I have an hepatic test and the ALT enzimes are 3 times higher than normal, that means that I had hepatitis a, b or c?

Probably not. The alt & ast are very sensitive tests. That is probably the first time you have had them taken, if not compare with the previous. I would get it checked again in 4-5 months, lose weight if obese!. Other things that can increase alt are alcohol intake above moderation , viral infections (that are not hepatitis), mononucleosis, muscle injury, obesity, burns and obesity. Don"t panic! ask your dr.
