Dear sir Usually constantly high blood sugars indicate acute loss of beta cells reserves in the pancreas which is responsible for secretion of insulin.. Secondly even after taking adequate medicines for the blood sugars and if you are unable to control it, then it is the time to start basal insulin at the night time. Yoga is some times not recognised as physical activity, it will improve exercise tolerance and mental stability but it is never an alternative for physical exercises. Stop gutkha once for all, if you are not able to do it volunterely then take the help of psychiatrist and do it Thanks
