Digestive Health

There's a lot more to digestive health than "regular bowel movements”. In fact, scientists and researchers have only scratched the surface of what it takes to have a functional and healthy digestive tract. If you've ever had persistent gastrointestinal problems, you know how damaging they can be. Digestive diseases can have a major impact on your way of life on many levels. If you’ve been consulting several digestive health specialists without seeing any improvements or results, then it’s time to try something new.

It Starts with the Gut

Dr. Khan at with his team of digestive health doctors at Internal Healing and Wellness MD, have been helping patients suffering from gastrointestinal difficulties for several years now. They provide their medical expertise in most areas of Greater Houston and The Woodlands, which have been met with great success. The team of doctors use a holistic approach along with Functional Medicine to identify the underlying cause of the patients’ intestinal and gastric problems. According to Functional Medicine the GI system is the center of our well-being. Some of the advantages of Functional Medicine is to prioritize the microbiome's health while also taking into account nutrition, diet, allergies, and a myriad of other complex problems that could be affecting (or arising from) your abdomen. We don't only treat the symptoms like it’s typically done, instead, we put our efforts into finding the source of the illness in order to be able to develop a more holistic treatment plan for you.


Our Team has Extensive Experience in Treating:


Constipation can be caused by a variety of factors, ranging from muscular inactivity to dehydration. Though, once it becomes chronic, it's important to seek professional help.

Crohn’s Disease:

Crohn's disease is a digestive system inflammation that, if left untreated, can lead to life-threatening complications. It can be managed with the right treatment technique and functional medicine methods, commonly prescribed by digestive health specialists.

Genetics or Parasites and their identification:

At Internal Healing and Wellness MD, in Houston and The Woodlands, we make sure to use technics that are far more accurate than traditional "visual examinations" to test for and detect any parasites in the stomach and digestive tract.


Diarrhea is the immune system's way of telling you that there is a problem. Our job is to help you analyze these symptoms and restoring balance to your gastrointestinal tract. It is important to get professional advice from our digestive health doctors for better insight on your problem.


Like most of the other problems relating to digestive health, gas and bloating are frequently signs of a more serious gastrointestinal condition. Our functional medicine doctors help determine what the root of the problem is so that it can be treated as soon as possible.

Irritable Bowel Syndrome:

IBS is one of the most difficult bowel conditions to diagnose, and it can have a significant impact on your general health. By using a holistic and Functional Medicine approach, our team of digestive health doctors can help you figure out which foods and habits are causing your symptoms, and accordingly design a plan to get you back on track.

Microbiome Evaluation:

At our facility in The Woodlands, we consider your microbiome a genetic imprint that is unique to you. You might develop different illnesses, intolerances, and other conditions because of hereditary reasons. Our digestive health professionals have the knowledge and experience to determine what can help your microbiome improve and which habits to avoid.

Food Sensitivities:

Through the use of functional medicine, a holistic lifestyle approach and proper testing, it is possible to identify gastrointestinal sensitivities. These include foods and ingredients containing gluten, lactose and glucose, among others.


GERD is among the most common gastrointestinal issues, but it's also one of the most difficult to cure. We recommend that you schedule an appointment with one of our functional medicine doctors, because with time, it has the potential to cause irreversible damage to the stomach.

Functional Gut Health Tests:

Thanks to our state-of-the-art digestive health testing at our facility in the Houston area and The Woodlands, food allergies, sensitivities, bacterial overgrowth, parasite infections, leaky gut, and other digestive disorders can be easily detected.


Small Intestinal Bacterial Overgrowth (SIBO) is a disorder that occurs when there is an abnormal increase in bacterial population in the intestine tract, causing Inflammatory Bowel Disease. Our Functional Medicine doctors can detect this disease, and can also provide the right medication to help treating it.


Ulcers are lesions in the stomach and intestinal wall that might get irritated and become painful. The team of experts in digestive health can efficiently treat your ulcers, and help you determine their cause in order to prevent them from happening again.

Genetic Gut Microbial Tests:

This type of tests allows us to identify the percentage of different kinds of microbes in the stomach. It will enable us to evaluate whether their ratios and levels are enough in order to have a healthy and balanced bowel movement.

Leaky Gut:

With Time, your gut lining might develop cracks or tears, causing substances and chemicals to pass through to the tissues below. By seeking the advice of Functional Medicine professionals, it is possible to improve your condition and repair your intestinal epithelium while adopting the appropriate approach.
