Median age of these 21 patients was 54 years (range 23\u201375) and median estimated disease duration was 60 months (range 24\u2013300). The frequency in SA patients of impaired glucose tolerance, diabetes mellitus (DM), and hypertension was 19, 33.3, and 71.4% respectively. Goiter was found in 10 patients (47.6%) and obesity in 18 (90%). Median GH level was 14\u200a\u03bcg\/l (1.4\u2013198) and median %IGF-I (percentage above the upper limit of normal range of IGF-I) was 181% (\u221231.6 to 571.2). The prevalence of SAS was 52.4%.
