Acute gastroenteritis is characterized by symptoms such as vomiting, nausea, or diarrhea. If the diarrhea is severe, there can be significant bodily dehydration, manifesting as fatigue or dizziness. It is important to promptly replenish body fluids and undergo infusion therapy. At the same time, proactive use of antibiotics and antidiarrheal medications is advised. The general treatment period lasts 3-5 days. After recovery, attention should be given to dietary adjustments, incorporating fresh green vegetables. It is advisable to eat some fruit and have meals regularly and in controlled quantities, while reducing consumption of spicy, greasy, and irritating foods. Appropriate outdoor exercises should be performed to help regulate gastrointestinal function. (Please follow the doctor's advice regarding medication use.)
