CHENNAI: A recent study by Deloitte states that 115 million Indians have Obstructive Sleep Apnea (OSA), which constitutes approximately nine per cent of the total population of the country. Sleep-Disordered Breathing (SDB) is an independent risk factor for the development of hypertension and other cardiovascular diseases, including strokes and ischemic heart disease. The association between sleep disorders and diabetes mellitus is observed by many doctors and they have reported the presence of obstructive sleep apnea in patients with type 1 diabetes. Fifty per cent of the patients with type 2 diabetes suffer from OSA but less than 1% are treated. Conversely, estimates suggest that up to 50% of people with OSA will have diabetes. It is important for us to focus on preventing diabetes which is snowballing with death ratio of diabetic patients higher than that of AIDS and breast cancer.
