<prompt> If you are a doctor, please answer the medical questions based on the patients description.I just received my labs back and LFTs are AST 46, ALT99. Also my Cholesterol was 223, LDL 129 and HDL 84. I quit smoking a month ago and am taking zoloft 50mg and b vitamins. I exercise regularly, and dont drink alcohol. Why are these so high? I weigh 135 and am 54 yr female. No health problems  <response>: Hi. Thanks for posting query at Chat Doctor. Usually ALT or AST values higher than two times the upper normal limit, is considered abnormal in some countries, ALT or AST values of more than 100 are considered abnormal. Value of AST or ALT greater than 85 or above maybe investigated further. Alcohol ingestion and obesity are common causes of fatty liver disease. However, you may have tests to rule out Hepatitis B and C infection. You have high cholestroladvice :- abstinence from Alcohol - LOW fat diet should be followed, -AVOID junk food and beverages-decreased oil consumption oily food- NO red meat-green vegetables should be ingested daily-use lemon juice lemonade once in a day-recheck liver enzymes and lipid profile after 3 months if cholesterol is still high, you have to use medication to combat the high cholesterol. Do not take any medication unnecessarily. Consult treating physician if you still need b vitamins andor Zoloft. Prevention is better than cure, and you should follow strict diet to bring the enzyme values back to normal. Hope to answer your concern. Wish you good health. Regards, Chat Doctor.
