Acute gastroenteritis should be treated in the gastroenterology department of the hospital. Acute gastroenteritis is mostly caused by unclean food or excessive fatigue, with the main symptoms being abdominal pain and diarrhea, accompanied by signs of dehydration in the body. Treatment mainly involves the use of antibiotics to control the infection and antidiarrheal medications to treat diarrhea. It is important to promptly replenish fluids and water if there is significant dehydration. During treatment, a light diet should be maintained, eating small meals frequently, and avoiding spicy, stimulating, and greasy foods. (Medication should be used under the guidance of a doctor.)
