Diagnosing and treating digestive conditions


From treating heartburn to preventing colon cancer, Geisinger’s gastroenterologists use advanced tools and state-of-the-art techniques to diagnose and treat digestive conditions.

By using a variety of endoscopes (small, flexible, lighted tubes with built-in cameras) and other tools, our doctors can diagnose and treat patients without performing surgery, often in a single visit.

What you should know about gastroenterology

  • Our gastroenterologists treat a full range of conditions from simple to complex, including:
    • Heartburn or acid reflux
    • Trouble swallowing
    • Ulcers
    • Abdominal pain
    • Constipation
    • Diarrhea
    • Rectal bleeding
    • Anemia
    • Weight loss
    • Liver problems (hepatitis and cirrhosis)
    • Gallstones and other gallbladder problems
    • Chronic pancreatitis and pancreatic cancer
    • Pancreatic cysts
    • Inflammatory bowel disease (Crohn's disease or ulcerative colitis)
    • Family history of gastrointestinal cancers
    • Celiac disease and nutritional problems
  • A colonoscopy is the most effective screening tool for colon cancer. The American Cancer Society recommends colonoscopy for people age 50 and older who are at average risk for colon cancer. Screening is recommended for people younger than 50 if they have a family history of colon cancer.
