I exercised vigorously, drank a lot of water, and then went in for a blood test.  THe results show my ALT at 33 and AST at 49.  I go for a Hepatic Function Panel next month to look into this further.  Can exercise increase AST levels?  I am also a two times 10 year survivor of Hodgkins Lymphoma and received both radiation and Chemo.  My thyroid function tests were normal.  Thanks for your response

Summarized question: What causes higher level of AST with a history of Hodgkin lymphoma?
