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 elevated liver enzymes in developed countries. However, Herb and C should be ruled out. Advice for fatty liver:- 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-reduce weight if overweightobese-recheck liver enzymes after 6 to 8 weeks andor ultrasound. Any further questions are welcomed. Hope to answer your concern. Wish you good health. Regards, Chat Doctor.
