News Desk, News Nation 360 : People do not focus on something which is as vital as sleep, which is why observing World Sleep Day is just as significant and important as any other. CK Birla Hospitals – CMRI, hosted a session to address issues related to sleep disorders. The session was presided by Dr Raja Dhar, Director & HOD, Department of Pulmonology, CMRI & Dr Arjun Dasgupta, Department of ENT- Otolaryngology, CMRI. Taking about sleep disorders, Dr Raja Dhar explained that if one looks at the commonest or chronic diseases that afflict mankind especially in India is Diabetes. India is supposed to be the diabetic capital of the world. If one looks at the number of diabetics, it is about 1.8% of the Indian population which is a far lower number. If one looks at the people who suffer from a sleep disorder, people who have sleep-related breathing issues, and the number is just double. It is about 8% of the Indian population which includes people from all age group. If one speaks to any patient who comes in through the door, irrespective of which speciality they go to, one will find sleep-related problems, being one of the most important complaints they have. They know that it is obese people who mainly get sleep apnea. However, they now know 25% of people with OSA have normal BMI. So, it is not the people, who are obese, it is the entire population they are targeting. Diseases like stroke, heart attack are the greatest killers of the world and are often driven by untreated sleep apnea and hence this should be addressed in the long run. Some groups are more likely to develop OSA : Men are more likely to have obstructive sleep apnea than women before age 50, After age 50, the risk is the same in men and women, Among obese patients, 70% have obstructive sleep apnea. Obstructive sleep apnea worsens in severity and prevalence with increasing obesity, Among patients with heart disease 30%-50% have obstructive sleep apnea, and among patients with strokes, 60% have obstructive sleep apnea. Obstructive sleep apnea (OSA) may be a risk factor for the development of other medical conditions. High blood pressure (hypertension), heart failure, heart rhythm disturbances, atherosclerotic heart disease, pulmonary hypertension, insulin resistance, and even death are some of the known complications of untreated obstructive sleep apnoea.
