For the treatment of gastroenteritis, the treatment plan should first be determined according to the cause and specific symptoms. Cold or improper diet may lead to acute gastroenteritis. In this case, it is recommended to check blood routine, C-reactive protein, stool routine, etc. to determine the cause. Gastrointestinal cold can be satisfied by using antiviral drugs and astringent antidiarrheal drugs. For infectious diarrhea caused by bacterial infection, antibacterial drugs are generally used, which can also achieve satisfactory efficacy in combination with antidiarrheal drugs. Common drugs such as cephalosporins or quinolones are anti-inflammatory. At the same time, attention should be paid to light diet and easy digestion. If the diarrhea is serious, infusion treatment is required to avoid dehydration.
