Brief Summary

In obese patients, the prevalence of obstructive sleep apnea (OSA) is around 40% in men and 30% in women. Weight loss after bariatric surgery significantly improves OSA, with 75% of patients having a reduction in OSA severity or becoming non-apneic. We hypothesize a similar effect on OSA of nutritional and psychocomportemental rehabilitation for obese patients. However, we expect weight loss and blood pressure reduction to probably be lower in obese patients who have OSA and nutritional rehabilitation alone than in those who are treated for their OSA or are without OSA. To address this question, we will conduct an observational study on obese patients, treated or not for OSA, following nutritional and psychocomportemental rehabilitation.
