Symptom: Abnormal Liver Enzymes

Abnormal liver enzymes are higher-than-average levels of proteins produced by the liver and found in the blood. Elevated or abnormal liver enzymes can be diagnosed through liver function tests, which check for the levels of these particular enzymes in the blood. Abnormal liver enzymes occur when there is a problem with healthy liver function, which causes the enzymes normally found in the liver to pass into the blood. Abnormal liver enzymes can be caused by a disease of the liver and may indicate damage to the liver. Other causes of abnormal liver enzymes include hepatitis, obesity, use of pain medications, alcohol use, celiac disease, infection or inflammation, and sometimes a heart attack.
