Knowing your cholesterol levels is essential to managing cholesterol plaque buildup.
How does too much cholesterol affect the body?
Cholesterol is a type of fat found in foods from animal sources, such as egg yolks, meat, and cheese, and is also produced naturally by the body. As indicated by MedlinePlus, if you have too much cholesterol in your blood, it can combine with other substances to form plaque, which can build up in your arteries.
Atherosclerosis
What is atherosclerosis?
Atherosclerosis is a condition in which plaque builds up in the arteries, reducing the supply of oxygen-rich blood to vital organs, according to the NHLBI, NIH. This condition develops slowly over time as cholesterol, fat, blood cells, and other substances in the blood form plaque. To prevent this condition, it is important to maintain a healthy lifestyle with regular exercise and a balanced diet.
What are the risks of having high cholesterol levels?
Cholesterol is an essential building block for the human body, but too much cholesterol in the blood can increase the risk of cardiovascular disease. Cited on NCBI Bookshelf (WebAug 14, 2013), arteriosclerosis develops when cholesterol levels in the blood become too high and the artery walls become too thick. High cholesterol can increase the risk of heart attack and stroke.
What can cause a build-up of cholesterol on artery walls?
High cholesterol can lead to a dangerous build-up of cholesterol and other deposits on artery walls, which can restrict blood flow, according to Mayo Clinic. These plaques are a result of atherosclerosis and can be caused by lifestyle factors such as an unhealthy diet, smoking, and lack of exercise. High cholesterol can be inherited or caused by certain medical conditions.
