Acute gastroenteritis is quite urgent and is characterized by significant nausea, vomiting, and diarrhea. The treatment principle involves bed rest and symptomatic use of antiemetic, antispasmodic, antidiarrheal, and rehydrating medications. For milder cases, oral rehydration solutions can be consumed. If persistent vomiting occurs with obvious dehydration, it is timely to administer intravenous fluids to replenish relevant electrolytes, and, if necessary, inject drugs for antispasmodic and antiemetic purposes; For infectious diarrhea, sensitive antibiotics can be chosen. During treatment, it is important to drink water properly, eat vegetables, stay hydrated, eat smaller and more frequent meals, and avoid spicy and greasy foods.
