Hello First of all I want to tell you that no doubt you are at risk of high cholesterol level but now a days only life style change can alter whole situation so need not to worry about hereditary factor. Now main question. You should be worried but not too much. Your cholesterol is not that high to be very worried . You may easily get back to normal range. I see similar cases amongst young peoples who visit my clinic. In the first meeting , I advise my patients to go on life style modifications for 3 months . i retest them again after 3 months & if they continue to high range I advise them medicine . 1 High fiber diet , green leafy vegetables , fresh fruits ( not canned ) . 2 Cut down the processed food , white bread doughnuts , white sugar , pizza, should be completely avoided. 3 A 40 -50 minute physical activities everyday like morning walk or evening walk or a visit to a gym or swimming pool . Don t take tension , remain away from anxiety . If still high cholesterol I advise my patient to take a combination tablet simvastatin+ezetimibe one or two in day . Periodically check after every 15 days . Hope this will be helpful for you.
