Gastrointestinal care and treatment

Gastroenterologists are specialists in the disorders and diseases that affect the digestive system, including the gastrointestinal tract (esophagus, stomach, small intestine, large intestine, rectum, and anus) and the pancreas, liver, bile ducts, and gallbladder.

ARC gastroenterologists also perform screenings for colorectal cancer and other health issues, including performing upper endoscopy and colonoscopy.

Finding the right treatment for your G.I. tract

Persistent or regular abdominal discomfort or heartburn symptoms aren’t normal and can indicate a more serious condition.

Some of these serious, long-term conditions might include celiac disease, diverticulitis, diverticulosis, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), or inflammatory bowel disease. A consultation with an ARC gastroenterologist can help to diagnose your symptoms and develop a treatment plan to improve your gut health.
