i was dx in april of this year with type 2 with a fasting bg of 320. since then i have lost 30 lbs. and a fasting bg of 140-150 and 2hr after a meal of 160-170. so after 6 months my Dr. wants me to start metformin. i wanted to try to avoid meds and the possible side affects. i think i can further improve my numbers with more dieting and exersize. are these numbers a health threat or is my Dr. just being cautious.
