The treatment of gastroenteritis primarily depends on the cause and specific symptoms to determine the treatment plan. Exposure to cold or improper diet may cause acute gastroenteritis. In such cases, it is recommended to first check routine blood tests, C-reactive protein, stool routine, etc., to identify the cause. Gastroenteric flu can be treated with antiviral drugs and astringent antidiarrheal medications to achieve satisfactory results. Infectious diarrhea caused by bacterial infection generally uses antimicrobial drugs combined with antidiarrheal medications to also achieve satisfactory effects. Commonly used drugs include cephalosporins or quinolones anti-inflammatory. At the same time, it is important to pay attention to a light and easily digestible diet, and if diarrhea is severe, infusion treatment may be necessary to prevent dehydration.
