Cholesterol is a waxy substance your body needs to build cells and make hormones. Problems arise when certain types build up in your blood and contribute to narrowed arteries over time.
The main types
- LDL ("bad") cholesterol: can build up in artery walls. Lower is generally better.
- HDL ("good") cholesterol: helps carry cholesterol away from the arteries.
- Triglycerides: another blood fat that, when high, may raise heart disease risk.
Why testing matters
High cholesterol usually has no symptoms. A simple blood test is the only way to know. Your doctor will interpret the results alongside your age, family history, blood pressure and other factors.
Lifestyle habits that help
- Eat more fibre, especially oats, beans and fruit.
- Choose healthy fats like olive oil, nuts and fish over saturated and trans fats.
- Move regularly.
- Maintain a healthy weight.
- Don't smoke, and limit alcohol.
Is it all about diet?
Not entirely. Genetics play a big role, and some people with healthy habits still have high levels. That's why medical advice matters.
Some people need medication in addition to lifestyle changes. Talk with your doctor about the best plan for you.
General information only, not medical advice. Always talk to a qualified health professional about your own situation.
