Dr. James Maher is board-certified in gastroenterology and internal medicine. His specializations in these areas include IBS, acid reflux, colon cancers, and other digestive health conditions. After his graduation from the Medical College of Virginia, Dr. Maher completed one residency and two fellowships at the University of California-Irvine.

During his years in practice at the Katy Stomach Doctor, Dr. Maher has earned respect among fellow physicians as one of the leading gastroenterologists in the Houston area. His patients have also given him recommendations in the Houston community, largely the result of the quality of compassion and care shown.

Whether that means attending a conference or lectures, Dr. Maher works hard to stay apprised of the newest medical practices and treatments. Furthermore, his dedication to educating patients about their condition and its management is, in part, what makes him a great physician.


The process of diagnosing your condition actually begins with an evaluation. During this consultation, your doctor will ask several questions about the duration, types, and intensity of your symptoms. Additionally, you might expect questions related to your lifestyle and work life.

Some digestive conditions might be considered normal when they follow specific activities. For instance, after a hearty workout, you might experience temporary abdominal pain. Or, after eating spicy food, heartburn may be a temporary issue for you. However, when these symptoms don’t go away, there might be cause for concern.

While the medical team at Katy Stomach Doctor could make an educated guess about the root cause of your symptoms, sometimes a diagnostic procedure is needed in order to pinpoint the cause.

The Katy Stomach Doctor team will offer you reliable advice about the evaluation, diagnosis, and treatment of your condition. You will leave our clinic feeling like you are able to overcome the symptoms and live a healthier life.

After your doctor has evaluated your condition, they might recommend a diagnostic procedure that helps them accurately pinpoint the issue. For example, if you are experiencing esophageal pain, trouble swallowing, or acid reflux, chances are your physician will request an Endoscopy.

This is a very common, easy and fast procedure that only takes about thirty minutes to complete. It begins when the patient is under anesthetic. The doctor will insert an Endoscope (tiny camera) into the patient’s mouth and down their throat. The Endoscope camera sends a video feed to a tv monitor in the procedural room.

Once the doctor has examined the inside of the patient’s esophagus and upper digestive tract, they will retract the tube. A biopsy can be taken if necessary.

This procedure has few risks associated with it. However, it is important to keep in mind you will experience side effects of the anesthesia for about twenty-four hours following the procedure. Therefore, it is ideal to ask a family member or friend to drive you home.


Once you have received a diagnosis concerning your condition, it is important to discuss the next steps with your doctor. When you come to Katy Stomach Doctor, you will find that we have a commitment to finding a treatment plan that is custom fit to the patient’s needs.

Typically, doctors will ask their patients to begin treatment with a lifestyle change. Whether this is in dietary habits or how much exercise you get, they will often make this a first step.

Additionally, medications can help alleviate symptoms while you begin treatment. The simplest lifestyle change can have a large positive impact on the way you feel on a day-to-day basis. Ask your doctor about treatment options that will help you get back to living a healthier life.
