Im having elevated ldl cholesterol above 190mg/dl from past 3 yrs , with lifestyle modification and diet changes i have reduced my weight by 7kg and ldl cholesterol to 158mg/dl. Despite of the changes im having borderline high ldl  cholesterol. I have also done lipoprotein a test which is also on the higher side . Do I require to take statins for indefinite period or I can decrease cholesterol levels further by diet and exercise alone.
