Neurogastroenterology Diseases Program

The Neurogastroenterology Diseases Program at Houston Methodist Lynda K. and David M. Underwood Center for Digestive Disorders improves the health and lifestyles of patients suffering from gastrointestinal disorders caused by common and rare conditions. These include diabetes and scleroderma (hardening and tightening of the skin and connective tissues), as well as a group of very common disorders that affect the function of the gut (called functional gastrointestinal disorders), such as irritable bowel syndrome (IBS).

Neurological diseases such as Parkinson’s disease, multiple sclerosis and amyotrophic lateral sclerosis, better known as ALS or Lou Gehrig’s disease, also can affect gastrointestinal tract nerves, as well as muscles involving the esophagus, stomach, colon, small intestine and other parts of the digestive tract.

Patients Experience an Improved Quality of Life

Patients from Texas and around the country travel to our center for treatment. Many have suffered for years from conditions that prevented them from working and reduced the quality of their lives.
Eamonn Quigley, David M. Underwood Chair of Medicine in Digestive Disorders, had a patient tell him, “You’re my last hope, Doctor.” “We can help them,” he said. “A lot of them are people who have tried a lot of things. They’ve tried over-the-counter stuff. They’ve tried alternative routes and diets. Nothing works. If you listen to people and really care for them, you can make a difference.”
