High cholesterol is a higher than normal level of cholesterol in the blood. It is more common in adults but can happen in children.
There are two types of cholesterol. One is high density lipoproteins (HDL) or good cholesterol. High levels of HDL have been linked to a lower risk of heart disease. The second type is called low density lipoproteins (LDL) or bad cholesterol. High levels of LDL cholesterol can lead to blockages in the blood vessels. High levels of cholesterol can lead problems such as heart attacks
strokes in adulthood.
Blockages in the blood vessels can lead to heart attacks.
