Understanding High Cholesterol
Cholesterol is a waxy substance your body needs to build cells and make certain hormones. Your body produces cholesterol naturally, and it also comes from some foods. However, having too much cholesterol in your blood can contribute to plaque buildup in your arteries and increase your risk of heart disease and stroke.
High cholesterol often has no noticeable symptoms, which makes regular screening important, even if you feel completely healthy.
What Causes High Cholesterol?
Several factors can affect your cholesterol levels. Some can be changed, while others are outside your control.
Diet
Foods high in saturated and trans fats can raise unhealthy cholesterol levels.
Weight
Being overweight can contribute to higher LDL and lower HDL cholesterol.
Physical Activity
Regular exercise can help improve cholesterol levels and support heart health.
Family History
Some people inherit conditions that cause very high cholesterol, such as familial hypercholesterolemia.
Age & Hormonal Changes
Cholesterol levels can change as you get older and may be affected by hormonal changes.
Certain medical conditions and medications can also affect cholesterol levels.
What Do Your Cholesterol Numbers Mean?
A cholesterol test, often called a lipid panel, measures several types of fats and cholesterol in your blood.
LDL Cholesterol
Often called "bad" cholesterol. Higher levels can contribute to plaque buildup in the arteries.
HDL Cholesterol
Often called "good" cholesterol because it helps carry cholesterol back toward the liver.
Triglycerides
A type of fat in the blood that can also contribute to cardiovascular risk when levels are elevated.
Your provider considers these numbers along with your overall health and other risk factors when determining your treatment plan.
How Can You Manage High Cholesterol?
Lifestyle changes are an important part of cholesterol management. Depending on your individual risk, your provider may also recommend medication.
Choose Heart-Healthy Foods
Include more vegetables, fruits, whole grains, beans, nuts, and lean proteins while limiting foods high in saturated and trans fats.
Stay Active
Regular moderate-intensity activity can support healthier cholesterol levels and overall cardiovascular health.
Maintain a Healthy Weight
If you are overweight, working toward a healthy weight may help improve your cholesterol profile.
Avoid Tobacco
Quitting smoking can improve HDL cholesterol and provide important benefits for cardiovascular health.
Take Medication as Prescribed
Some people need cholesterol-lowering medication in addition to lifestyle changes. Your provider can help determine what's appropriate for you.
Why Managing Cholesterol Matters
High cholesterol usually doesn't make you feel sick, but over time it can contribute to fatty deposits inside your arteries. These deposits can restrict blood flow and increase the risk of cardiovascular problems.
Managing cholesterol can help reduce your risk of:
Heart Disease
High cholesterol can contribute to plaque buildup in the arteries.
Heart Attack
Blocked or narrowed arteries can reduce blood flow to the heart.
Stroke
Plaque buildup can affect blood flow to the brain.
Peripheral Artery Disease
Narrowed arteries can also affect blood flow to the legs and other parts of the body.
When Should You Get Your Cholesterol Checked?
Because high cholesterol often doesn't cause symptoms, testing is the best way to know your levels.
Talk with your healthcare provider about cholesterol screening, particularly if you have a family history of high cholesterol or heart disease, high blood pressure, diabetes, excess weight, or other cardiovascular risk factors.
Your provider can review your results and help determine whether lifestyle changes, monitoring, or medication may be appropriate.
