Fever from food accumulation is manifested by digestive symptoms such as dry stools, bloating, abdominal pain, belching, bad breath, decreased appetite, etc., and fever symptoms such as body temperature below 38.5 degrees, coughing. 1. Digestive tract symptoms: (1) Dry stools: the burden on the gastrointestinal tract is increased, and the peristalsis of the gastrointestinal tract is slower, resulting in feces being retained in the intestinal tract, and the stools become dry and not easy to be discharged. (2) Bloating and abdominal pain: too much food accumulates in the stomach and is not emptied in time, resulting in bloating and abdominal pain. (3) Belching: Belching is caused by increased gas production when food stays for a long time. (4) Bad breath: the food in the stomach is difficult to digest and the gas produced by abnormal fermentation leads to bad breath. (5) Loss of appetite: the food in the stomach can not be emptied in time, resulting in bloating, no hunger and do not want to eat. 2. Fever symptoms: the temperature does not rise much, usually below 38.5 degrees accompanied by abdominal distension, abdominal pain and other symptoms.
