I am 60, healthy and rarely drink alcohol. My family doctor recommends bed rest, but my internist doesn't think this is necessary. Enzymes are protein substances present in body tissues. When they leak out into the bloodstream in excessive amounts, they can be measured, enabling doctors to tell which organ is inflamed or malfunctioning. Your high enzyme level suggests that an active process is affecting your liver.
Diagnosis is important because treatment depends on the cause.
You may even need an abdominal CT scan, referral to a liver specialist or perhaps a biopsy. There is an additional twist that you should be aware of. The liver enzyme called alkaline phosphatase is also produced in bone. Normal adolescents often have elevated alkaline phosphatase levels, not because of liver disease, but because the enzyme is released from healthy, growing bones. Alkaline phosphatase levels can also be related to bone disorders, such as Paget's disease.
