The most common cause of stomach ulcers, or gastric ulcers, is an infection with the bacterium *Helicobacter pylori* (H. pylori). Other significant causes include the long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen, excessive alcohol consumption, and smoking. Stress and spicy foods were once thought to be major causes, but they are now considered less significant in the development of ulcers compared to these other factors.
