What causes liver functions to be elevated when you are a healthy person who does not drink ect.?

ALT/AST: Most commonly, in the person that doesnt drink, the alt/ast of the liver can be elevated from acetaminophen. Frequent use of this drug can have some liver toxicity and cause the enzyme levels to increase. In general, those enzyme increase with hepatitis. Keep in mind, hepatitis does not have to be viral. It is simply a term to describe inflammation of the liver. Wishing you'all the best.

Multiple: From fatty liver to pre diabetes, elevated liver function tests in an otherwise healthy individual is not an uncommon finding on routine labs. Please sit with your doctor and review these things.

Many causes: The most common causes for elevated liver enzymes such as AST and alt in someone asymptomatic are drugs (many medications), chronic viral hepatitis, and fatty liver. Early liver disease is often asymptomatic and symptoms only arise after many years.

Healthy elevated liv: Bunch of possibilities; could be fatty liver, hepatitis c, celiac disease, herbals/otc meds, etc etc etc. See your gastroenterologist for some baseline labs and an ultrasound to try to ferret out the answer.
