Patients with Obstructive Sleep Apnea (OSA) face a significantly increased risk of major perisurgical adverse outcomes and perioperative death when undergoing bariatric surgery.
Having sleep apnea makes weight loss surgery much more dangerous. It triples your risk of dying during the procedure. This is why doctors require a sleep study before surgery.

- Polysomnography (PSG) is an essential component of the preoperative workup for patients undergoing bariatric surgery because clinical parameters (BMI, neck circumference, Epworth Sleepiness Scale) are inadequate predictors of Obstructive Sleep Apnea (OSA).Good
- Obstructive Sleep Apnea (OSA) is significantly underdiagnosed in patients undergoing bariatric surgery, with only 13.3% of patients having a prior diagnosis despite a 69.9% prevalence rate.Good
