The treatment methods for gastroenteritis mainly include general treatment and drug treatment. General treatment means that patients should pay attention to rest and keep warm to avoid catching cold in the abdomen. They can also use hot compresses to relieve symptoms and cooperate with physical therapy methods such as acupuncture and moxibustion. Effective drug treatment should also be applied. For infections caused by certain pathogens, anti - infective drugs are needed. For gastroenteritis caused by parasitic infections, anti - parasitic drugs are required. Attention should also be paid to replenishing fluids to prevent dehydration and appropriately supplementing electrolytes. In addition, symptomatic and supportive treatment should be strengthened. Most patients have a good prognosis. Only a very small number of patients may develop serious complications.
