On My first Check- Suger Level was 452 (Overall Chekup) , on second check up It was around 251 after having food and Before food 161 on my 3rd check-up it was 160 after Having food and 131 before . After 2nd check-up, I started to take medicine of sugar as per doctor advise.
On my fourth check-up My suger level became normal perhaps because of Medicin still, Iam having medic instructed by doctor

Can anyone tell if someone faced same issue . Will Suger remain with me always?
