Celiac Disease in Children: Signs, Diagnosis, and Managing Gluten Exposure

When a child has celiac disease, an autoimmune disorder triggered by gluten that damages the small intestine. Also known as gluten intolerance, it’s not just a stomach issue—it stops nutrients from being absorbed, which can slow growth, cause fatigue, and even affect mood and behavior. Unlike a food allergy, celiac disease doesn’t cause immediate hives or breathing trouble. Instead, it quietly eats away at the lining of the gut, making even small amounts of wheat, barley, or rye dangerous over time.

Many kids with celiac disease, an autoimmune disorder triggered by gluten that damages the small intestine. Also known as gluten intolerance, it’s not just a stomach issue—it stops nutrients from being absorbed, which can slow growth, cause fatigue, and even affect mood and behavior. go undiagnosed for years because symptoms vary so much. Some children have classic signs like chronic diarrhea, bloating, or vomiting. Others barely have digestive problems at all—instead, they’re short for their age, have delayed puberty, or get frequent headaches. Dental enamel defects and unexplained anemia are also red flags. If your child seems tired all the time, isn’t gaining weight like other kids, or has strange skin rashes, celiac disease might be the hidden cause. Testing starts with a simple blood screen for antibodies, but a biopsy of the small intestine is still the gold standard for confirmation.

Many parents worry about their child feeling left out, but today’s gluten-free options are better than ever. With the right support, kids can thrive—eating well, growing normally, and joining in without fear.
