful and talk to a physician about any alternatives before going down that route."

Kava is native to the South Pacific and is a member of the pepper family, the National Center for Complementary and Integrative Health, a section of the National Institutes of Health (NIH), reports.

Traditionally, kava would be used in ceremonial, social and medical situations. Dawkins says how it’s being produced today offers an added layer of danger.

"Boiled down again, no pun intended, to the way it's being made and manufactured. Back in the traditional sense, a lot of times the root was dried or grounded and then extracted with pure water. Nowadays it’s extracted with alcohol or acetone (colorless, solvent liquid)," Dawkins says. "When it's extracted with those things, you can get a larger amount and an amount that's much more potent and effective than if it were done in the traditional sense."

Dawkins says to speak with your medical provider about speaking with a therapist or counselor. There are other medications out there which can respond more safely and effectively to the issues you're facing, instead of an unregulated product.

At-home migraine relief: Fact vs. fiction

Wed, 05 Mar 2025 07:55:57 -0600

Migraines are a part of life for many. From stress to dehydration to a woman’s menstrual cycle and even more serious issues such as a stroke, the headaches can pop up often. And they’re something you should know how to manage.

Amber Oberheim, APRN, a primary care provider at OSF HealthCare, says migraines can often be treated with ibuprofen (Advil is a common brand name) or naproxen (Aleve), plus lifestyle changes including better sleep. But, an online search will also yield plenty of non-medicinal, at-home remedies. Experts will remind you that these aren’t cure-alls. But it’s important to know what works and what doesn’t.

Myth vs. fact

A cold or warm cloth on the head and neck: Stick to cold, Oberheim says.

“One of the theories for why migraines happen is vasodilation, or increased blood flow to your brain,” Oberheim explains. “So we talk about using a cold compress over your eyes, on the back of your neck or at the top of your head. That cold sensation constricts blood vessels, thereby decreasing blood flow.”

Oberheim adds that there are even migraine caps that stay in the freezer until use. Those are available over the counter at retail outlets.
Rest and deep breathing: Oberheim says there’s no guarantee that your migraine will be gone when you wake up from a nap. But, she says rest and deep breathing can’t hurt. Take a break in a cool, dark room, and avoid screens and loud noises.
Caffeine: It’s good general advice to ingest caffeine in moderation for heart and mental health. But, Oberheim says a soda might help with that headache.

“We look at medications in Excedrin Migraine [pills]. Caffeine is one of them,” Oberheim says. “Caffeine has been proven to be effective sometimes in early management of migraine headaches.”
Supplements: There’s a lot to choose from in this aisle of the pharmacy. And experts warn that you should choose with provider guidance since supplements aren’t regulated like others under the eye of the United States Food and Drug Administration. However, Oberheim says some research has shown that taking vitamin B2 (also called riboflavin) and magnesium daily can help with the number of migraines.
Massaging your head: It’s a tactic some of us learned when we were kids. Massaging your temples (the area between your eyes and the top of your ears) could help with head pain.

“I don’t think there’s any data that would support that. I think it’s more of a comfort,” Oberheim says. “When you’re experiencing pain and you can have a sensation that’s not pain somewhere on your body, it might help lessen the pain.”

For example, Oberheim says when her patients are getting a blood draw through an IV in their elbow, a provider might scratch their upper arm (between the point of pain and the brain) to “confuse” the pain signal and lessen the discomfort. The same logic applies to rubbing your head during a migraine.
Taking a shower: It depends, Oberheim says.

“I could see if stress or muscle tension is creating a headache. Taking a warm shower or bath to relax might help,” Oberheim says. “However, if we’re thinking about a classic migraine with the theory of increased blood flow to the brain, taking a hot bath or shower might actually make it worse.

“It never hurts to try, but I think it’s going to be patient-specific,” she adds.

When in doubt

Oberheim says some people have a history of migraines and know how to manage them. But if the headaches suddenly increase in frequency or intensity, you should see a health care provider. Also, talk to a provider if you have questions about starting or changing at-home treatment. The provider can determine what works for you. You don’t want new medications to negatively interact with drugs you’re already on, for example.

“Often, a migraine can last for longer than a typical headache. It can be accompanied by symptoms like nausea, light sensitivity and noise sensitivity,” Oberheim says, warning of the dangers if migraines are not treated quickly. “There are certain types of migraines that can also affect your vision.”

Temporary decreased function of your limbs is another rare, but possible side effect, Oberheim says.

Diverticulosis: long name, bad condition

Tue, 19 Mar 2024 09:43:00 -0500

The late Senator John McCain and Pope Francis are among the public figures who have dealt with diverticular disease. It’s a common problem in the digestive tract, but it’s one that can have serious complications if not treated properly.

Terminology

David Rzepczynski, MD, an OSF HealthCare gastroenterologist, says it’s important to first lay out some similar sounding terminology.

Diverticulum (singular) or diverticula (plural): These are the bulges that form when an inner part of the colon sticks out through a weak spot in the colon wall.
Diverticulosis: This is the name of the condition when the bulges occur.
Diverticulitis: This describes when the bulges become inflamed.

Causes, symptoms and diagnosis

Dr. Rzepczynski says diverticulosis occurs when your colon is trying to push stool forward, and the organ is not as bulky as it should be. The diverticula bulges then form.

The condition has been more common in people over 60, but Dr. Rzepczynski says health care providers are seeing a rise in cases in people in their 40s and 50s.

