Impact de la chirurgie bariatrique sur la santé et la qualité de vie du patient obèse [Impact of bariatric surgery on health and quality life of obese patients]

The important weight loss due to bariatric surgery allows to improve and even correct, a great part of the comorbidities induced by obesity, as well as quality of life, and to reduce the coming out of cardiovascular and metabolic diseases in operated patients. The impact of surgical treatment on the patient's health and quality of life also allows to reduce direct and indirect costs of morbid obesity. However, its effects on mortality have not yet been clearly proved. The preoperative evaluation and the long term follow-up by a skilled team are essential to reduce potential complications, especially on the nutritional field and the risks of recovered weight linked to binge eating disorders.

L'apport de CoLaus en santé publique [What CoLaus has brought to public health].

In order to fulfil their duties, Public health authorities have to rely on valid and recent data on the health status of populations. The CoLaus study helped to update our knowledge regarding the prevalence and management of the main cardiovascular risk factors in the Lausanne population. The results indicate that cardiovascular risk factor management is suboptimal and can still be improved, namely that specific population subgroups could benefit from targeted prevention measures. The CoLaus study also allowed to simulate the effect of different preventive strategies, thus enabling to choose the most (cost) effective ones, an important issue taking into account the current health budget restrictions.
