The trial is looking for adults who are candidates for weight-loss (bariatric) surgery and have obstructive sleep apnoea that needs CPAP treatment.
- Age
- 18 to 99 years
- Sex
- All sexes can join.
- Disease stage
- Severe obesity (BMI 35-40) or morbid obesity (BMI 40 or more) with other health problems, and obstructive sleep apnoea with AHI above 15 per hour on a sleep study.
- Earlier treatment
- Lifestyle changes such as a balanced diet and physical activity did not lead to enough weight loss. Must need CPAP treatment.

- Original description
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.Read full original descriptionShow less
Changes in Body Fat and Morphologic Characteristics Associated With Obstructive Sleep Apnea (OSA) Resolution After Bariatric Surgery
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.
Inclusion: Any informed person who is; 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).
Exclusion: Cognitive impairment - language barrier.
