A condition in which there are high levels of fat-like substances, called lipids, in the blood.

Examples of lipids include cholesterol and triglycerides. These substances can attach to the walls of blood vessels and restrict blood flow. This creates a risk of heart attack and stroke.

Hyperlipidemia does not cause any symptoms. A blood test to check cholesterol levels, called a lipid panel or lipid profile, is used to diagnose hyperlipidemia.

Treatments include medicines, a healthy diet and exercise.
