Labs:liver ("alt [sgpt]") is "high" (43).otherwise healthy. 1st, what could cause that? 2nd, what might a person want to do about that?p.s. don't drink.

Fatty liver or else?: There are 2 kinds of liver enzyme abnormalities--that signal disease of the liver cells or of the bile ducts. Abnormal liver tests may reflect fatty liver, too much alcohol, toxic exposure, occupational exposures, lot's of viral infections, metabolic problems, familial liver diseases, as well as problems with gallbladder, bile ducts, and pancreas. Start with blood tests to identify possiblities.

Multiple reasons: Very mild elevations in ALT and AST frequently have no obvious cause,& upon repeating tests, have returned to normal .Liver tests that remain elevated or climb can do so because of meds (careful w acetaminophen; many meds contain it so easy to accidentally OD), nutritional supplements (some are toxic to liver), fatty liver (can be related to obesity or alcohol), viruses,& too many others to list.
