The main principles of treating acute gastroenteritis clinically are to stop vomiting, stop diarrhea, relieve spasms, replenish fluids, and rest in bed symptomatically. For mild cases, oral intake of dilute salt water can be used to replenish lost body fluids. If there is frequent vomiting or obvious dehydration, intravenous fluids are necessary to maintain water and electrolyte balance. Sensitive antibiotics should be used to treat intestinal inflammation, but it is important to prevent antibiotic abuse. With active treatment, the prognosis for acute gastroenteritis is generally good. After treatment, attention should also be paid to diet; avoid eating unclean food, and consume less raw, cold, and spicy foods, while also paying attention to personal prevention.
