Acute gastroenteritis is primarily an acute inflammation of the gastrointestinal mucosa. It is mainly characterized by symptoms such as nausea, vomiting, diarrhea, and fever, and is commonly seen in the summer and autumn seasons. It is primarily caused by improper diet, overeating, or consumption of raw, spoiled, or unclean food. The condition is mainly due to bacterial or toxin infection, often seen in group outbreaks or family clusters. It can be caused by the consumption of infected fish, meat, poultry, or seafood, or by leftovers contaminated with Staphylococcus aureus, among others. Moreover, accidental ingestion of strong acids, strong alkalis, or certain pesticides can also cause this disease.
