Hi and welcome to HCM. Thank you for your query. It can raise LFT but not so much. Its elevation is common found in many disorders must most usually 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, overweight and elevated blood sugar. If ultrasound didnt find anything and viral markers are negative then you have no reason to be concerned. YOu should treat it by changing dietary and lifestyle habits. 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 prescribed, 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.
