Cholesterol is a waxy compound discovered in your blood and in your cells. Your liver makes the majority of the cholesterol in your body. The rest originates from foods you consume. Cholesterol journeys in your blood bundled up in packets called lipoproteins.
Cholesterol can be found in 2 kinds:
Low-density lipoprotein (LDL) is the "bad," unhealthy type of cholesterol. LDL cholesterol can develop in your arteries and type fatty, waxy deposits called plaques.
High-density lipoprotein (HDL) is the "excellent," healthy type of cholesterol. It carries excess cholesterol out of your arteries to your liver, which eliminates it from your body.

Cholesterol itself isn't bad. Your body needs some cholesterol to make hormones, vitamin D, and digestive fluids. Cholesterol likewise assists your organs work correctly.
Yet having too much LDL cholesterol can be a problem. High LDL cholesterol in time can harm your arteries, contribute to heart problem, and increase your danger for a stroke. Getting your cholesterol inspected at routine doctor gos to and lowering your cardiovascular disease threat with diet plan, workout, way of life changes, and medication can help decrease issues associated with heart problem and enhance lifestyle.
Cardiovascular and circulatory systems
When you have too much LDL cholesterol in your body it can develop in your arteries, clogging them and making them less flexible. Solidifying of the arteries is called atherosclerosis. Blood does not flow as well through stiff arteries, so your heart has to work more difficult to press blood through them. In time, as plaque develops in your arteries, you can establish cardiovascular disease.
Plaque buildup in coronary arteries can interrupt the circulation of oxygen-rich blood to your heart muscle. This may trigger chest pain called angina. Angina isn't a cardiac arrest, but it is a short-lived disruption of blood circulation. It's a warning that you're at risk for a heart attack. A piece of plaque can eventually break off and form the artery or a clot may continue to become narrowed which can completely obstruct blood circulation to your heart, resulting in a heart attack. If this process occurs in the arteries going to the brain or within the brain it can cause a stroke.
Plaque can likewise block the circulation of blood to arteries that supply blood to your intestinal tract, legs, and feet. This is called peripheral arterial disease (PAD).
Your body's hormone-producing glands utilize cholesterol to make hormones such as cortisol, estrogen, and testosterone. Hormones can also have an impact on your body's cholesterol levels. Research has shown that as estrogen levels increase throughout a lady's menstrual cycle, HDL cholesterol levels also go up, and LDL cholesterol levels decline. This may be one reason a woman's threat for heart problem increases after menopause, when estrogen levels drop.
Decreased production of thyroid hormone (hypothyroidism) causes a boost in overall and LDL cholesterol. Excess thyroid hormone (hyperthyroidism) has the opposite effect. Androgen deprivation treatment, which lowers levels of male hormones to stop prostate cancer development, can raise LDL cholesterol levels. A shortage of growth hormone can also raise LDL cholesterol levels.
