Research suggests that celiac disease only occurs in people who have specific genes. These genes are common and are carried by about a third of the population. People also have to eat foods containing gluten to develop coeliac disease. Researchers do not know exactly what triggers celiac disease in at-risk people who eat gluten over a long period of time. Sometimes the disease runs in families. About 10-20% of close relatives of people with celiac disease are also affected.

Your chances of developing coeliac disease increase when you have changes in your genes or variants thereof. Certain gene variants and other factors, such as environmental factors, can lead to celiac disease.
