Coeliac disease is more likely to be diagnosed in other family members. As a small child, daughter Cerys had no interest in food. She had bouts of diarrhoea, her stomach began to swell, her growth slowed. It was several years before they were asked about a family link to coeliac disease. This question opened the door for further investigations resulting in a confirmation of severe untreated coeliac disease. If we can learn more about the condition occurring in families then maybe we can learn how to stop it from happening altogether.
