Where does ulcers come from?

Ulcers are open sores that can develop on the skin or mucous membranes, commonly occurring in the stomach (gastric ulcers) or the small intestine (duodenal ulcers). They are primarily caused by an infection with the bacterium Helicobacter pylori, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, and stress. Factors like smoking and a diet high in spicy foods can also contribute to their development. Treatment typically includes antibiotics, acid-reducing medications, and lifestyle changes.
