Gastroenteritis is relatively common in clinical settings, and its treatment is generally divided into dietary treatment and medication treatment. For dietary treatment, a clean and easily digestible diet is more appropriate. It is advisable to avoid intake of spicy and pickled foods such as coffee, alcohol, and even salted fish, etc. Of course, a standardized and regular diet is very important. For medication treatment, symptom-specific options can be chosen. For example, if a patient often experiences stomach pain, acid-reducing and stomach-protecting medications can be selected. If, besides stomach pain, the patient exhibits abnormal bowel movements such as increased frequency of stool, diarrhea, etc., medications that stop diarrhea, regulate intestinal flora, and relieve spasms can generally be chosen. Typically, we opt for a treatment course of one to two weeks to observe effects. If the effect is good, the dosage can gradually be reduced and combined with dietary adjustments to generally achieve a certain level of control. (Medication use should be under the guidance of a professional doctor.)
