Digestive Health

HomeServicesDigestive Health

Gastroenterology concerns issues with your colon, pancreas, liver, gallbladder, esophagus and stomach. A gastroenterologist diagnoses and treats problems with these organs and their function. This includes movement of material through the stomach and intestine, the function of the liver, digestion and absorption of nutrients into the body, and removal of waste from the system. 

The Digestive Health Institute, working collaboratively with Kalispell Gastroenterology, is the largest gastrointestinal (GI) medical group in Montana and a regional destination for high-value GI health care. Our adult and pediatric gastroenterology specialists treat a full range of simple to complex GI conditions.
