If you have any of the following symptoms it could be a sign that you have gluten intolerance:
Digestive issues such as gas, bloating, diarrhea and even constipation. I see the constipation particularly in children after eating gluten.
Keratosis Pilaris, (also known as ‘chicken skin’ on the back of your arms). This tends be as a result of a fatty acid deficiency and vitamin A deficiency secondary to fat-malabsorption caused by gluten damaging the gut.
