Gastric ulcers refer to inflammatory defects in the gastric mucosa, with several common causes as follows: First, infection with Helicobacter pylori is directly related to the development of peptic ulcers. Second, various drugs that damage the gastric mucosa, such as non-steroidal anti-inflammatory drugs, corticosteroid hormones, etc. Third, dietary factors. Long-term alcohol consumption, spicy foods, strong tea, and coffee can all cause gastric ulcers. Fourth, the digestive actions of gastric acid and pepsin damage the gastric mucosa, leading to a decline in the protective barrier function of the mucosa and causing ulcers. Fifth, abnormalities in gastric motility and decreased emptying ability, leading to food retention in the stomach, continuously irritating the gastric mucosa, causing increased gastric acid secretion and resulting in ulcers.
