Welcome to the Tampa Blog of Dr. Matt Lewis

I’m glad you’re here. I have more than six years of postdoctoral education in functional medicine and over a decade of experience in clinical nutrition. Through my Tampa-based practice, I help patients by identifying the underlying causes of low thyroid, fatigue, weight gain, and other chronic health issues and provide holistic treatment through nutrition, lifestyle, and other natural approaches.

While there’s probably only a handful of Philadelphia Eagles fans living here in Tampa, Fla., the team’s 2018 Super Bowl-winning quarterback Nick Foles has certainly been highlighted in the news lately.

That’s because Foles and his wife, Tori, have brought public attention to a private issue within their family. Tori Foles was recently diagnosed with postural orthostatic tachycardia syndrome — better known as POTS — which is an often undetected and underdiagnosed chronic syndrome that causes an increased heartbeat, fatigue, dizziness, and fainting.

POTS patients like Tori Foles frequently find themselves at battle with gravity, which is why this disorder is often referred to as “the fainting disease.” The human heart normally beats 70 to 80 times per minute when we are at rest. That rate climbs another 10 to 15 beats per minute when standing up, then settles back down. But for people with postural orthostatic tachycardia syndrome, the heart rate often increases 30 to 50 beats per minute — or more — leading to the lightheadedness, dizziness and fainting that Tori Foles experienced.

While the plight of those suffering POTS became more visible last month when Tori Foles took her case to news outlets and a CNN audience, many of us in healthcare — especially those of us who practice functional and integrative healthcare — are committed to raising awareness about the disorder, and the misconceptions and frequent poor diagnoses surrounding POTS.

Women and the Misdiagnosis of POTS

Between one and three million Americans suffer from postural orthostatic tachycardia syndrome, and 80 percent of them are young women — particularly those in their early teens — with the condition getting worse through the growing years. Because these women are younger and otherwise appear healthy when the disorder strikes, doctors often dismiss the physical prognosis, choosing instead to explore the Continue reading…

One of the more recent studies to highlight the negative health impact of sugar and artificial sweeteners is “The Influence of Sugar and Artificial Sweeteners on Vascular Health during the Onset and Progression of Diabetes,” by Brian Hoffman, Ph.D., an assistant professor in the Department of Biomedical Engineering at the Marquette University and Medical College of Wisconsin in Milwaukee.

In his study, Hoffman points out that high amounts of dietary sugar have been known for some time to contribute to a wide range of systemic health problems, including obesity, diabetes, and cardiovascular disease. He also points out that “it was not until recently that the negative impact of consuming non-caloric artificial sweeteners in the place of sugar had been increasingly recognized as a potential contributor to the dramatic increase in diabetes and obesity, along with the associated complications.”

The fact that artificial sweeteners had been on the market for so many years before being proven to cause serious health problems is, unfortunately, no surprise. Companies are allowed to profit (and withhold information from the public) until their products are proven dangerous. The burden of proof for the safety of their products is rarely placed on the Frankenfood manufactures. Instead, consumers, doctors, and researches carry the burden of proof that a product is unsafe, and then it takes years to decades before the Food and Drug Administration issues a warning or orders the products off the shelves, assuming it ever does.

To the uninformed, the term allostatic load probably sounds more like a setting on your washing machine than a symptom of stress, but if your doctor suspects allostasis, he or she is telling you that your body may be picking up the tab for your stress-filled life.

Allostatic load is a culmination of all the overtaxed pressures in your life, whether that be work related, the result of relationships, health fears, and even past traumatic events that keep cropping up despite our best efforts.

These issues are bad enough by themselves, but then you toss in a diet that features too much sugar or salt, a caffeine habit that keeps you jittery all day, 24-hour news reports that feature no good news, and what you end up with is allostatic load.

Allostasis is a process that includes the release of stress hormones and neurotransmitters within the body. Each of these stress responses take a toll on your physical condition, which in turn only adds to your allostatic load. The end result of this stress buildup? You become sick.

In recent years, many doctors and health practitioners have suggested diet and exercise as a holistic means of relieving stress. And on the surface, a strict diet can make perfect sense. Where it goes wrong — especially when your allostatic load is at a high level — is the accompanying increase in Continue reading…

If you enjoyed Part I in our series about hormone replacement therapy (HRT), today’s post will complete the picture, especially with respect to what’s involved in HRT itself.

Hormone replacement therapy involves taking one or more sex hormones — estrogen, progesterone, testosterone. While we use the term “sex hormones,” these hormones are also important for heart, brain, bone, and immune system health and for mental health. Having adequate, balanced hormone levels along with healthy hormone receptors, reduces the risk of cardiovascular disease, diabetes, breast cancer, prostate cancer, and dementia. Optimizing hormones reduces risk factors for many of the chronic conditions that increase with age.

HRT can be delivered via different routes, including oral (pills), injection, topically (creams or patches), or inserted into the skin as tiny pellets. The mode of delivery is determined with your doctor based on your specific needs and preferences. Pellet therapies injected into the skin can be done every three months in your doctor’s office. Pills or creams are administered daily and do not require any Continue reading…

Hormone replacement therapy has gotten a lot of press over the years — both good and bad. It all started in the 1960s, when women in their 40s and 50s were prescribed estrogen to alleviate the symptoms of menopause — hot flashes, night sweats, irritability, and mood swings. Then, studies appeared, showing estrogen promotes growth of the uterine lining, which increases the risk of cancer, so doctors began recommending the addition of progesterone to protect the uterus.

