The preliminary diagnosis of stomach bulge is caused by gastrointestinal flocculation, because the symptoms of functional flocculation in the stomach, intestines and other digestive tract tissues will cause a decrease in their operational efficiency and ecological imbalance of flora. When food enters the digestive tract, it is not decomposed and absorbed in time, and it will have deep metabolic reactions with gas-producing bacteria such as Clostridium perfringens and methanogens, and produce a large amount of gas-like substances. As the emptying function of the gastrointestinal tract is blocked, the gas in the body cannot be discharged out of the body in time, which will cause forced expansion of the mucosa of the gastrointestinal tract, resulting in symptoms such as flatulence, belching and acid swallowing, and loss of appetite. However, the possibility of organic lesions in the stomach, such as Helicobacter pylori infection, gastrinoma, bile reflux gastritis, etc., cannot be ruled out, but in contrast to the former, patients with these diseases will not only have stuffy and distended stomach, but also have significant stomach pain, nausea, vomiting and other complications.