Diverticulosis can run in families. It’s also tied to your lifestyle.

“A diet that has more red meat, less grain and less fiber might put you at a higher risk,” Dr. Rzepczynski says.

Smoking, excess alcohol and obesity are also risk factors.

Symptoms of diverticulosis include abdominal pain or constipation. But it often comes with no symptoms and is found during a colonoscopy.

Treatment

Dr. Rzepczynski says in mild cases, a provider may tell you to change your lifestyle, such as getting more fiber in your diet. This makes bowel movements smoother.

“Often, people will look to use fiber supplements,” Dr. Rzepczynski says. “The amount of fiber intake from supplements pales in comparison to what you can get from your diet.”

Also, eat a healthier diet overall. Dr. Rzepczynski says there used to be a myth that nuts, popcorn and seeds would get lodged in the colon bulges. He says studies have shown those foods are not a risk factor.

Other lifestyle tips: exercise and cut out tobacco and alcohol.

Dr. Rzepczynski says more serious cases of diverticulosis can come with two complications. One is bleeding.

“You could have a blood vessel on the outside of the diverticulum. If it ruptures into the diverticulum, it could cause sudden bleeding from the rectum,” Dr. Rzepczynski says.

Dr. Rzepczynski says bleeding from diverticulosis is not common. He ballparks it at around one in 2,000 cases. People on blood thinning medication who develop diverticulosis have a higher risk of bleeding.

While unpleasant, Dr. Rzepczynski says most bleeding cases resolve on their own.

The second, more serious complication is diverticulitis, or when the diverticula bulges become inflamed. This happens when there is a tear in the diverticulum, and bacteria from stool leaks. And it can lead to a host of other problems: pockets of pus known as abscesses, issues passing stool and a urinary tract infection.

Symptoms of diverticulitis include pain in the lower left abdominal area, abnormal bowel movements, nausea and vomiting. If you have these symptoms, it’s important to been seen by a health care provider quickly. A doctor may order a computed tomography scan (commonly called a CT scan) to diagnose diverticulitis.

Dr. Rzepczynski says it’s not common for diverticulosis to progress to diverticulitis, and most cases of diverticulitis can be treated at home with oral medication. But, he says 12 to 15% of diverticulitis patients spend time at the hospital. Treatments there include antibiotic medication through intravenous therapy (IV) and surgery. If surgery is necessary, a doctor will drain any abscesses then remove the inflamed area of the colon.

“They’ll try to reconnect the colon at that time,” Dr. Rzepczynski explains. “But if the surgery is done on an emergency basis, sometimes the person may have a colostomy where part of the colon is coming out through the skin. That’s a temporary measure.”

A colostomy comes with a bag on the outside of your body that collects the waste that would normally leave your body via a bowel movement.

Dr. Rzepczynski warns that surgery isn’t a permanent fix. He says around 15% of diverticulitis patients who have surgery end up with another bout. It reinforces the importance of lifestyle changes. You should also get on a colonoscopy schedule as advised by your health care provider.

Body cleanses: Don’t believe the hype

Fri, 24 Feb 2023 10:35:00 -0600

Andrew Zasada, MD, can’t help but chuckle when asked about the “latest and greatest” body cleansing fads.

But the internal medicine physician at OSF HealthCare says these whims can turn into anything but a laughing matter.

“When you put stuff that’s not really regulated in your body, you don’t know what’s going in,” Dr. Zasada says. “And if you mix in your regular medicine, too, you’re not doing yourself a favor.”

Dr. Zasada is reminding you to talk to your primary care provider before starting any significant treatment. Don’t believe everything you read online or on a label.

Diatomaceous earth as a cleanse

Dr. Zasada says diatomaceous earth has several legitimate uses in industry. But it’s also seen in powder form as a dietary supplement.

The product comes from ground-up and processed skeletons of algae. It contains silica, one of the main components of sand. There are two types of diatomaceous earth: edible, which contains 2% to 4% silica, and industrial with 60% or more silica.

Dr. Zasada says ingesting silica in small amounts – for example, mixing it in water – is harmless because it does not absorb into your body. But you should never inhale it.

“It causes irritation of the lungs which can be permanent and cause scarring. It can cause you to be short of breath. It’s called silicosis,” Dr. Zasada explains. “It’s similar to what coal miners get when they inhale coal dust. People die from silicosis every year.”

Dr. Zasada says some people claim diatomaceous earth cleanses your digestive tract and improves cholesterol. But he says scientific evidence for and against these claims is “scant at best.”

“There have been a few studies that showed that it lowers cholesterol. But at the same time, we don’t know what else that patient may have eaten because it was a poorly designed study,” Dr. Zasada says. “Was the silica responsible? Was it dietary? We simply don’t know.”

Dewormers and other cleanses

Dr. Zasada says dewormers do what the name suggests – remove intestinal parasites from your insides. He says they serve a purpose in livestock but not humans.

“Some people believe we all carry some type of parasite, and we need to deworm ourselves,” Dr. Zasada says with a sigh.

“If you really think you have an intestinal parasite, see your doctor. The test is simple. If you do, in fact, have a parasite, it can be eliminated.”

Dr. Zasada adds that there’s no evidence that our bodies are loaded with toxins that must be removed. He says that removal happens naturally through our liver, kidneys and bowel movements.

“We’ve been around as a species for hundreds of thousands of years without colon cleanses, and we’ve done pretty well,” he quips.
