Why are high blood cholesterol levels dangerous?

Cholesterol plays a vital role in your body, but an excess can lead to atherosclerosis, a major health concern. What is atherosclerosis? It's a condition characterized by the buildup of plaque inside the arteries. These plaques are thick, hard deposits predominantly made up of cholesterol, fatty substances, cellular waste products, calcium, and fibrin. As they accumulate, they harden and narrow your arteries, which can decrease or block the flow of blood.

Why does this pose a problem?

When blood flow to the heart is impeded, it can result in chest pain or angina. If a plaque ruptures, it may form a clot and lead to a heart attack or stroke. Atherosclerosis can affect any artery in the body, and the symptoms can vary depending on which arteries are most affected. By keeping cholesterol levels within a healthy range, you can help prevent the development of atherosclerosis and its associated complications.

Coronary artery disease (CAD) is a direct outcome of atherosclerosis within the arteries that supply blood to the heart. As plaques harden and narrow these coronary arteries, the heart muscle receives less blood and oxygen. This can lead to heart muscle dysfunction and heart attacks.

Signs and Symptoms of CAD

Often, people with CAD experience symptoms like chest pain (angina), shortness of breath, and in severe cases, heart attacks. Prevention and treatment include lifestyle modifications, such as a healthy diet, regular exercise, and medications to manage high cholesterol and other risk factors. Understanding the link between cholesterol levels and CAD is crucial for prevention and highlights the importance of regular cholesterol screening.

Maintaining optimal cholesterol levels is essential for good cardiovascular health. High blood cholesterol is a silent risk factor for various severe health conditions. Alongside atherosclerosis and coronary artery disease, high cholesterol levels can lead to stroke by narrowing or blocking the arteries that supply blood to the brain.

Peripheral Arterial Disease

Another condition, peripheral arterial disease, affects the arteries in the legs and arms, leading to pain and discomfort during physical activities. Moreover, high cholesterol can contribute to the development of chronic kidney disease, by affecting the renal arteries. It's important to manage cholesterol levels through a balanced diet, regular physical activity, and medication if necessary. Staying educated about cholesterol and its impacts on health will empower individuals to make informed decisions regarding their well-being.
