hi and welcome. well i dont know your age . i also have no info whether this result is after you have been treated for high cholesterols . you have any additional risks for heart problems, eg smoking
, alcohol etc.....and indeed strong family history of raised cholesterol levels. if you have nothing of above but have family history then its also an independent risk .
first of all diet is good, thats encouraging...you must exercise that will help in reducing weight and also cholesterols . if this fails then using high fibers diet along with medicine( eg statins ) can be prescribed by your doctors. there is nothing to worry now, yes but accessing your health status is mandatory . must see a cardiologist of you have symptoms eg shortness of breath
on exertion and /or chest pain
or heaviness. regards
