Patients with lactose intolerance can have multiple bowel movements per day after consuming milk; a mild case can result in 3-4 bowel movements, while severe cases might lead to dozens, potentially causing dehydration and electrolyte imbalance. For lactose-intolerant patients who need to consume milk, it must be specially treated beforehand. Additionally, if diarrhea is caused by poor digestion in the gastrointestinal tract, certain medications that adjust the gut microbiota can be used to aid digestion, such as Bifidobacterium triple viable bacteria and Bacillus cereus, etc. If the diarrhea is caused by allergies, allergen testing should be conducted. (Please use medication under the guidance of a doctor.)
