[Long-term management after bariatric surgery].

The number of bariatric surgery interventions has increased over the past 10 years. The effectiveness of bariatric surgery is currently well demonstrated. However, the need to organize a careful medical follow-up of these patients is essential to ensure a positive evolution over the long term. In fact, weight change may be highly variable : excessive weight loss, early stabilization, progressive weight recovery in the middle or long term, all events that often require a multidisciplinary approach.

In absence of adequate management, such complications may hinder the success of surgery. This article describes the most important points of long-term medical follow-up of patients who underwent bariatric surgery.
