Your cholesterol results are numbers that show the levels of different types of fats in your blood. Cholesterol is a waxy substance your body needs to build cells, but too much of certain kinds can increase your risk of heart disease and stroke. The main numbers are total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol, and triglycerides. Your doctor uses these results to assess your heart health.
Key facts
Yes, high cholesterol is very common. Many adults have higher than recommended levels, often without knowing it. It can affect people of all ages, though risk increases with age.
Anyone can have high cholesterol, but it is more common in people who eat a diet high in saturated fats, are overweight, do not get enough physical activity, or have a family history of high cholesterol. It can also be linked to other conditions like diabetes or an underactive thyroid.
Cholesterol levels are measured with a simple blood test called a lipid panel. You may be asked to fast (not eat or drink anything except water) for 9 to 12 hours before the test.
A healthcare provider will take a small sample of blood from a vein in your arm. The test is quick and usually not painful, though you may feel a brief sting. Results are typically available within a few days. Your doctor will explain what the numbers mean for you and whether any changes or treatments are needed.
If your cholesterol levels are high, treatment focuses on lowering your LDL (bad) cholesterol and raising your HDL (good) cholesterol. This is usually done through lifestyle changes first, and sometimes medications are added if needed. Your doctor will create a plan tailored to your overall risk of heart disease.
Managing your cholesterol levels is a long-term commitment. You will need to have regular blood tests to see how well your treatment is working. Stick with your healthy habits and take any prescribed medications. Keep track of your numbers and discuss them with your doctor during visits.
You can lower your risk of developing high cholesterol by maintaining a healthy lifestyle: eating a balanced diet, staying active, keeping a healthy weight, not smoking, and limiting alcohol. While some factors like age and family history cannot be changed, these lifestyle choices have a powerful effect.
Regular cholesterol checks are recommended for adults starting at age 20, or earlier if you have risk factors such as a family history of high cholesterol or heart disease. Talk to your doctor about how often you should be screened.
The good news is that high cholesterol is very manageable. With early detection, healthy lifestyle changes, and if needed, medications, most people can significantly lower their cholesterol and reduce their risk of heart disease and stroke. Many people live long, healthy lives with well-managed cholesterol levels.

If lifestyle changes are not enough to lower your cholesterol to a healthy level, your doctor may recommend a medication. The most common type is a statin, which helps reduce LDL cholesterol. There are also other types of medicines that can lower cholesterol or help your body absorb less cholesterol. Your doctor will discuss the benefits and possible side effects with you. Always take medications exactly as prescribed and never change your dose without talking to your doctor.
Surgery is not usually needed to treat high cholesterol directly. However, if cholesterol has caused severe narrowing of your arteries (for example, in the heart or neck), a procedure such as angioplasty or bypass surgery may be considered. Your doctor will only recommend this if you have significant blockages causing symptoms.
A balanced diet and regular exercise are the cornerstones of managing cholesterol. Focus on a diet rich in fruits, vegetables, whole grains, and healthy fats. Limit red meat, full-fat dairy, and fried foods. Exercise helps raise your HDL (good) cholesterol and can also help you maintain a healthy weight. Even moderate activity, like a 30-minute walk most days, makes a difference.
Living with a condition that requires ongoing management can sometimes feel overwhelming. It is normal to feel anxious about your heart health or frustrated with making changes. If you feel down or worried, talk to your doctor or a counsellor. You are not alone – many people successfully manage their cholesterol and live healthy lives.
