(1) Tumor of digestive tract: gastric tumors, such as gastric mesenchymal tumors, gastric adenocarcinoma, etc., the tumor tissue can infiltrate into the submucosal layer of the stomach or even the muscular layer, and it can break through the basement membrane and grow outwardly or into the gastric lumen, and the encroachment of the tumor tissue into the peripheral tissues can cause gastric protrusion.
(2) Gastrointestinal polyps: when gastric polyps are at the bottom of the stomach, due to the occupying effect of the polyps can cause gastric bulge, and the gastric mucosa can be seen to have localized bulging during gastroscopy.
(3) indigestion: gastrointestinal dysfunction, peptic ulcer and inflammation and other diseases, can cause gastrointestinal digestive function decline, slow peristalsis, accumulation of food in the digestive tract fermentation gas production, thus causing abdominal distension, so that the stomach from the appearance of the bulge.
There are many other causes of gastric bulge, such as pyloric obstruction and other diseases, it is recommended to consult a doctor for a clear diagnosis.
