Effect of laparoscopic sleeve gastrectomy on obstructive sleep apnea and sleepiness
The risk of OSA and the ESS score significantly decreased six months after LSG in obese patients, especially those under 45-years-old, and this surgery is recommended for fast and effective weight loss and comorbidity reduction at lower ages.
Abstract
: Background: Obstructive Sleep Apnea (OSA) and daytime sleepiness are common in obesity. Bariatric surgeries are increasingly performed for obesity treatment. The current study aimed to investigate the effect of Laparoscopic Sleeve Gastrectomy (LSG) on the risk of apnea and daytime sleepiness in morbidly obese patients. Methods: This prospective observational study was performed on 59 obese patients scheduled for LSG. Information such as age, gender, BMI, blood pressure, and neck circumference was recorded. The STOP-Bang questionnaire and Epworth Sleepiness Scale (ESS) were filled out to assess the risk of OSA and daytime sleepiness before and six months after surgery. Results: There was a statistically significant improvement in weight loss, neck circumference, blood pressure, and BMI after surgery (p less than 0.05). The OSA risk declined significantly from 3.94±1.76 to 1.07±1.06 (p less than 0.05), although improvements decreased with increasing age. Also, the ESS scores reduced significantly from 9.94±5.54 to 3.47±2.43 after surgery (p less than 0.05). Conclusion: The risk of OSA and the ESS score significantly decreased six months after LSG in obese patients, especially those under 45-years-old. Therefore, this surgery is recommended for fast and effective weight loss and comorbidity reduction at lower ages.
