However, many turn to a gluten-free diet for medical reasons and for relief of specific symptoms. It is estimated that roughly 10 percent of the population have gluten-related disorders.

Presenting signs and symptoms of pediatric celiac disease are varied, ranging from gastrointestinal symptoms such as abdominal pain, diarrhea or constipation to extraintestinal symptoms, such as low energy, poor growth or delayed puberty.

Positive celiac serology, such as tissue transglutaminase IgA and endomysial IgA, are typically excellent predictors of celiac disease diagnosis. However, it is important to remember that children without celiac disease can have positive test results. For this reason, small bowel biopsy via esophagogastroduodenoscopy (EGD) before starting a gluten free diet, is still the gold standard for diagnosing celiac disease. …Read More
