Diseases that can cause gastric distension and bloating include peptic ulcers, dyspepsia, digestive tract tumors, gastrointestinal neurosis, and intestinal obstruction. Peptic ulcers mainly include gastric ulcers and duodenal ulcers, which can affect the peristaltic ability of the intestines and stomach, resulting in a weakened peristaltic function and the accumulation of food in the digestive system causing bloating and abdominal distension. When indigestion occurs, the peristaltic function of the stomach will be weakened and the intestinal system will not be able to better absorb nutrients from food, resulting in the reaction of food residues in the intestine with undesirable bacteria and bloating and abdominal distention. Gastrointestinal tumors, mainly including gastric cancer and intestinal cancer, can damage the function of the digestive tract and affect human health at the same time. Most people with the disease will be accompanied by gastric distension and abdominal distension. The appearance of gastrointestinal neurosis is related to factors such as bad emotions and intestinal system allergies. During the disease, the function of the intestine and stomach will be disrupted, thus causing digestive distension. When there is an obstruction in the intestine, the contents of the intestine will gather in the intestine because it cannot be unblocked, thus also causing gastric distension and abdominal distension.
