Abnormal levels of liver enzymes is suggestive of liver disease, to determine which kind, further testing and examination is usually needed.
Also, high ALP might mean that you have a gallbladder problem and not a liver problem at all.
Did you have an Ultrasound scan of your abdomen to check you liver and other organs?
Were you tested for hepatitis viruses?
Was your bilirubin normal?
I would stop drinking, because any quantity of alcohol will worsen a sick liver and have it thoroughly checked.
You would be better off if you go see a Hepatologist or a Gastroenterologist.
Good luck!
you may have pancreatitis and you should also get a tsh on you to rule out hypo/hyper-thyroidism if you have trouble loosing weight... but if you are older it also may just be diet or age.
