Fever due to food accumulation can be caused by gastrointestinal dysfunction, gastritis, bad dietary habits, etc. It can be treated with gastric stimulants such as mosapride and antipyretics such as ibuprofen. Accumulated food refers to the failure of timely digestion of food in the gastrointestinal tract leading to indigestion, usually caused by gastroduodenal dysfunction, insufficient secretion of gastric acid, Helicobacter pylori infection, overeating and drinking. Common symptoms include bloating, stomach pain, belching, nausea and vomiting, etc. In severe cases, fever may occur due to the accumulation of endotoxin. Fever due to food accumulation usually requires medication to promote gastric motility, such as mosapride and domperidone, to promote gastrointestinal smooth muscle motility; if necessary, cecrops can also be used to promote laxative effect; if fever persists, antipyretic medication such as ibuprofen can be used. Gastric stimulants (e.g. domperidone) and antipyretics (e.g. ibuprofen) may have side effects such as bloating, nausea and vomiting, and neurological symptoms such as dizziness and headache may occur with ibuprofen. The occurrence of food accumulation and fever, it is recommended to go to a regular hospital in a timely manner, under the guidance of a professional doctor to use medication, so as not to delay the condition.
