What would cause only alt and ast to rise but normal bilirubin, albumin, ggt, ldh etc.... all other enzymes are normal. started 1 month ago. ?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, elevated ALT and AST indicate damage to liver cells. If you are overweight, lose weight. If you drink alcohol, stop entirely.

Suspect hepatitis: Liver injury(Hapatitis) of any cause(infections or chemical damage) will often affect the ALT and AST first and not have effects on Bilirubin if the damage is mild to moderate. Excessive Alcohol use is a common cause, so is Hepatitis A, Hepatitis-B and Hapatitis-C. You should go see your doctor who can do the appropriate tests to make the proper diagnosis and advice further treatment for you.
