Causes of Too-Low HDL Cholesterol Photo Credit Shaiith/iStock/Getty Images. Cholesterol is a class of lipid/fat. Too much cholesterol in the blood, particularly low-density lipoprotein or ‘bad cholesterol, contributes to plaque formation that clogs arteries, a risk factor for heart disease. On the other hand, elevated levels of high-density lipoprotein or good' cholesterol is protective against heart disease.

- The HDL then shuttles the cholesterol back to the liver for recycling so that too much doesn't build up in the bloodstream. Problems arise when there is too much LDL, and not enough HDL to carry it back, creating an imbalance that may lead to heart disease. HDL is a protein made by the body.

What Does a Low LDL/HDL Ratio Mean? LDL and HDL are best thought of as cholesterol taxis. LDL is the “bad” taxi, because it transports cholesterol and fat from the liver into the bloodstream, where it can clog arteries. HDL is the “good” taxi, because it transports cholesterol from the blood back to the liver. As such, a low LDL-to-HDL ratio is a good thing, because it can reduce your risk of cardiovascular diseases.

- The higher the level of HDL cholesterol in your blood, the LOWER your chance is of getting heart disease. Coronary heart disease is a condition in which plaque (plak) builds up inside the coronary (heart) arteries. Plaque is made up of cholesterol, fat, calcium, and other substances found in the blood.he higher the level of HDL cholesterol in your blood, the LOWER your chance is of getting heart disease. Coronary heart disease is a condition in which plaque (plak) builds up inside the coronary (heart) arteries. Plaque is made up of cholesterol, fat, calcium, and other substances found in the blood.

Familial Hypercholesterolemia Familial hypercholesterolemia is a genetic disorder caused by a defect on chromosome 19. The defect makes the body unable to remove low density lipoprotein (LDL, or bad) cholesterol from the blood. This results in high levels of LDL in the blood.igh levels of LDL cholesterol make you more likely to have narrowing of the arteries from atherosclerosis at an early age. Those with familial hypercholesterolemia are more likely to have a family history of high cholesterol and heart disease at a younger age than normal.

- Quit smoking. This will definitely increase your HDL levels while greatly reducing your risk of other diseases. Very low fat diets will lower HDL as well as LDL cholesterol. It is best to include some beneficial fats such as those found in fish, nuts, flax, avocados, and legumes (such as soy, kidney beans, chickpeas).

Cholesterol level: Can it be too low? A high blood cholesterol level increases your risk of coronary artery disease. Lower cholesterol is usually better, but in rare cases having a very low level of low-density lipoprotein (LDL, or bad) cholesterol or a very low total cholesterol level has been associated with some health problems.

- LDL (low density-lipoprotein) cholesterol is also called bad cholesterol. LDL can build up on the walls of your arteries and increase your chances of getting heart disease. If you do not have heart or blood vessel disease and are not at high risk for developing heart disease, the following guidelines apply.

Lipid Panel Test HDL, or High-density Lipoprotein, transports cholesterol around the body and elevated levels have been correlated with fewer cardiovascular diseases. Elevated LDL, or Low-density Lipoprotein, levels can result in the formation or arterial plaques and increase the risk of cardiovascular disease.

What Your Cholesterol Levels Mean Genetic factors, type 2 diabetes, smoking, being overweight and being sedentary can all lower HDL cholesterol. Women tend to have higher levels of HDL cholesterol than men do. LDL (bad) cholesterol. A low LDL cholesterol level is considered good for your heart health. A diet high in saturated and trans fat is unhealthy because it tends to raise LDL cholesterol. In the past, doctors relied on specific ranges for LDL. Today, these ranges aren’t used anymore, and doctors consider LDL levels as one factor of many in evaluating cardiovascular risk.

Finding the Ideal Cholesterol Ratio High-density lipoprotein, or HDL, is the good cholesterol. The benefit of HDL lies in the fact that it carries bad cholesterol back to the liver. In doing so, it cleanses cholesterol from the bloodstream. Low-density lipoprotein, or LDL cholesterol, is the bad cholesterol.The higher the level of LDL cholesterol, the greater your risk of a heart attack. When the level of LDL cholesterol goes up, excess cholesterol can build up and stick to the walls of your arteries. This causes damage.his may mean that your level of high-density lipoprotein (HDL), or good cholesterol, is too low. It is best to have a high level of good HDL and a low level of bad LDL. The HDL helps keep your LDL level in check.

Familial Hypobetalipoproteinemia: A Disorder of Low Cholesterol Levels Familial hypobetalipoproteinemia is a rare, inherited condition that causes mild to extremely low LDL cholesterol levels. It mostly occurs due to a mutation in the protein, apolipoprotein b (apoB). This protein is attached to LDL particles and helps transport cholesterol to cells in the body.

High Cholesterol Low-density lipoprotein (LDL) is often called “bad” cholesterol. It delivers cholesterol to the body. High-density lipoprotein (HDL) is often called “good” cholesterol.It removes cholesterol from the bloodstream.This explains why too much LDL cholesterol is bad for the body, and why a high level of HDL cholesterol is good.or example, if your total cholesterol level is high because of a high LDL level, you may be at higher risk of heart disease or stroke. But, if your total cholesterol level is high only because of a high HDL level, you're probably not at higher risk.

Which Foods Contain LDL & HDL? High LDL levels can cause heart disease, hypertension and stroke. To lower your LDL levels, avoid foods with saturated fats. Having high levels of high-density lipoprotein, or HDL cholesterol, is healthy. HDL cholesterol helps remove LDL cholesterol from your blood, reducing your risk for disease.

- If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level. Your total cholesterol level is in the Desirable range, but your level of bad LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or good cholesterol, is too low.

HDL Cholesterol â The âGoodâ Cholesterol Explained On the other hand, HDL cholesterol is usually nicknamed “the good cholesterol” because high blood levels are associated with less risk of heart disease and low levels are associated with increased risk. In other words; there is an inverse relationship between HDL cholesterol and the risk of heart disease. It is believed that HDL’s act as scavengers, picking up excess cholesterol in the blood and transporting it to the liver where it’s broken down.

Cholesterol Levels: High, Low, Good & Bad HDL is the “good” cholesterol that keeps LDL, the “bad” cholesterol, down, according to the American Heart Association. Too much LDL cholesterol can cause deposits to build up in the blood vessels, known as plaque, which decreases the amount of blood and oxygen going to the heart.

What are HDL and LDL? Diffen › Health. Not all cholesterol is bad for the body. There are two types of cholesterol-HDL (High Density Lipoprotein or good cholesterol) and LDL (Low Density Lipoprotein or bad cholesterol). While LDL causes blockage in arteries, HDL helps transport triglycerides to the liver for excretion.ecommended level of good cholesterol is 1.55 mmol/L and above. The recommended level of LDL (bad cholesterol) is 2.6 mmol/L or lower. Sources. Sources of HDL include onions and Omega-3 fatty acids like flax oil, fish, foods rich in fibre like grains, oats, bran etc.

Structural Biochemistry/Lipids/Cholesterol HDL is known as good” cholesterol because it carries LDL away from the arteries and back to the liver, where it's passed from the body. A high HDL level helps prevent heart disease, while a low HDL level increases the risk of heart attack and stroke. Triglycerides are the most common type of fat.

How to Raise HDL Cholesterol Levels HDL, or high-density lipoprotein, has long been thought to correlate to heart-heath. HDL, often called the good cholesterol, functions as a shuttle that takes cholesterol from the blood stream (where it can form a blockage and lead to heart disease, also known as atherosclerosis) and transports it to the liver.
