What is often the first sign of celiac disease in children?

The first sign of celiac disease in children is often diarrhea and flatulence. This condition stems from an adverse reaction to gluten, a protein found in wheat, barley, and rye. When children with celiac disease consume gluten, it leads to inflammation in the small intestine, which impairs nutrient absorption and disrupts normal gastrointestinal function. This usually results in the characteristic symptoms of diarrhea and excessive gas as undigested food ferments in the intestines.

In the context of celiac disease, diarrhea can become chronic, and children may exhibit loose, watery stools. Flatulence may occur as the body struggles to digest gluten properly, leading to an accumulation of gas. Recognizing these gastrointestinal symptoms is crucial for early diagnosis and intervention, which can help mitigate further complications associated with untreated celiac disease.
