- HDL: High density lipoprotein. Lipoproteins are combinations of lipids (fats) and proteins. They are the form in which lipids are transported in the blood. The high density lipoproteins transport cholesterol from the tissues of the body to the liver so it can be gotten rid of in the bile. HDL cholesterol is therefore considered the good cholesterol. The higher the HDL cholesterol level, the lower the risk of coronary artery disease.

HDL cholesterol: How to boost your 'good' cholesterol HDL cholesterol: How to boost your 'good' cholesterol. Make your lifestyle count. HDL levels are typically lower in people who have metabolic syndrome — a cluster of conditions that include obesity, increased blood pressure and high blood sugar levels. In addition to helping you lose weight, increased physical activity can lower your triglycerides while increasing your HDL levels.

What Does a High HDL Level Mean? Total Cholesterol/HDL Ratio The ratio of total cholesterol to HDL is considered the best indicator for heart disease risk. Since HDL protects the heart and vessels, increasing the HDL level may be as important as decreasing the total cholesterol. A person with a ratio of 3.4 for men, or 3.3 for women, has half the average risk of heart disease. A person with a ratio of 24 for men, or 11 for women, has three times the average risk.

- The test for high-density lipoprotein cholesterol (HDL-C) is used along with other lipid tests to screen for unhealthy levels of lipids and to determine the risk of developing heart disease.

How to Increase Your HDL Cholesterol Levels High levels of HDL cholesterol, often called good cholesterol, are associated with a reduced risk of coronary artery disease (CAD). It appears that HDL particles scour the walls of blood vessels, cleaning out excess cholesterol that otherwise might have been used to make the plaques that cause CAD.

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.

What Does a Low HDL in the Blood Mean? A low level of high-density lipoprotein, or HDL cholesterol, in the blood is a risk factor for cardiovascular disease, heart attack and stroke. Scientific studies indicate that HDL can remove cholesterol from fatty plaques in artery walls.

- High-density lipoproteins (HDL) carry cholesterol away from the cells in your body. HDL cholesterol is sometimes called good cholesterol because it helps remove cholesterol from your artery walls. The liver then removes the cholesterol from your body.

- 1 Within two months of starting, frequent aerobic exercise can increase HDL cholesterol by about 5 percent in otherwise healthy sedentary adults. 2  Your best bet for increasing HDL cholesterol is to exercise briskly for 30 minutes five times a week.ven small changes to your daily habits can help you meet your HDL target. 1  Don't smoke. 2  If you smoke, quit. 3  Quitting smoking can increase your HDL cholesterol by up to 10 percent.

HDL cholesterol: How to boost your 'good' cholesterol For HDL cholesterol, or good cholesterol, higher levels are better. High-density lipoprotein (HDL) is known as the good cholesterol because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.

"What Does ""cholesterol HDL Ratio"" Mean?" What does it mean when your HDL is low? The cholesterol/HDL ratio is calculated by dividing a person's HDL measurement into his total cholesterol measurement, states Mayo Clinic. HDL, or high-density-lipoprotein, is known as good cholesterol.

Cholesterol Charts (What the Numbers Mean) Less than 200 mg/dL: desirable. 200-239 mg/dL: borderline high risk. HDL (high density lipoprotein) is considered the good cholesterol because it may help decrease the cholesterol buildup in the walls of arteries that causes narrowing of their openings. LDL (low density lipoprotein) is considered bad cholesterol.

- HDL Cholesterol. When it comes to HDL cholesterol -- good cholesterol - a higher number means lower risk. This is because HDL cholesterol protects against heart disease by taking the bad cholesterol out of your blood and keeping it from building up in your arteries. A statin can slightly increase your HDL, as can exercise.

HDL Cholesterol: The Good Cholesterol HDL is short for high-density lipoprotein. Each bit of HDL cholesterol is a microscopic blob that consists of a rim of lipoprotein surrounding a cholesterol center. The HDL cholesterol particle is dense compared to other types of cholesterol particles, so it's called high-density. Cholesterol isn't all bad.

- Activity Level, Weight, and Lifestyle Changes. Activity Level. Regular aerobic exercise at moderate to high levels helps to lower TG, raise HDL and maintain ideal body weight. Ideally, one should exercise 5–7 days per week for 30 minutes per day; or 60 minutes per day to achieve weight loss. Activity can be broken into segments throughout the day.

High-density lipoprotein HDL particles remove fats and cholesterol from cells, including within artery wall atheroma, and transport it back to the liver for excretion or re-utilization; thus the cholesterol carried within HDL particles (HDL-C) is sometimes called good cholesterol (despite being the same as cholesterol in LDL particles).

Cholesterol management guide HDL cholesterol: The good cholesterol. While doctors will tell you high cholesterol is bad, it is important to remember that one type of cholesterol is good. High-density lipoprotein, or HDL, is useful because it carries cholesterol away from the cells and back to the liver to be processed.

HDL vs. LDL Cholesterol Differences, Normal Ranges, and Meanings HDL (high-density lipoprotein, or “good” cholesterol) and LDL (low-density lipoprotein, or “bad” cholesterol) are two types of lipoproteins that carry cholesterol to and from the body’s cells in the blood.

HDL Medical Definition of HDL. : a lipoprotein of blood plasma that is composed of a high proportion of protein with little triglyceride and cholesterol and that is associated with decreased probability of developing atherosclerosis—called also alpha-lipoprotein, good cholesterol, high-density lipoprotein; compare ldl, vldl.

- Realize that HDL is not cholesterol. Contrary to popular belief, HDL is not a type of cholesterol; rather, it's a type of cholesterol carrier or shuttle. There's only one type of cholesterol and it's essential to the body because it's needed to make all cell membranes and some hormones.

Cholesterol Tests - know your numbers HDL-Cholesterol (HDL-C) - the amount of good cholesterol, ideally it should be over 1mmol/L* (men) and over 1.2mmol/L* (women). TC:HDL ratio This is the TC figure divided by the HDL-C figure. A ratio above 6 is considered high risk - the lower this figure is the better.

High-density lipoprotein Unlike the larger lipoprotein particles which deliver fat molecules to cells, HDL particles remove fat molecules from cells which need to export fat molecules. The fats carried include cholesterol, phospholipids, and triglycerides; amounts of each are quite variable.

LDL cholesterol LDL cholesterol. n. A lipoprotein with a relatively high concentration of lipids and low concentration of protein that incorporates cholesterol and transports it to cells. High levels are associated with an increased risk of atherosclerosis and coronary artery disease. Also called low-density lipoprotein.

HDL (Good) vs. LDL (Bad) Cholesterol Meaning, Ratios, and Ranges Triglycerides can increase the risk for these diseases if there are low levels of HDL and high levels of LDL in the blood. What Are VLDL (Very-Low-Denisty Lipoproteins)? VLDL (very- low - density lipoproteins) are compounds in the plasma of the blood composed of triglycerides, small amounts of cholesterol, phospholipids, fat-soluble vitamins, and protein.
