Description: LDL and HDL Cholesterol: "Bad" and "Good" Cholesterol Your cholesterol levels are an important measure of heart health. For HDL cholesterol, or "good" cholesterol, higher levels are better. Cholesterol travels through the blood on proteins called “lipoproteins.” Two types of lipoproteins carry cholesterol throughout the body: LDL (low-density lipoprotein), sometimes called “bad” cholesterol, makes up most of your body’s cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke. HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke. When your body has too much LDL cholesterol, the LDL cholesterol can build up on the walls of your blood vessels. This buildup is called “plaque.” As your blood vessels build up plaque over time, the insides of the vessels narrow. This narrowing blocks blood flow to and from your heart and other organs. When blood flow to the heart is blocked, it can cause angina (chest pain) or a heart attack. Lowering Your Risk If you have high LDL cholesterol levels, your health care team may recommend cholesterol-lowering medicine and lifestyle changes to lower your risk for heart disease and stroke. If you have low HDL cholesterol levels, talk to your doctor about lifestyle changes that may help raise your levels. Medications can boost or lower HDL cholesterol HDL levels are sometimes improved by drugs used to lower LDL and triglyceride levels — such as prescription niacin; fibrates such as gemfibrozil (Lopid); and certain statins, particularly simvastatin (Zocor) and rosuvastatin (Crestor). But clinical trials for several drugs specifically designed to increase HDL levels were halted early because they didn't reduce the risk of heart attacks. Drugs containing testosterone and other anabolic steroids can lower your HDL cholesterol levels. Avoiding these drugs may help increase your HDL numbers. #hdlcholesterol #ldlcholesterol #ldl #hdl #goodcholesterol #badcholesterol #cholesterol #highcholesterol #heartattack #atherosclerosis #goodandbadcholesterol #cholesterolloweringdrugs #howtodecreasecholesterol #lowcholesteroldiet #highldl #lowhdl
