Peptic ulcers are sores on the GI tract lining caused by H. pylori infection or NSAID intake. Stress, smoking, and alcohol can aggravate symptoms. Antibiotics are used to treat ulcers caused by H. pylori.
Peptic ulcers are sores on the tissues lining the esophagus, stomach, or duodenum caused by damage to the mucous coating, exposing the tissue to pepsin and hydrochloric acid. The most common cause is infection with the bacterium Helicobacter pylori or excessive intake of non-steroidal anti-inflammatory drugs (NSAIDs).
Peptic ulcers are also influenced by factors like stress, smoking, and alcohol, which can worsen symptoms but do not directly cause the ulcers themselves.
Doctors used to believe stress and stomach acid caused ulcers until the discovery of the role of H. pylori, which led to effective antibiotic treatments.
