What is Pure Hypercholesterolemia?

Pure Hypercholesterolemia which is also known by the name of Familial Hypercholesterolemia is a genetic condition in which people have a tendency to have high cholesterol or lipid levels genetically. Having high levels of cholesterol predisposes an individual towards cardiac conditions along with some other potential complications. Due to high cholesterol levels, there are excessive fatty deposits in the vessels which make it tough for the blood to flow through arteries because of which the heart is deprived of the oxygen rich blood that it normally requires for normal functioning causing a heart attack. A stroke may also occur due to low blood flow to the brain due to the fatty deposits. Therefore, it is always advised by physicians to keep the cholesterol in check, maintain a healthy diet and have a healthy lifestyle.
