Cholesterol is a waxy substance found in your blood, and your body needs it to build healthy cells. However, having too much cholesterol, particularly LDL (low-density lipoprotein), can cause fatty deposits to form in your blood vessels. Over time, these deposits can make it difficult for blood to flow through your arteries, leading to conditions such as heart disease and stroke.
Managing cholesterol involves adopting a heart-healthy diet, regular exercise, and in some cases, medications such as statins. Regular cholesterol checks are important for assessing your risk and making necessary lifestyle adjustments.
The main types are LDL (low-density lipoprotein), also known as "bad" cholesterol, and HDL (high-density lipoprotein), or "good" cholesterol. Triglycerides are another type of fat in the blood that contributes to heart disease.
Lowering cholesterol involves eating a heart-healthy diet, exercising regularly, avoiding smoking, and in some cases, taking cholesterol-lowering medications like statins.
Foods high in cholesterol include fatty meats, full-fat dairy products, fried foods, and processed snacks. Saturated fats and trans fats can also raise cholesterol levels.
High cholesterol can lead to plaque buildup in the arteries, increasing the risk of coronary artery disease, heart attack, and stroke.
Adults should have their cholesterol levels checked every 4-6 years, but more frequent testing may be needed if you have risk factors for heart disease.
