For childhood indigestion and diarrhea, one can initially use intestinal probiotics to modulate the gut flora, such as Bifidobacterium or Lactobacillus. Additionally, zinc supplementation can be provided to promote the repair of the gastrointestinal mucosa. Another option is to administer Smecta to protect the gastrointestinal mucosa. Digestive medications can also be given, such as Chinese medicinal herbs like hawthorn, Shenqu, and malt to aid digestion. Furthermore, it is important to ensure the diet consists of easily digestible foods.
