Effects of LDL on human body

Low-density lipoproteins (LDL)  are sometimes called “bad” cholesterol. High levels of LDL cholesterol can build up in your arteries, causing heart disease, form fatty, waxy deposits called plaques.Healthy total cholesterol levels — the sum of your HDL and LDL — should stay below 200 mg/dL.

To break down that number, your acceptable level of LDL (“bad”) cholesterol should be less than 160 mg/dl, 130 mg/dL, or 100 mg/dl. The difference in numbers really depends on your individual risk factors for heart disease.

High LDL cholesterol over time can damage your arteries, contribute to heart disease, and increase your risk for a stroke.

When you have too much LDL cholesterol in your body it can build up in your arteries, clogging them and making them less flexible. Hardening of the arteries is called atherosclerosis. Blood doesn’t flow as well through stiff arteries, so your heart has to work harder to push blood through them. Over time, as plaque builds up in your arteries, you can develop heart disease

Plaque buildup in coronary arteries can disrupt the flow of oxygen-rich blood to your heart muscle. This may cause chest pain called angina. Angina isn’t a heart attack, but it is a temporary disruption of blood flow.

Plaque can also block the flow of blood to arteries that supply blood to your intestinal tract, legs, and feet. This is called peripheral arterial disease (PAD).

High blood cholesterol on its own has also been implicated in the loss of memory and mental function. Having high blood cholesterol may accelerate the formation of beta-amyloid plaques, the sticky protein deposits that damage the brain in people with Alzheimer's disease.

Inshort, it effects your body in a harmful way leading to number of diseases.
