Our patients tell us that the quality of their interactions, our attention to detail and the efficiency of their visits mean health care like they've never experienced. The Mayo Clinic experience and patient stories Exercise on most days of the week for at least 30 minutes. Lose extra pounds and maintain a healthy weight.Limit the amount of animal fats and use good fats in moderation.Eat a low-salt diet that emphasizes fruits, vegetables and whole grains.To help prevent high cholesterol, you can: The same heart-healthy lifestyle changes that can lower your cholesterol can help prevent you from having high cholesterol in the first place. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain. If blood flow to part of your heart stops, you'll have a heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site - blocking the flow of blood or breaking free and plugging an artery downstream. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease. These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as: High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). Plaque and blood clots can reduce blood flow through an artery. If a plaque ruptures, a blood clot can form. Plaque can cause an artery to become narrowed or blocked. If there's too much cholesterol in the blood, the cholesterol and other substances may form deposits called plaque. As you age, your liver becomes less able to remove LDL cholesterol. Even young children can have unhealthy cholesterol, but it's much more common in people over 40. Drinking too much alcohol can increase your total cholesterol level. Cigarette smoking may lower your level of HDL, the "good," cholesterol. Exercise helps boost your body's HDL, the "good," cholesterol. Having a body mass index (BMI) of 30 or greater puts you at risk of high cholesterol. Trans fats are often found in packaged snacks or desserts. Saturated fats are found in fatty cuts of meat and full-fat dairy products. Eating too much saturated fat or trans fats can result in unhealthy cholesterol levels. Medical conditions that can cause unhealthy cholesterol levels include:Ĭholesterol levels can also be worsened by some types of medications you may be taking for other health problems, such as:įactors that can increase your risk of unhealthy cholesterol levels include: For example, your genetic makeup might make it more difficult for your body to remove LDL cholesterol from your blood or break it down in the liver. Factors beyond your control might play a role, too. Having a high triglyceride level also can increase your risk of heart disease.įactors you can control - such as inactivity, obesity and an unhealthy diet - contribute to harmful cholesterol and triglyceride levels. HDL, the "good" cholesterol, picks up excess cholesterol and takes it back to your liver.Ī lipid profile also typically measures triglycerides, a type of fat in the blood. LDL cholesterol builds up in the walls of your arteries, making them hard and narrow. LDL, the "bad" cholesterol, transports cholesterol particles throughout your body. There are different types of cholesterol, based on what the lipoprotein carries. This combination of proteins and cholesterol is called a lipoprotein. Cholesterol is carried through your blood, attached to proteins.
