Lactose intolerance occurs when the body cannot digest the lactose in milk. Children with lactose intolerance have symptoms of bloating, flatulence, and persistent diarrhea. This condition recurs and causes intestinal dysbiosis, malabsorption, and slow growth in children.

For many people, fresh milk and dairy products have become essential in the daily diet. However, for some people who are allergic to Lactose in milk, a small glass of milk can cause digestive disorders with symptoms such as vomiting, diarrhea and abdominal pain. Therefore, the solution to this allergy is to use lactose-free milk products.
