Hi, my father aged 70 is having
sugar from past 30 years, from past few weeks his sugar levels are getting low very often, sometimes it is as low as 27 due to which he is becoming unconcious, unable to response etc., and this is happening in early mornings or midnights, but as soon as he eats he is getting normal. Can you please suggest me what has to be done for this? And is this normal or signs of any abnormality?
