hi, gian. noted history of elevated liver enzymes. are you experiencing any symptoms like abdominal pain, jaundice (yellowing of your sclera and skin), fever, nausea or vomiting? most common causes are fatty liver, chronic alcoholism, infective and obstructive (gallstones or tumor lesions) pathologies. it is best if you consult with a doctor, preferably a gastroenterologist or a general surgeon, for physical examination and clinical evaluation. diagnostics (such as ultrasound, bilirubins, blood count, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. am also from the philippines and my clinic is open for consultation anytime. hope this helps. good day!! ~dr.kaye
