LDL, or low-density lipoprotein, is a type of lipoprotein that carries cholesterol through the bloodstream. It's commonly referred to as "bad" cholesterol because high levels of LDL can increase the risk of heart disease and stroke.
Understanding LDL Cholesterol
LDL is one of two primary types of lipoproteins that transport cholesterol. Lipoproteins are essentially packages of proteins and fats that allow cholesterol and other lipids to move through the blood. Here’s a breakdown:
- What it Does: LDL primarily carries cholesterol from the liver to the rest of the body.
- "Bad" Cholesterol: The term "bad" cholesterol is used because when there is too much LDL circulating in the blood, it can build up in the walls of the arteries.
- Plaque Formation: This buildup forms plaque, a hard substance that can narrow and block arteries. This process is called atherosclerosis.
- Heart Disease and Stroke: Narrowed arteries can restrict blood flow, leading to heart attacks, strokes, and other cardiovascular problems.
Key Facts about LDL:
| Feature | Description |
|---|---|
| Type | Lipoprotein |
| Function | Transports cholesterol |
| Common Name | "Bad" cholesterol |
| Health Risk | High levels increase risk of heart disease and stroke |
| Primary Concern | Contributes to plaque buildup in arteries (atherosclerosis) |
Maintaining Healthy LDL Levels
- Regular Checkups: Blood tests can measure your cholesterol levels, including LDL.
- Diet: Limit saturated and trans fats, which can raise LDL cholesterol.
- Exercise: Regular physical activity can help lower LDL.
- Medication: In some cases, doctors may prescribe medication to help lower LDL levels.
By understanding what LDL is and how it affects your body, you can take steps to maintain healthy cholesterol levels and reduce your risk of cardiovascular disease.
