Physiological factors: may be due to overeating, drinking on an empty stomach, excessive spicy stimulating food, long-term external factors or poor diet stimulation, easy to trigger a large amount of gastric acid secretion, stimulation of the gastric mucosa, which can lead to burning pain in the stomach. 2. Pathologic factors: (1) peptic ulcer: refers to the occurrence of chronic ulcers in the stomach, duodenum deep to the mucous membrane muscle layer, some patients can be asymptomatic, some patients may be due to excessive secretion of gastric acid to stimulate the ulcer site, resulting in burning pain in the stomach. (2) Acute gastritis: acute inflammation of the gastric mucosa due to microbial infection, physical or chemical stimulation, various stress reactions, etc., which can lead to hardness and pain in the stomach due to inflammatory stimulation. (3) Chronic gastritis: most patients with chronic gastritis do not have obvious symptoms, while a few patients with chronic gastritis may suffer from indigestion. Due to long-term stimulation of the gastric mucosa by chronic inflammation, indigestion may occur, resulting in excessive gas production, leading to burning and pain in the stomach, which may be accompanied by symptoms such as loss of appetite.
