These definitely sound like concerns to take to your doctor! Recently, I had a test done that showed my A1c levels at 8.5%, normal is around 6%. This is a blood test that tests the glucose levels of your blood for a 3 month average and is an indicator of pre diabetes. I also had high cholesterol. Total was at 239 which is considered borderline high. I started a plan in March that has helped me lose weight, lower my cholesterol and bring my blood sugar down to normal. All without medication. I hope your visit goes well tomorrow and that your test results turn out better than mine were.
The good news is that there is a solution out there that doesn't require medication. If you want to know about it, please check out this website. Please ALWAYS get the advice of your doctor.
