Digestive Diseases

The human digestive system is a complex network of tubes and specialized organs. Its essential function is to digest food, extract nutrients from food to nourish the body, and dispose of waste. The digestive system is always at work, so it’s not uncommon for problems to occur. In fact, between 60 and 70 million people suffer from digestive diseases.


Digestive Health for Our Community

Gastroenterologists, commonly called GI doctors, are experts in treating all things related to the digestive system. GI doctors diagnose and treat disorders affecting the small bowel, colon, and organs that impact digestion, including the stomach, intestines, liver, pancreas, and gallbladder. From celiac disease to ulcers, the specialized team at UT Health North Campus Tyler has years of experience in keeping our patients’ digestive systems in check.
