Why is my ALT high but everything else normal?
The bottom line. A high ALT level is usually a sign of some type of liver issue. It's important to work with your doctor to find the underlying cause of your elevated ALT, even if you don't have any symptoms. Lowering your ALT will require treating the cause, but certain dietary changes can help.
Can high ALT be temporary?
Elevated liver enzymes might be discovered during routine blood testing. In most cases, liver enzyme levels are only mildly and temporarily elevated. Most of the time, elevated liver enzymes don't signal a chronic, serious liver problem.
Can a high ALT return to normal?
In some instances, a person may lower ALT levels naturally by managing their weight, increasing their activity levels, and making diet changes. However, when high ALT levels result from more serious underlying conditions, medical treatment may be necessary to reduce levels.

They change with every meal so it is important not to panic if they go from 20 to 45 after a few months. All scores below 45 indicate a perfectly healthy score.
Is ALT 150 need for concern?
Very high levels of ALT (more than 10 times the highest normal level) are usually due to acute (short-term) hepatitis (inflammation of the liver). It is often due to a virus infection. In acute hepatitis ALT levels usually stay high for about 1–2 months but they can take as long as 3–6 months to return to normal.

Can ALT levels go up and down?
In a longitudinal analysis, we observed that levels of ALT decrease with age, independent of sex, metabolic factors, alcohol use, and results from commonly used liver function tests (bilirubin and albumin). When interpreting serum levels of ALT, physicians should consider patients' age especially in elderly.

A ratio greater than 3 is strongly indicative of alcoholic hepatitis. An important corollary is that an AST greater than 500 IU/L or an ALT greater than 200 IU/L is not likely to be explained by acute alcoholic hepatitis—even in an alcoholic patient—and should suggest another etiology.

Elevated liver enzymes may be temporary if they are due to certain supplements or medication. Stopping taking them on a doctor's advice can help lower liver enzymes. But, in some cases, high liver enzymes may be due to a serious condition such as NAFLD. A doctor can recommend suitable treatments.
Can you have high liver enzymes and nothing be wrong?
There are many causes of mildly elevated ALT and AST levels. The most common causes are nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease. In NAFLD, the liver has more fatty tissue in it than normal. Regular or heavy alcohol use can also hurt the liver and increase liver enzymes.
