The drug treatment for acute gastroenteritis should be based on the specific cause. If it is a viral infection that causes gastroenteritis, it can generally be treated with oral antiviral drugs and astringent antidiarrheal drugs to achieve good therapeutic effects. If it is caused by improper food intake and bacterial infection, it usually requires the use of antibacterial drugs, such as cephalosporins or quinolones for anti-inflammatory purposes. If diarrhea is severe, appropriate antidiarrheal drugs can be taken for symptomatic treatment. At the same time, attention should be paid to a light and easily digestible diet, avoiding raw, greasy, spicy food and alcohol, which can generally relieve symptoms gradually.
