What is a significant risk associated with untreated lactose intolerance in children?

Untreated lactose intolerance in children can lead to significant nutritional deficiencies, particularly if they avoid dairy products without finding suitable alternatives. Lactose intolerance can cause gastrointestinal symptoms such as bloating, diarrhea, and abdominal pain when lactose is consumed. These symptoms might lead to a reduction in food intake and avoidance of important nutritional sources, specifically calcium and vitamin D, which are crucial for bone development and overall growth.

When children do not receive adequate nutrition, particularly during critical growth periods, this can result in delayed growth and development. This can manifest not only in physical growth but also in cognitive and emotional development, leading to long-term implications for health and well-being.

While dehydration is a possible concern due to the diarrhea that may accompany lactose intolerance, the primary risk associated with untreated lactose intolerance is inadequate nutrient absorption, which directly affects growth and development. Thus, addressing lactose intolerance effectively is essential for ensuring that children receive the necessary nutrients for healthy growth.
