Gastric ulcer

Gastric ulcer is a type of peptic ulcer, which is a chronic ulcer that occurs in the stomach and duodenum. It is a frequently-occurring and common disease. There are various factors for the formation of ulcers. The digestive effect of acidic gastric juice on the mucosa is the basic factor for ulcer formation. Wherever acidic gastric fluid comes into contact, such as the lower esophagus, anastomosis after gastrointestinal anastomosis, the jejunum, and Meckel's diverticulum with ectopic gastric mucosa, most ulcers occur in the duodenum and stomach, so it is also called stomach / ten Duodenal ulcer. Among them, delayed gastric emptying and bile reflux, abnormal effects of gastrointestinal peptides, genetic factors, drug factors (such as aspirin, many anti-inflammatory and painkillers, etc.), environmental factors and mental factors are all related to the occurrence of gastric ulcers. The main manifestations are upper abdominal dull pain, dull pain, swelling pain, burning-like pain or hunger-like pain. About 10% of the population has suffered peptic ulcers in their lifetime. The disease can be seen at any age, mostly in the 20-50 age group, with more men than women.
