LDL and HDL Cholesterol: "Bad" and "Good" Cholesterol

Jan 31, 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. Apr 12, There are two main types of cholesterol: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). (Lipoproteins are made of fat and protein, and serve as vehicles for your cholesterol to travel through the blood.) Cardiologists are often asked about low-density lipoprotein (LDL) versus high-density lipoprotein (HDL).

Known as lipid, cholesterol is a fatty substance found naturally in the body. It thhe mainly made by the bbiological but it is also present in the food you eat. Your body needs cholesterol to function properly, as it is present in the membranes of every cell in the body, including the brain, muscles, nerves, liver, skin, heart, funcfions intestines. Cholesterol is not water-soluble and cannot travel freely in your blood unless it pairs itself with proteins to form lipoprotein, which helps transport cholesterol through your bloodstream.

Although both types what are the biological functions of hdl and ldl lipoproteins help transport cholesterol, they are not the same. In reality, they both have very different functions, structures, and effects on your health.

Sometimes, a clot forms in how to get into google plus narrowed artery and cuts blood flow, which results in a stroke or heart attack.

Excessive plaque buildup in an artery supplying blood to the legs may contribute to the development of a condition called peripheral artery disease. It works as a scavenger and takes cholesterol away from your organs and heart. Then it delivers cholesterol back to your liver, where the cholesterol is broken down and eliminated from the body. It is important to have a healthy level of HDL cholesterol in your body to stave off cardiovascular disease, including heart attack and stroke.

Proteins called B are present in low-density lipoproteins. The function of these particles changes due to a what are the biological functions of hdl and ldl in the types of proteins they contain.

Cholesterol moves through your body while Author: Annette Mcdermott. Dec 09, Low-density lipoproteins (LDL) and high-density lipoproteins (HDL) are two types of lipoproteins in your body that carry cholesterol -- respectively referred to as LDL cholesterol and HDL. Nov 28, HDL is a complex lipoprotein with a number of functions. One of its most important function is known as reverse cholesterol transport. As cells die and are replaced, they release cholesterol into your blood. HDL binds the excess cholesterol and transfers it .

Lipoproteins are made of fat and protein, and serve as vehicles for your cholesterol to travel through the blood. The difference is important to understand. HDL clears from the body via the liver. HDL may therefore prevent the buildup of plaque, protect your arteries, and protect you from atherosclerotic cardiovascular disease.

The higher your HDL cholesterol numbers, the lower your risk is for heart disease, vascular disease, and stroke. Lastly, although primarily used to decrease high LDL, some statin medications may potentially increase HDL levels moderately. Any medical treatment option should be discussed with your doctor.

It carries cholesterol to your arteries, where it may collect in the vessel walls and contribute to plaque formation, known as atherosclerosis. This can lead to decreased blood flow to the heart muscle coronary artery disease , leg muscles peripheral artery disease , or abrupt closure of an artery in the heart or brain, leading to a heart attack or stroke.

For LDL, the lower the number the better. Obesity, a large waist circumference, a sedentary lifestyle, or a diet rich in red meat, full-fat dairy, saturated fat, trans fats, and processed foods can lead to high LDL cholesterol. Lifestyle and diet changes are the main ways to prevent or lower high LDL.

A trial of eating a low-fat diet, regular aerobic activity, maintaining a healthy weight, and smaller waist circumference is an appropriate first step. It is best to set a timeline to achieve your goals with your doctor. In some cases, if those lifestyle changes are not enough, your physician may suggest a cholesterol lowering medication, such as a statin.

If you are considering over-the-counter herbal or ayurvedic medications for cholesterol, please discuss those with your physician first as well. Rarely, very high LDL is genetic and passed down in families. This condition can lead to very high LDL levels, and heart attack or stroke at a young age in multiple generations. Those individuals may require special medical treatment for prevention and treatment of atherosclerotic cardiovascular disease.

Remember, knowledge is the first step. That will give you and your physician a starting point for lifestyle changes and medications if needed. In the meantime, adopt a heart-healthy lifestyle , and do it with friends and family no matter their ages.

I had no idea there are so many non-medical experts until reading the above comments! We can certainly save a lot of money by not going to a medical doctor and, instead, consult with so many experts. Thank you for your expertise! I bet if anyone follows your advice and has any problems; you can be sued and prosecuted for practicing medicine without a license.

By the way, all stains are off patent! The last one to lose patent protection was Crestor and there are 5 generic makers on the market.

So they are not the most expenses drugs on the planet! When we lower cholesterol by prescribing statins we risk masking the symptom while patients may or may not follow through with lifestyle changes. Indeed, there is a real risk that some people may incorrectly assume because they are on the statin, they are safe continuing to eat a poor diet and not exercising.

For these reasons, some docs question the value of statins altogether. Please consider the full story next time you write about cholesterol and cholesterol reducing therapies. The most profitable and prescribed class of drugs on the planet. You failed to list the horrific sides. I rather die of a heart attack at 60 than take a statin and risk dying now of rhabdomyolytis, liver damage or diabetes among others. Statins are for people with genetic issues related to cholesterol.

Why does cessation of the smoking habit lowers cholesterol? Because it causes inflammation. Its the inflammation that is the problem.

Take an anti histamine. Exercise is pretty good tho, but too much cardio is damaging. Go lift some moderate weights with a qualified trainer and look better and live longer. Stop eating junk. The information presented and guidelines offered in this article have been contested successfully in recent times, to put it lightly. Please do.

Interestingly, cholesterol is controlled by an enzyme, UBIAD1, that also controls calcium behavior and is essential to create the form of vitamin K2 that we make endogenously, Menaquinone-4 MK When CKD patients were given vitamin K2, their cholesterol levels dropped and then, when supplementation stopped, their levels renounded. Messed up K status leads to weakened bones and ossified arteries, measured as CAC.

The best predictor of a cardiovascular event is CAC. This exceeds all the lipids measures into which cardiology has so invested. Statins increase CAC. Vitamin K2 is created from all dietary forms of vitamin K K1 and all forms of K2 but this isi mssed because of upstream mistakes surrounding cholesterol understanding. Fermented full fat dairy is high in long chain K2, yet such as this diatribe would make it seem that reduced fat dairy has better health outcome.

This is incorrect; the K2 is in the fats. Organ meats are also high in long chain K2. We have lost many foods high in K2, messed with K actions via bad dietary understanding, and toxic drugs and thus made folks have poorer K status which leads to more CAC, indicative of atheroscerosis.
