The only treatment for patients with CD is avoiding foods containing or made from wheat, barley, and rye for the rest of their lives. Eating even a small amount of gluten can damage the small intestine. In children, the small intestine usually heals within 3 to 6 months, but it may take years to heal in adults. Oats are safe in small amounts, although oats are often processed in facilities that also process other grains. Rice, potato, soy, and buckwheat are safe to eat. It is important for people with CD to read product labels, as gluten is used as an additive in some medications, lipstick, vitamins, and even Play-Doh.
