By Kathryn Doyle (Reuters Health) – Girls diagnosed with celiac disease tend to be slightly shorter than their peers and boys to be underweight, but the size differences are not significant or concerning, Israeli researchers say. Celiac disease (CD) is an autoimmune disorder that damages the small intestine and interferes with the absorption of nutrients from food. The new study ultimately clarifies that regardless of gluten-free diet adherence, body measurements at late adolescence including final height are only marginally affected, said lead study author Dr. Amit Assa of Tel-Aviv University.
