Hi and welcome to HCM.
These are moderately elevated liver enzymes
Its elevation is common found in many disorders must most usualy is alcoholic, viral, autoimmune or toxic liver damage
. The most common liver disorders is fatty liver
which can be found in healthy people, but usually is resulting from elevated blood lipids
and elevated blood sugar. If ultrasounds didnt find anything and viral markers are negative then you have no reason to be concerned. YOu should treat it by changing dieatary and lifestyle habbits. Do exercise, avoid alcohol,smoking
, fats,fast food and carbonated drinks. Eat more fruit and vegetables, boiled meat and follow some of hepatoprotective diets. Findings usually improves on such measures. If not, then some medicines can be presribed, but I suggest to go step by step. If you dont have any symptoms then this is just slight and reversible liver damage.
Wish you good health.
