In cases of childhood diarrhea, it is crucial first to identify the cause. Generally, it is categorized into infectious and non-infectious diarrhea. If it is suspected to be infectious diarrhea, it can be further divided into viral enteritis, bacterial infections of the intestines, and possibly fungal enteritis, among others. Typically, viral enteritis has a self-limiting course and does not require special medication treatments. The primary treatment includes hydration and maintaining electrolyte balance, and possibly using probiotics to regulate the intestinal flora as symptomatic treatment. If bacteria infection causes the enteritis, sensitive antibiotics are required for the infection. For non-infectious diarrhea, specific medications targeting the cause of the condition are used, such as lactase supplements for diarrhea caused by lactose intolerance and providing special formula milk for diarrhea. If the diarrhea is due to allergies, it's essential to avoid the allergens in the diet. Therefore, every case needs to be analyzed based on its specific circumstances. (Medication should be administered under the guidance of a professional doctor.)
