Obesity and sleep apnea

How are obesity and sleep apnea connected? Research suggests that sleep apnea:

  • Is highly prevalent in morbidly obese patients and is associated with increased risk of cardiac arrhythmias1
  • Has been found to affect as many as 77% of bariatric surgery candidates2
  • Increases the occurrence of major post-operative complications in bariatric surgery patients3 and increases hospital costs in this patient group4
  • Must be considered as part of perioperative care for bariatric surgery5
  • Air pressure treatment required may fluctuate post-operatively because bariatric patients undergo dramatic physical changes (e.g., weight loss). Automatic positive airway pressure (APAP) devices should be considered as a treatment choice during this time.6
  • Is improved by weight loss. Surgery does not necessarily eliminate sleep apnea in obese patients, necessitating long-term follow-up and monitoring.7
  • Can reappear with post-operative weight gain in bariatric patients.8
  • Development and severity may be increased by weight gain.9
