what is bad cholesterol

Low-density lipoprotein (LDL) is often referred to as "bad" cholesterol. It is one of the five major groups of lipoproteins that transport fat molecules around the body in extracellular water. High levels of LDL cholesterol can lead to a buildup of cholesterol in the arteries, a condition known as atherosclerosis, which can increase the risk of heart disease and stroke. LDL cholesterol itself is not inherently bad, as cholesterol performs important functions in the body, but an excess of LDL cholesterol can cause health issues. It is important to maintain a healthy level of LDL cholesterol to reduce the risk of plaque buildup in the arteries and related complications. Regular cholesterol checks and discussions with healthcare providers about cholesterol numbers, including both LDL and HDL cholesterol, are essential for maintaining good heart health.
