Understanding Cholesterol
Key Information
- Cholesterol is a type of fat that is naturally present in your blood and is essential for keeping your body's cells healthy. However, too much of it can cause problems.
- The most important thing to know is that high cholesterol usually has no symptoms. The only way to know your levels is with a simple blood test.
- Over time, 'bad' (non-HDL) cholesterol can build up in your artery walls. This can narrow them and significantly increase your risk of serious problems like heart attacks and strokes.
- If your cholesterol is found to be high, please don't panic. There are effective ways to manage it.
