High Cholesterol Resource Center

High cholesterol means that you have high levels of lipids, or fats, in your blood. While your body needs cholesterol (a waxy, fatlike substance) to function, excess cholesterol can leave fatty deposits in your arteries, which can grow into plaque and increase your risk of heart disease and stroke. Also known as hyperlipidemia or hypercholesterolemia, high cholesterol doesn’t cause any symptoms for most people and is diagnosed through a blood test. Both genetics and lifestyle factors, such as diet and exercise habits, can contribute to high cholesterol. You can manage high cholesterol with lifestyle adjustments and medication.

FAQ

What are the worst foods for high cholesterol?

Meat and dairy high in saturated fat, sugary foods and drinks, and highly processed foods are the worst foods for high cholesterol. Alternatively, options like lean proteins, whole grains, and fresh produce can support healthy cholesterol levels.

Can stress cause high cholesterol?

Yes, research indicates that chronic stress can contribute to high cholesterol. Your body releases cortisol and adrenaline in response to stress, and both of these hormones increase blood sugar levels, which can then cause your body to create more cholesterol.

What will happen if your cholesterol is high?

High cholesterol levels can lead to the development of fatty deposits in your blood, which can grow into plaques that can create blockages in your arteries. Deposits that break free and form clots can cause a heart attack or stroke.

How do you bring your cholesterol down?

You can bring your cholesterol down with lifestyle changes and medication. Following a heart-healthy diet, increasing your physical activity, and quitting smoking can all help reduce cholesterol. Medications like statins, bile acid sequestrants, and cholesterol absorption inhibitors can also help.

How often should I get my cholesterol checked?

Healthy adults should get their cholesterol checked every four to six years. If you’re starting a new cholesterol medication, get your levels checked again within one to three months and monitor them regularly every three months to a year.
