Excessive cholesterol in the blood gradually accumulates over years within the walls of blood vessels. This accumulation leads to the narrowing and eventual blockage of these vessels. The specific health problems and diseases that arise depend on which arteries are affected. Symptoms of high cholesterol are typically not due to sudden increases but rather the long-term buildup of cholesterol in vessel walls.
When cholesterol accumulates in the coronary arteries, which supply blood to the heart, it can cause blockages and narrowing. This can result in serious issues such as chest pain, heart attacks, and heart failure. Such conditions may necessitate interventions like coronary bypass surgery (surgical removal of the narrowing) or angioplasty (widening of narrowed coronary arteries with a balloon).
Accumulation of cholesterol in the carotid arteries, which supply blood to the brain, can lead to strokes, speech impediments, balance problems, and loss of consciousness. In the renal arteries, cholesterol buildup can contribute to high blood pressure and kidney failure.
Furthermore, cholesterol accumulation in the main artery (aorta) is also dangerous. Plaques that break off from the aorta can travel and block smaller arteries in other parts of the body, leading to a variety of severe complications. These blockages can result in conditions such as intestinal necrosis (bowel death), blindness (if eye vessels are blocked), or gangrene (if leg vessels are blocked).
By the time symptoms related to high cholesterol appear, significant damage may have already occurred, often indicating that treatment is initiated at a late stage. Therefore, preventing high cholesterol and actively lowering it if elevated is of paramount importance for long-term health.
