Hi. I have recently done my LFT test and found that my cholesterol is high. After seeing this report, I am a little worried and do not know what to do. I am attaching my report. Please suggest what I can do to reduce cholesterol. I live in a mess, so food is not fully under my control, but I am trying to avoid non vegetarian food. Please advise.
