Hello, I had HCV and have diabetes. I was able to treat the virus while controlling my sugar. Sometimes the diabetes can be a impacted of having the HCV and/or a damaged liver however it can still be controlled. The above member had a good idea for you to do a search. It is right next to where you posted your question.
Good luck to you and your Dad
Type this in that box for more info "Diabetes Medicine while cirrhosis but
compensated". Remember that people on this forum aren't doctors. We don't
know your Dad's condition of his liver either. Read the referenced posts and
I'm sure others will give you more information.
Best To You
See the top of the forum left of "Post a question"? Click on " Back To Community". Then see the box just under the forum heading. It says
"search the community" in the box. Click on the box and type "Diabetes".
There is lots of posts you can read about diabetics and Hepatitis C.
