Peptic Ulcers (Stomach and Duodenal Ulcers)
View or Print All Sections
A peptic ulcer, or stomach or duodenal ulcer, is a sore on the lining of your stomach or duodenum. Peptic ulcers can lead to complications such as bleeding, perforation, penetration, or blockage in your stomach or duodenum.
Common symptoms of peptic ulcers include pain or discomfort in your abdomen, feeling full too soon during or too full after a meal, nausea, bloating, and belching. The most common causes of peptic ulcers are Helicobacter pylori (H. pylori) infection and nonsteroidal anti-inflammatory drugs (NSAIDs).
Your doctor may ask about your medical and family history, perform a physical exam, and order tests to diagnose a peptic ulcer, find its cause, and check for complications. Doctors may order tests to check for Helicobacter pylori (H. pylori) infection, upper gastrointestinal (GI) endoscopy, and upper GI series.
Doctors may recommend medicines to heal peptic ulcers and will look for and treat the underlying cause. Doctors treat Helicobacter pylori (H. pylori) infection with medicines. If you have a peptic ulcer due to taking nonsteroidal anti-inflammatory drugs (NSAIDs), your doctor may change your medicines.
Researchers have not found that diet and nutrition play an important role in causing, preventing, or treating peptic ulcers. Doctors do not recommend following a special diet or avoiding specific foods or drinks to treat or prevent ulcers.
The NIDDK conducts and supports clinical trials in many diseases and conditions, including digestive diseases. The trials look to find new ways to prevent, detect, or treat disease and improve quality of life.
The digestive system is made up of the GI tract—also called the digestive tract—and the liver, pancreas, and the gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
