Why is LDL called “bad” cholesterol?

Guida verificata passo dopo passo

Understand that LDL stands for Low-Density Lipoprotein, which is a type of lipoprotein responsible for transporting cholesterol in the bloodstream.

Recognize that LDL is often referred to as 'bad' cholesterol because it can deposit cholesterol on the walls of arteries, leading to the formation of plaques.

Learn that the buildup of plaques in the arteries, a condition called atherosclerosis, can narrow or block blood flow, increasing the risk of heart disease and stroke.

Contrast LDL with HDL (High-Density Lipoprotein), which is considered 'good' cholesterol because it helps remove cholesterol from the bloodstream and transport it to the liver for excretion.

Conclude that maintaining a healthy balance between LDL and HDL levels is important for cardiovascular health, and lifestyle choices such as diet and exercise can influence these levels.

Atherosclerosis is a condition characterized by the hardening and narrowing of arteries due to plaque buildup, which can be exacerbated by high levels of LDL cholesterol. This process can restrict blood flow and lead to serious cardiovascular issues, making the management of LDL levels crucial for heart health.
