I'm new here and a little nervous. I went to dr. in Nov. for problems with constipation. Dr. ordered blood tests to see if everything looked ok. Come to find out, on November 15th, my ASTcame back at 57 & ALT was 70. That brought some concern so Dr. wanted a hep c test. Came back Hep C reactive. Dr. ordered another blood test on Dec. 20th to check viral load and came back: Reference range: Not detected. Dr. ordered another test just yesterday to check ALT & AST and came back ALT 119 and AST 103. Now I am scared to death. I have an appt. with hepatologist Friday. I am just a mess. What could possibly make the ALT & AST levels go up so much so quick. I do not drink. I have taken a lot of tylenol sinus medication over the years for terrible sinus pressure headaches. The doctor originally thought that was the reason for elevated ALT numbers. Doc told me to stop all tylenol and for headaches try Aleve. I did that. Now I cannot help but wonder if I have something very serious wrong since the numbers went up so much in a very short time. Has anyone experience this? Please help.
