Many diseases and conditions can contribute to elevated liver enzymes. Your doctor determines the cause by reviewing your medications, your signs and symptoms and, in some cases, other tests and procedures.
More common causes of elevated liver enzymes include:
Over-the-counter pain medications, particularly acetaminophen (Tylenol, others)
Certain prescription medications, including statin drugs used to control cholesterol
Drinking alcohol
Heart failure
Hepatitis A
Hepatitis B
Hepatitis C
Nonalcoholic fatty liver disease

Other possible causes of elevated liver enzymes include:
Alcoholic hepatitis (severe liver inflammation caused by excessive alcohol consumption)
Autoimmune hepatitis (liver inflammation caused by an autoimmune disorder)
Celiac disease (small intestine damage caused by gluten)
Cytomegalovirus (CMV) infection
Epstein-Barr virus
Hemochromatosis (too much iron stored in your body)

Thyroid conditions
Toxic hepatitis (liver inflammation caused by drugs or toxins)

You shouldn’t worry about your levels. Worry is non productive. What you should do is ask your doctor about a possible cause and if needed treat any condition you may have.
Worry is a waste of time and energy and solves nothing.
