What causes a peptic ulcer?
Most peptic ulcers are caused by a bacteria (germ) in the stomach called Helicobacter (hel-i-ko-bak-ter) pylori. This bacteria is also called H. pylori. Certain medicines, such as nonsteroidal anti-inflammatory drugs (NSAIDs), may cause peptic ulcers. Some diseases or infections may increase your risk of having a peptic ulcer. These diseases increase acid in your stomach or decrease your stomach’s defense from acid. Other factors that may increase your risk of having a peptic ulcer are smoking, drinking too much alcohol, or eating certain foods. You may also be more likely to have a peptic ulcer if another family member has this disease. What are the signs and symptoms of a peptic ulcer? The most common symptom is a burning feeling or pain in your upper abdomen (stomach). This may occur 1 to 3 hours after eating or when you are hungry. The pain may wake you from sleep and may come and go for weeks to months. Other signs may be nausea (upset stomach), vomiting (throwing up), or burping.
