Gastrointestinal disorders, as the name implies, are functional abnormalities or inflammation of the stomach and intestines, and also include diseases such as ulcers and tumors. Usually chronic gastrointestinal disorders do not necessarily occur at the same time, but can simply manifest as chronic gastritis, gastric ulcers and stomach tumors, with symptoms such as abdominal pain, bloating, belching and acid reflux. Chronic enteritis, on the other hand, mostly occurs in the colon and is prone to bloating, diarrhea, mucus stools, pus and blood stools, etc. The common ones are ulcerative colitis, chronic dysentery, amoebic dysentery, and colon cancer. Acute gastrointestinal diseases mostly affect both the stomach and intestines, and synthetic gastroenteritis, which usually occurs after eating raw and cold foods and unclean foods, usually starts with abdominal pain, bloating, nausea and vomiting, followed by frequent diarrhea. If the pathogen is more virulent, vomiting and diarrhea can occur at the same time, and some cases can be accompanied by fever.
