Multi-Specialty Clinic

The Multi-Specialty Clinic provides Gastroenterology (Digestive Health) and General Surgery services. The clinic is located in UnityPoint Health – Meriter hospital on the second floor (main level).


Gastroenterology is the branch of medicine that focuses on the health of the digestive tract, including the esophagus, stomach, small intestine, colon or large intestine, rectum and anus, liver, pancreas and biliary tract.

Physicians who specialize in the treatment of digestive disorders are called Gastroenterologists. Meriter's Gastroenterology team treats such conditions as Barrett's Esophagus, Celiac Disease, Crohn's Disease, Diverticular Disease, Gastritis, Gastroesophageal Reflux Disease (GERD)/Heartburn, Hepatitis, Irritable Bowel Syndrome (IBS), Peptic Ulcers and Ulcerative Colitis.

Our physicians treat patients in either the Multi-Specialty Clinic or the Digestive Health Center, also located with UnityPoint Health – Meriter hospital.

It focuses on abdominal organs and their diseases, including the esophagus, stomach, small bowel, colon, liver, pancreas, gallbladder, appendix, spleen and thyroid, parathyroid and adrenal glands.

Surgeons also perform vasectomies and deal with diseases involving the skin, breast and hernias.
