I'm a 23 year old female, I'm obese though I have lost 60 lbs in the last year, and I have been having some symptoms that worry me. I have previously been diagnosed with PCOS. The doctor put me on Metformin and Yasmin, though I stopped taking the Metformin because it made me feel ill. That was over four years ago. At the time, my fasting blood sugar was 101, but I had eaten some ice cream at the beginning of the eight hour period. I had my fasting blood sugar tested again two weeks ago. I fasted for about 16 hours and my blood sugar was 87. This didn't concern my doctor, but it does concern me. I also have high cholesterol (total 286) and my liver test (ALT) came back at 86 U/L. In addition to this, I have been getting heart palipations, which I am being monitored for, and a cold feeling in my hands and chest. I've also been having trouble sleeping, though I think this is due to anxiety over my health. Could any of this be a sign of diabetes? Should I ask my doctor to do a more extensive test for diabetes?
