Acute gastroenteritis generally occurs more frequently in the summer and autumn seasons, possibly due to exposure to cold or improper diet, typically presenting with symptoms such as abdominal pain, diarrhea, vomiting, bloating, and even fever and chills. Relevant tests, such as a complete blood count, C-reactive protein, and stool examination, can usually confirm the diagnosis. As for treatment, it depends on the cause, such as anti-inflammatory, antiviral, antidiarrheal, and rehydration measures. Most cases of acute gastroenteritis can be completely cured. During treatment, it's necessary to control the diet by consuming light, easily digestible foods, such as porridge and soft noodles, and to avoid raw, greasy, or spicy foods that might provoke recurring episodes. (Specific medications should be used under the guidance of a doctor.)
