Gastrointestinal GI Functional Medicine Doctor in Texas

If a patient has been told their digestive tests are normal, but they are still struggling with bloating, reflux, constipation, or chronic GI discomfort, there may be underlying physiological factors that standard testing has not yet explored. Functional Medicine of Houston looks deeper.

The Modern GI Problem

Why So Many People Are Struggling With Digestive Health — And Not Getting Answers

What a person puts into their body determines whether it has the raw materials needed to produce the hormones, enzymes, minerals, and vitamins that keep cells healthy. When the body receives processed foods, chemical additives, and refined ingredients it cannot readily use, the gastrointestinal system — including the liver — may come under significant strain.

Over time, that strain may contribute to a range of digestive and systemic concerns that conventional medicine struggles to fully explain. Our functional medicine dr explores what may be driving those concerns at the root level.

The Gut Connection

What Chronic Digestive Strain May Be Doing to the Body

The gastrointestinal system houses the majority of the body’s immune tissue and maintains a delicate microbiome balance that affects health well beyond digestion. When that balance is disrupted, patterns may emerge gradually — until bloating, discomfort, and irregular bowel habits become a patient’s normal.

Common experiences patients describe may include:

  • Constipation or chronic diarrhea
  • Bloating, gas, and abdominal discomfort after eating
  • Leaky gut patterns and food sensitivities
  • Skin rashes or allergic reactions with a possible GI connection
  • Sugar cravings and unexplained weight changes
  • GERD and reflux symptoms that return despite medication
The Gap in Conventional GI Care

When Your Doctor Says Everything Looks Normal

Many patients have already been through the conventional gastroenterology workup. They have had colonoscopies, endoscopies, and standard stool testing. They have a diagnosis — IBS, GERD, or inflammatory bowel disease — and have been told their results were otherwise unremarkable.

For many of those patients, that answer does not feel complete. They know something has changed. They just have not found a provider willing to look at why.

That is the gap Functional Medicine of Houston was built to explore.

The Functional Medicine Approach to GI Health

A Root-Cause Approach to Digestive Health Concerns

Functional Medicine of Houston does not treat gastrointestinal conditions. What the practice does is look for the underlying physiological factors that may be contributing to a patient’s digestive concerns — and build a protocol designed to support the body’s natural ability to maintain GI balance.

That process begins with a thorough intake. Dr. Stowe reviews digestive history, prior diagnoses, medication history, and dietary patterns. From there, advanced laboratory testing may help identify specific patterns worth exploring.

What Testing May Reveal

Depending on what a patient’s history and intake suggest, functional medicine testing in this area may explore:

  • Gut microbiome composition and bacterial diversity
  • SIBO — small intestinal bacterial overgrowth
  • Intestinal permeability — leaky gut patterns
  • Food sensitivity and food allergy markers — IgG, IgA, and IgG4, C3d
  • Digestive enzyme activity and nutrient status
  • Inflammatory markers and environmental toxin burden

The goal is a more complete picture of what may be contributing — not a one-size-fits-all answer.

Functional Medicine of Houston does not diagnose, treat, cure, or prevent any disease or medical condition. Services are intended to support the body’s natural processes and are not a substitute for care from a licensed primary care provider.

FAQ

Frequently Asked Questions

Can a functional medicine doctor help with IBS?
Functional Medicine of Houston does not treat IBS. What the practice does is look for underlying physiological factors — such as SIBO, dysbiosis, and food sensitivities — that may be contributing to a patient’s digestive concerns.
What is leaky gut?
Leaky gut, sometimes called intestinal permeability, describes a pattern in which the gut lining may become more permeable than typical. Functional medicine testing may help explore whether this pattern is a relevant contributing factor.
What is SIBO?
SIBO describes a pattern in which bacteria may be present in excessive quantities in the small intestine — a pattern that may be a contributing factor in bloating, gas, and abdominal discomfort that standard care does not always evaluate. Took out
Why do I still have symptoms if my colonoscopy was normal?
A colonoscopy evaluates structural integrity — not gut microbiome composition, food sensitivities, SIBO, or intestinal permeability. Functional medicine testing explores these areas as part of a more complete GI evaluation.
What is the connection between gut health and skin concerns?
The tissue lining the GI system and the skin share a similar cellular origin. Patterns affecting the gut lining may be associated with immune responses that some patients experience as skin reactions. Functional medicine explores these connections when a patient’s history suggests they may be relevant.
Can functional medicine explore GERD
Yes. Functional medicine explores a broader range of contributing factors than conventional treatment typically evaluates — including whether insufficient stomach acid rather than excess acid may be a relevant factor, particularly in patients over 50.
What about unexplained weight changes?
Weight gain despite appropriate dietary and lifestyle efforts may involve adrenal function patterns, thyroid markers, and GI system factors. Unexplained weight loss warrants primary care evaluation first — functional medicine may explore contributing factors once known medical causes have been ruled out.
Do I need to stop my current medications?
No. Functional Medicine of Houston does not advise patients to discontinue any prescribed medications without first consulting the physician who prescribed them.
Does the practice accept insurance?
No. Functional Medicine of Houston operates on a cash-pay basis. This allows Dr. Stowe to order the specific tests a patient’s situation warrants without third-party restrictions on coverage.
How do I get started?
The first step is requesting a consultation through the website or by calling (713) 667-6656. Functional Medicine of Houston is currently accepting new patients across all of Texas.
