If the patient has gastroenteritis, we recommend that the patient should rest in bed as much as possible. For patients with mild conditions, we can advise oral intake of glucose and electrolytes to replenish the loss of body fluids. If there is persistent vomiting or evident dehydration, intravenous rehydration with glucose saline and other relevant electrolytes is necessary. We encourage the intake of light liquid or semi-liquid diet to prevent or treat mild dehydration. Additionally, injections of pain relievers, antispasmodic drugs, and antidiarrheal medications can be administered for symptomatic treatment. For infectious diarrhea, targeted antibiotics can be used, but it is advised to avoid their misuse.
