Hi welcome to Health care magic forum. Youare using gluconorm
pg2 since 6years, with out side effects, means the symptoms you are facing now may not be due to the drug. these may be symptoms of some other co existing disease like heart problem, hypo thyroidism,chest disease, gastritis anaemia
etc. as you have mentioned you are getting hypglycemia probably now the dose might be overdose for this age so you can modify the dose or the drug with the advise of your endocrinologist
Besides i advise you some diet recomendations as avoid taking spices, chillies, junk foods, oily foods. cut oil consumption to half . avoid un timely meals.
Take more of green leafy vegetables, pulses, sprouts, raw vegetables, milk and egg to improve blood, general health and resistance to combat such conditions.Wishing for a quick recovery and thanks for calling.
