Most women have never looked at two numbers on their lab report — AST and ALT — but they tell something important about how your body is handling everything else.
AST and ALT are enzymes that live inside liver cells. When the liver is under stress, those enzymes start leaking into the bloodstream. Elevated levels are a signal that the liver is working harder than it should be.
Why does that matter? Your liver processes a significant amount of what moves through your body — including hormones and medications. These numbers can also pick up early signs of fatty liver disease, which is common when there's a metabolic issue going on and almost never causes symptoms until it's well advanced. You can't feel it happening.
That's exactly why these numbers are worth paying attention to before there's a reason to.
Save this for the next time you're looking at your labs.
