Gastroenterology is the branch of medicine devoted to care of patients with diseases and disorders of the digestive system, including the esophagus, stomach and intestines.

Gastroenterologists specialize in treating the following conditions:

  • Gastroesophageal Reflux Disease (GERD) 
  • Inflammatory Bowel Disease (IBS)
  • Crohn's Disease
  • Ulcerative Colitis
  • Liver Disease
  • Chronic Constipation

The PeaceHealth Medical Group has a dedicated suite of physicians and nurses located in the Cordata building offering comprehensive endoscopic services, including the following screening and diagnostic procedures:

  • Colonoscopy
  • Esophagogastroduodenoscopy (EGD)
  • Flexible sigmoidoscopy
  • PillCamTM Capsule Endoscopy

When should you consider a colonoscopy?

Colon screening is an important part of preventive health care.  Primary risk factors for the development of colon cancer are age greater than 50 years, a family history of colon cancer, or a personal history of adenomatous polyps.  Even if you don't have a family history of colon cancer or a personal history of colon polyps, you should still be screened after age 50, and then at regular intervals in the future. Additionally, if you have any symptoms involving blood in the stool, diarrhea or constipation, you should undergo a diagnostic colonoscopy.
