HDL cholesterol, or high-density lipoprotein cholesterol, is considered to be good cholesterol since it tends to remove plaque and excess LDL, or low-density lipoprotein cholesterol, from the arteries. These compounds are carried to the liver where they can be metabolized and excreted as waste. HDL levels above 60 mg/dL can help lower your risk of heart disease and stroke.
Definition of Cholesterol
Cholesterol is a waxy substance that is found in the majority of your cells. In order to be transported in the blood, it must bind to lipoproteins. Lipoproteins are a combination of lipids, also know as fats, and proteins. High-density lipoproteins, HDL, are believed to carry good cholesterol since these molecules can help remove plaque from your arteries. Low-density lipoproteins, LDL, are considered bad cholesterol since LDL can increase the build-up of plaque.
Understanding HDL
The higher your level of HDL, the lower your risk of heart disease and stroke. Approximately one-third of your cholesterol is carried by HDL. These particles are also responsible for picking up excess cholesterol in your system and returning it to the liver where it can be metabolized and excreted. Therefore, high levels of HDL can lower your levels of LDL. Low levels of HDL are considered to be less than 40 mg/dL and can increase your risk for heart disease and stroke.
Understanding LDL
When too much LDL circulates in your blood, it can slowly build up on the walls of your arteries and form plaque. Over time, as plaque accumulates, artery walls can thicken and harden, leading to the development of atherosclerosis. If a clot forms and blocks a narrow artery, a heart attack or stroke can result.
How to Increase Your Levels of HDL
Regular aerobic exercise may be the most effective way of raising your levels of HDL. Engaging in exercises that raise your heart rate for 30 minutes per day can be very beneficial. Obesity is a major factor contributing to the increase of LDL and the lowering of HDL. Losing weight is a vital component of having healthy cholesterol levels. If you are a smoker, attempt to quit; smoking is another major factor contributing to low HDL levels. One or two alcoholic drinks per day can also contribute to higher levels of HDL. Increasing your intake of fiber and monosaturated fats can help increase your HDL cholesterol while keeping LDL levels low.
Drugs that Increase HDL levels
There are several different types of drug therapy for cholesterol problems. Drugs that lower LDL cholesterol have been shown to be more successful than drugs that raise HDL cholesterol. Niacin, one of the B vitamins, has been shown to successfully increase levels of HDL. Niacin does have several side effects including redness, hot flashes and itching. Several drugs can be taken at once, and your doctor can help you decide which medications will successfully lower your LDL levels and increase your levels of HDL.
