Hi,
The more common causes of increases in AST and ALT can be due to:
(1) Non alcoholic
fatty liver disease - this is one of the most common causes as present. It is due to build up of fat in the liver which can then go on to cause inflammation and damage to the liver if it is allowed to progress. Treated with diet changes, activity and medications
(2) Alcohol - persistent use of a lot of alcohol causes damage
(3) Side effect of medications eg statins for
cholesterol. This does not happen to all persons who use the statins, only some
(4) Infection -
hepatitis is another cause of abnormal liver enzymes
(5) Hemochromatosis- iron is deposited in the liver. Your doctor may suggest an
ultrasound or CT of the abdomen to take a look at the liver.
Additional bloods, if not already done, may also be requested to determine the cause eg
complete blood count, cholesterol levels, iron and the hepatitis viruses
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Iven Romic Rommstein, General Surgeon
