It is currently believed that Helicobacter pylori infection is closely related to gastritis activity, ulcer formation, and tumors. Therefore, the main cause of gastric ulcers is the infection of Helicobacter pylori. Other factors, such as drugs, long-term use of non-steroidal anti-inflammatory drugs or steroid medications, often lead to gastric mucosal damage and result in peptic ulcers. Psychological factors, such as long-term excessive tension or high stress, often lead to peptic ulcers as well. Poor dietary and living habits, such as excessive drinking, consuming raw, irritating, greasy food, or binge eating, also promote the occurrence of peptic ulcers.
