Gastroenterology (Stomach/Intestine)

Gastroenterologists diagnose and treat a wide range of problems faced by those with stomach and intestinal issues.

We provide you with expert care in treating abdominal pain, gallstones, ulcers, abnormal bowel movements, heartburn, indigestion, hepatitis and diseases of the liver, pancreas and gallbladder. We also perform screenings for colorectal cancer.

Working in collaboration with primary care physicians and surgical specialists, our gastroenterologists offer patients a wide array of medical and surgical options to meet their needs. All screenings, procedures and surgical services are performed at Exeter Hospital.

Exeter Hospital’s Endoscopy Unit is one of only two hospitals in New Hampshire that has received a quality recognition from the American Society for Gastrointestinal Endoscopy (ASGE).
