Prospective study with inclusion of bariatric surgery candidates with diagnosed Obstructive Sleep Apnea and requiring treatment with Continuous Positive Air Pressure, aiming to evaluate at 2-6-12 months after bariatric surgery whether the relationship between biometric changes (reduction in neck circumference, height, waist/hip ratio, and fat and lean mass) and the resolution of OSA is better than the relationship between these biometric changes and BMI reduction.
eligible for bariatric surgery: with severe obesity (BMI≥35-40) or morbid obesity (BMI≥40), with co-morbidities, who have not lost enough weight with prior lifestyle adaptations (balanced diet, physical activity) AND
with diagnosed obstructive sleep apnoea (OSA) (AHI > 15/hr on polysomnography) AND
requiring treatment with Continuous Positive Air Pressure (CPAP)
Cognitive impairment - language barrier
Eligible patients from CHU St Pierre hospital setting
Case-only
Prospective
Bariatric surgery
Procedure/SurgeryBariatric surgery includes (but is not limited to) * Gastric bypass: surgical bypass of the entire stomach, duodenum and approximately 1 m of the proximal small intestine * Sleeve: a large part of the stomach is removed laparoscopically, the open vertical edges are put back in place to leave a sleeve-like tube. Bariatric surgery is considered a treatment option * for patients with a BMI \>40 kg/m 2 , assuming the patient has previously participated successfully in a group weight management programme (weight loss \>7%) or * for patients with a BMI of 35-40 kg/m 2 when the obesity is associated with type 2 diabetes or hypertension, or OAS (with CPAP therapy) or severe musculoskeletal disease
