I AM 62 YEARS OLD & a medical doctor by profession. Til age of 59, my fasting/pp blood sugar used to be 70/110. Now it has risen to 105/140. To me, it appears that some deficiency has occurred in utilization of sugar by the cells of my body & their efficiency may have decreased which I am not able to notice/detect except that I feel lazy & cold. I need many more woolen items to keep myself warm & at some time I lack sufficient clothes, I get common cold, viral fever-like symptoms. Can I take some little medicine in low dose to bring it near my previous level of 70/110 mg%? Will it be useful or may be harmful?
