A startling study has just been published that confirms a strong genetic link between celiac disease and type 1 diabetes. In both diseases, the immune system mistakenly attacks healthy cells. In diabetics the insulin-producing cells of the pancreas are the target, while in celiacs the small intestine is attacked and inflamed. While scientists have known before that people with type 1 diabetes are much more likely to have celiac disease and vice versa, the new study shows that the diseases share a genetic link of at least “seven chromosomal regions.” This information brings scientists closer to understanding the triggers and underlying causes of both diseases. All you need to know? If you suffer from celiac disease or type 1 diabetics, it would be wise to be fully aware of the symptoms and treatments of the other disease.
