High gastric acid secretion: frequent overeating, intake of greasy and indigestible food, taking strong tea and coffee, and stimulation of mental factors may lead to increased secretion of gastric acid, resulting in an obvious burning sensation. 3. Damage to the mucosa of the gastrointestinal tract: diseases such as gastritis, gastric ulcer, duodenal bulb ulcer, and reflux esophagitis lead to damage to the gastric mucosa and increased secretion of gastric acid. Gastric acid causes irritation to the site of the lesion, resulting in a burning sensation in the epigastrium. 4. Gastrointestinal perforation: Gastrointestinal perforation, especially gastric perforation, a large amount of gastric acid into the abdominal cavity, resulting in the abdominal cavity tissues and organs corroded by gastric acid, which can cause burning pain in the whole abdomen.
