The American Heart Association states that lipidemia, generally referred to as hyperlipidemia, is an elevated concentration of lipids in the blood. Elevated lipids, or fat, in the blood produce high cholesterol and high triglycerides that contribute to heart disease.
The human body makes and uses a certain amount of cholesterol, but genetics and diet can cause cholesterol levels to rise. According to the American Heart Association, there are two types of cholesterol. HDL cholesterol is good for the body and decreases the risk of heart disease and stroke by cleansing arteries of plaque. LDL cholesterol leads to artery blockage when a person's levels are high.
WebMD says a person’s overall health and genetic risks guide treatment for lipidemia. Healthy diet choices and increased exercise are important to lowering high cholesterol. Depending on a person’s level of risk, doctors may prescribe medication in conjunction with healthy eating and regular exercise.
Everyday Health explains that genetic abnormalities cause some people to produce excess cholesterol or prevent the body from absorbing LDL cholesterol. Hereditary conditions can cause high cholesterol and high triglycerides in people of all ages. For this reason, it is important to consult a healthcare physician about the risk of heart disease.
