**7. Conclusions**

Bulimia nervosa is a common health problem in young people, has been reported worldwide both in developed regions and emerging economies, and its prevalence is arising. It can lead to serious medical complications. However, studies from the US and continental Europe suggest that only a fraction of people with bulimia receive specialised treatment for their eating disorder. The alimentary canal is the front line for the eating disorder patient. Therefore, the expression of the disease in the gastrointestinal tract may have a critical role in early diagnosis and management of the disease. New treatment strategies are now available, and evidence-based management of this disorder is possible. A specific form of cognitive behaviour therapy is the most effective treatment, although few patients seem to receive it in practice.
