Peptic ulcer is a common gastrointestinal disease, and the primary cause should primarily be Helicobacter pylori infection. Extensive research has proven that Helicobacter pylori infection is closely related to gastric inflammation activity, the formation of peptic ulcers, and gastric cancer. Secondly, drugs are a factor; many drugs can damage the gastric mucosa, such as non-steroidal anti-inflammatory drugs and corticosteroids, which often lead to the occurrence of peptic ulcers. Additionally, mental stress is often a catalyst for stomach diseases, with numerous studies showing that a person's emotions, personality, and mental stress are related to peptic ulcers. Furthermore, poor dietary and living habits can also damage the gastric mucosa, leading to the occurrence of peptic ulcers.