However, instead of providing patients with bioidentical estrogen and progesterone, pharmaceutical companies created a synthetic form of progesterone called progestin (which they could patent) and started combining it with various forms of estrogen — synthetic or derived from animals.

At about this same time (the late 1990s), theories emerged suggesting hormone replacement therapy (HRT) would be helpful for preventing certain age-related diseases in older women, and doctors began prescribing it for women in their 60s and 70s. However, in 2002, a large federal study by the U.S. National Institutes of Health called the Women’s Health Initiative linked the leading HRT medication, Wyeth’s Prempro, with an increased risk of cancer, stroke, and blood clotting. As a result of that study and others, many doctors and women abandoned hormone replacement therapy or now use it only to help alleviate symptoms during menopause.

The truth is that hormone replacement therapy is safe and effective for both men and women, as long as it is done right. Doing it right involves addressing other underlying health issues first and then using bioidentical hormones instead of Continue reading…

Nearly 5 percent of the nation’s population over the age of 12 suffers from hypothyroidism, with older women more likely than any other age group to experience this condition.

Hypothyroidism occurs when the thyroid gland — located in the front lower part of the neck below the voice box— doesn’t produce enough thyroid hormones to keep up with the needs of the body. Simply put, the thyroid is underactive.

And that becomes a problem, because the thyroid is charged with overseeing the function of your metabolism, which determines how your body uses energy from food. For those suffering an underactive thyroid, body processes can slow down, which upsets the normal balance of chemical reactions to your body.

What are some of the signs? If you have any of the following symptoms, you may be suffering from hypothyroidism:

Aches and pains Anxiety
Constipation Depression
Dry skin Elevated cholesterol
Fatigue Hair loss or thinning
High or low blood sugar Memory loss
Morning headaches Restless sleep
Swelling of the face or body Weight gain or difficulty losing weight even with diet and exercise

These are just the short-term impacts. The long-term impacts are even more serious: Continue reading…

Editor’s Note: In this post, we offer suggestions, advice and warnings for anyone who is looking for a doctor in Tampa and in particular, those who are seeking a functional medicine and integrative healthcare provider. We hope this Q&A — featuring the thoughts of Dr. Matthew Lewis — proves to be informative in that search. Dr. Lewis is a Doctor of Chiropractic (D.C.), a Diplomate of the American Clinical Board of Nutrition (DACBN), and a Certified Functional Medical Practitioner (CFMP®).

Q: Aside from a Google search, asking a friend, consulting with your insurer, or driving past a doctor’s office that appears inviting enough to walk inside, what are specific ways people can find a functional medicine doctor in Tampa who fits their needs?

A: Many functional medicine-trained doctors provide a public education service on their websites in the form of blog posts, articles or recordings of webinars. Same with their Facebook pages — assuming they use social media to engage with and educate patients. These can be helpful in offering potential patients more information about the doctor and his or her practice, as well as provide important insights into that doctor’s specific areas of expertise.

Intermittent fasting can produce amazing clinical results — especially if you create a step-by-step plan that is simple to stick to and fits in comfortably with your daily schedule and lifestyle.

In my clinical experience, I have consulted with many patients for whom the prospect of fasting holds the fear of excruciating hunger or near-starvation. I’m here to tell you that intermittent fasting is actually an easy approach to healthy eating that doesn’t require huge changes to your daily routine.

We’ll talk more about that process later on in this post.

What do you plan to achieve?

But first things first. Before I recommend such an approach to eating with any patient, there’s a little  Continue reading…

Detoxing flushes toxins from the body. Unfortunately, some toxins resist and remain in the body. Over time, the levels of these toxins rise causing various health issues. To remove these toxins, you need toxin binders that attach to the toxins making them easier for your body to eliminate.

Toxin binders are similar to soap molecules, each of which has two ends — one end of a soap molecule attaches to a water molecule and the other attaches to an oil molecule. This is how soapy water removes dirt and grease from dishes, laundry, and even your body.

Toxin binders work the same way, attaching to toxins and bodily fluids, so the combination can flush the toxins out of the body. Think of toxin binders as tiny sponges that sop up poisonous debris.

Recognizing Sources of Toxins

Toxins enter our bodies from the food and beverages we consume, the air we breathe, certain substances we are exposed to, and organisms that live in our bodies and produce their own waste products. Common sources of toxins include: Continue reading…

The conventional approaches to the treatment and management of diabetes is the single worst case of mismanagement in medicine today!

Full disclosure: My family history is riddled with diabetes — uncles, aunts, grandparents, and parents all with diabetes. These were not overweight people. Not by today’s standards. They had a genetic predisposition for sure. However, each had a chance to control the disease and failed miserably.

Besides genetics, what did they have in common? They all used the conventional approach to diabetes care: Lowering blood sugar by any means necessary, including using prescription drugs and insulin injections, which increase the risk of long-term complications including heart disease and cancer. Diabetics using the pharmaceutical heavy model are destined to remain reliant on the medical system.

Diabetes treatment in the current conventional health care environment will not reverse diabetes and in many cases will actually aggravate the underlying causes of the illness, leading to more chronic conditions and long-term complications.

How can we expect to reverse something with medicine if we never address the root cause?

Asking Better Questions

Conventional medicine approaches diabetes treatment with the wrong question: “How can we lower the patient’s blood sugar?”

A better question is this: “What are some root causes of blood sugar problems and what can we do to resolve them?”

The underlying causes of blood sugar problems include the following: Continue reading…
