Since the intestinal epithelium does not have functions such as secretion of gastric acid, intestinal chemosis may present with symptoms such as bloating, belching, lack of appetite, and early satiety. Gastroscopic manifestations include fluffy yellowish nodules, translucent mucosa, and flat punctate changes. Intestinal metaplasia is the replacement of gastric mucosal epithelium by intestinal epithelium, which is usually seen in chronic atrophic gastritis. 1. Symptoms: Due to the appearance of intestinal epithelium in the stomach, gastric acid cannot be secreted, etc., and it is not easy to be digested after eating, and gas is generated in the body, which may lead to symptoms such as abdominal distension and belching. Gastric emptying is slowed down, which affects eating, and symptoms such as lack of appetite and early satiety may occur. 2. Endoscopic manifestations: there are single or multiple small yellowish nodules, protruding from the mucosal surface, showing a velvety appearance. Sometimes the mucosal surface is seen to be smooth and translucent, with thinning of the mucosa. Flattened punctate or squamous changes, etc. may also be seen. The gold standard for diagnosing intestinal chemosis is tissue biopsy. If intestinal chemosis is suspected, it is also necessary to perfect the examination under the guidance of doctor to make a clear diagnosis and carry out standardized treatment in time so as to avoid cancerous transformation. Avoid drinking alcohol, so as not to aggravate the damage of gastric mucosa, and pay attention to the light diet.
