Question 1

Is a slightly high ALT something to worry about?

Accepted Answer

A slightly high ALT is common and often temporary, but it is worth following up. Many cases come from fatty liver, alcohol or a medicine, and some need treatment. Your clinician will usually repeat the test and look for the cause.

Question 2

Can exercise raise ALT?

Accepted Answer

Yes. Heavy or unaccustomed exercise, especially weight training, can raise ALT and AST for several days because muscle releases them too. Avoid strenuous workouts for 24 to 48 hours before a liver test.

Question 3

Does alcohol raise ALT?

Accepted Answer

Regular or heavy drinking can raise liver enzymes, and alcohol often raises AST more than ALT. Even moderate drinking can add to the effect of fatty liver.

Question 4

How long does it take ALT to return to normal?

Accepted Answer

After a short-term cause such as a medicine or an infection, ALT often settles within weeks. With fatty liver, improvement usually follows weight loss and lifestyle changes over a few months.
