16 in the Journal of Clinical Endocrinology & Metabolism, also found that the risk was lower in celiac disease patients who ate a gluten-free diet and whose intestinal tissue had begun to heal. “Our research confirmed that patients had a higher rate of hip fractures when tissue damage persisted over time,” study author Dr. Benjamin Lebwohl, of the Celiac Disease Center at the Columbia University Medical Center, said in a journal news release. “Sticking to a gluten-free diet is crucial for minimizing tissue damage and reducing the risk of a serious fracture that could cause other complications.” Celiac disease is an autoimmune disorder that affects about 1 percent of people in the United States, according to the researchers. People with the condition have an immune response in the small intestine when they eat the protein gluten, which is found in grains such as wheat.
