High blood cholesterol, also known as dyslipidemia, is a condition characterized by abnormally elevated cholesterol levels in blood, especially the LDL cholesterol fraction and total cholesterol.
It is one of the major modifiable risk factors for heart disease, stroke, and peripheral vascular disease.
The causes of high cholesterol can be genetic or acquired.
Acquired causes are much more common and may include unhealthy dietary habits such as high fat, high calorie diet, high sugar intake, smoking, and sedentary lifestyle etc.

In most patients, high blood cholesterol goes unrecognized for many years because it is largely asymptomatic.

However, some patients exhibit certain signs of high blood cholesterol.

1. Xanthelasma
2. Arcus cornea
3. Recurrent chest pain
4. Intermittent claudication
