Acute gastroenteritis is usually caused by exposure to cold or improper diet, also known as gastroenteric cold or bacterial enteritis, with common symptoms including abdominal pain and diarrhea. The abdominal pain caused by gastroenteric cold is usually not very severe, and diarrhea is mainly watery. It often accompanies symptoms of upper respiratory tract infections, such as fever, chills, sore throat, and general body aches. Treatment mainly focuses on antiviral medications, combined with astringent hemostatic drugs, and a light diet is recommended. Bacterial enteritis caused by improper diet often leads to severe abdominal pain, and stools can be watery or mucous, and may even include pus and blood. The treatment for this condition primarily involves antibacterial therapy, such as cephalosporins or quinolones, and it is also important to maintain a light diet. (The use of medications should be under the guidance of a doctor.)
