Hi and welcome to HCM. yes, but it is not likely that this blockage would happen after so many years. These findings can be elevated in any liver disease including viral hepatitis, cirrhosis or infections. Most common cause is fatty liver and it is treated by certain medicines and diet. you need to regulate your blood sugar and lipids. Avoid alcohol, fatty food, fried food, certain drugs and eat more fruit and vegetables. Regulate body mass. if there is fever and pain under right rib cage,you should do some tests to rule out cholangitis. Wish you good health. Regards
