People with hep C are at an elevated risk for type II diabetes. I don't think it is anything to be scared about. You might want to talk to a nutritionist to help guide you in making healthy choices. The best thing to do is avoid a lot of carbohydrates as they are sugars and will elevate your glucose. Have your A1C test as recommended by your physician. You should be just finhel. I am! :-)
Have you heard about the relatively new treatment ta for hep c?
You should ask your doctor about getting treated if you still have hep c. The new meds have about a 98% cure rate for hep c. Treatment could be as simple as 1 pill a day for 8 or 12 weeks and your hep c can be cured. Most people who have treated with the new medicines have had little in the way of side effects.
I treated 3 times in the past with interferon based treatments and have had liver cirrhosis for over 9 years. I was cured of hep c by the new medicines 2.5 years ago.
