Hypercholesterolemia, or high cholesterol, occurs when there is too much cholesterol in the body. Your body makes all the cholesterol it needs. High cholesterol raises your risk for cardiovascular disease, heart attack, and stroke. When there is too much cholesterol circulating in the blood, it can create sticky deposits (called plaque) along the artery walls. Plaque can eventually narrow or block the flow of blood to the brain, heart, and other organs.

Causes:

some can be hereditary but usually it is due to a diet high in refined carbohydrates and saturated fat with very little exercise

Signs and symptoms:

if high cholesterol goes unchecked it can cause heart attack and stroke. It can be associated with diabetes, hypertension and hypothyroidism.

Diagnosis: lipid profile through blood tests
