Digestive Health

There's more to digestive health than just "regular movements". In fact, science has only scratched the surface of what makes for a healthy, happy digestive system. If you've ever suffered from a chronic gut problem, you know that it can negatively affect your quality of life in a myriad of ways. And if you're tired of seeing doctor after doctor without any clear answers, it's time to take a different approach.

The Gut is Just the Beginning

At Internal Healing and Wellness MD, Dr. Khan and his team have been treating patients with digestive issues, in Greater Houston, for years – with great success. Functional medicine teaches us to see the gut as the center of all bodily wellness, which is why we take a holistic approach to find the root cause of your intestinal problems. Part of this means focusing on the health of the microbiome while also considering nutrition, diet, allergies, and countless hard-to-diagnose conditions that may be affecting (or emanating from) your stomach. As always, we don't just treat the symptoms. Instead, we dig deep to find the root of the problem so we can take a more comprehensive approach to your recovery.


Our team is fully experienced in dealing with:


Constipation can have a lot of different causes, from physical inactivity to simple dehydration. When it becomes chronic, however, it’s important to have the situation evaluated by a professional.

Crohn’s Disease

Crohn’s disease is an inflammation of the digestive tract that can cause life-threatening complications if left untreated. However, it can be managed with the right treatment plan.

Genetic Parasite Tests and Identification

We can test and identify potential parasites within your gut using methods that are far more accurate than traditional “visual inspections.”


Diarrhea is your body signaling that something is wrong. We can help you decode those signals and renormalize your digestive system.


Like many other conditions on this list, gas and bloating are usually symptoms of a larger digestive problem. We help figure out what that underlying issue might be so we can treat it as soon as possible.

Irritable Bowel Syndrome

IBS is one of the hardest digestive disorders to identify and can greatly affect your overall wellbeing. We help you find out which foods and habits might be affecting your situation and plan a strategy for total relief.

Microbiome Evaluation

Your microbiome is a unique genetic fingerprint. Because it is largely inherited from your mother, you can inherit a variety of disorders, intolerances, and more. We can help you learn exactly what your microbiome needs to be healthy (and what you need to avoid).

Food Sensitivities

With proper testing, we can help identify sensitives to glucose, lactose, gluten, and other types of foods and ingredients.


GERD is one of the most pervasive and common digestive disorders, but it can also be very diificult to treat. Over time, it can also cause irreparable damage to the esophagus.

Functional Gut Health Tests

Our digestive health tests can identify a wide range of poor digestive issues, food intolerances, bacterial overgrowth, parasitic infections, leaky gut, and more.


Many people suffer from IBD due to Small Intestinal Bacterial Overgrowth (SIBO), a condition that occurs when healthy bacteria begin overtaking the small intestine. We can not only test for this condition but provide specific treatment strategies to help you overcome it.


These sores in the lining of your stomach and intestine can become inflamed and lead to significant pain. Not only can we help you heal ulcers quickly but identify the cause so that you can keep them from returning.

Genetic Gut Microbial Tests

These tests help us determine the ratio of various types of bacteria within the gut, allowing us to compare ratios to those of healthy levels to decide how close your bowel movements are to the normal range.

Leaky Gut

Over time, your intestinal lining may develop cracks or holes, allowing food and toxins to penetrate the tissues underneath. With the right approach, it is possible to improve the condition and rebuild your intestinal barrier.

Comprehensive Food Testing Panels in Greater Houston

Internal Healing and Wellness MD has already helped thousands of people Spring, The Woodlands, and Conroe discover the real root causes behind their food allergy symptoms. Through a variety of testing methods and panels, we can help determine sensitivities and intolerances to a variety of foods and food types, then help you develop a strategy for eliminating those elements from your diet.
