Why to Avoid Lactose Diet During Children’s Diarrhea

Question

My son had some diarrhea a few days ago, and he still wasn’t feeling better today, so we went to the hospital. The doctor said to stop eating foods containing lactose. Why should we avoid lactose during children’s diarrhea?

Answer

It is important to avoid lactose-containing foods during children’s diarrhea because lactose intolerance or milk allergy can cause diarrhea and lead to persistent symptoms. Additionally, milk allergy may damage the lactase enzyme on the intestinal mucosa, causing lactose intolerance. Lactose is a sugar found in milk, and some people do not produce enough lactase to digest lactose, leading to digestive system symptoms.
