Celiac disease and health-related quality of life.

Celiac disease is a particularly common life-long disorder with a prevalence of approximately 1-2% in Western populations. In recent years the health-related quality of life has become an important issue in this context, and most studies carried out so far have shown diminished quality of life in untreated patients compared with healthy controls. Furthermore, there has generally been a beneficial response to treatment with a gluten-free diet. However, the majority of trials have been carried out among adults with gastrointestinal disease, while in fact several extraintestinal and atypical forms of celiac disease might be even more common than the classical disorder. In addition, only a small proportion of these studies have been conducted among children. This article highlights the studies of health-related quality of life and celiac disease conducted to date. Particular attention is paid to the extraintestinal and atypical forms of the disorder.
