The effect of weight loss on sleep-disordered breathing and oxygen desaturation in morbidly obese men. 1982

E M Harman, and J W Wynne, and A J Block

Four morbidly obese men who had been found to have significant sleep-disordered breathing and oxygen desaturation were restudied after an average weight loss of 108 kg (range 53-155 kg). In all subjects, weight loss was accompanied by a significant reduction in the number of episodes per hour of sleep-disordered breathing events. In three of the four subjects, there was improvment in the severity of desaturation accompanying abnormal breathing. The two subjects with daytime somnolence and hypercapnia prior to weight loss showed the most dramatic improvement in desaturation. This suggests that obesity is a cause, rather than an effect, of the sleep apnea syndrome.

D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
