What is HDL?

HDL or Lipoprotein with high density is commonly referred to as "good cholesterol". Unlike LDL, low density lipoproteins, which should be on low levels, should be relatively high in the body in the body. HDL helps excessive cholesterol returning to the liver to secrete the gastrointestinal system. HDL is known as good cholesterol because it helps to remove cholesterol, which can block arteries and reduce blood flow. The levels

HDL are obtained by means of a simple blood test. The blood test is ordered by a doctor either as part of a routine physical or for screening purposes. This blood test is called a lipid profile and measures HDL and LDL levels along with total cholesterol. The test provides doctors indicators to help evaluate the risk factor of the patient for heart disease. Cholesterol levels are measured in milligrams on blood deciliter.

When a lipid profile is ordered, the doctor may require a 12 -hour fast test and may also require a certain mediciney were temporarily stopped. Cholesterol testing is important, especially in patients who are already at risk of heart disease, such as smokers, diabetics or people with high blood pressure or weight. The target cholesterol levels of each person vary slightly, but in general, HDL levels should be 60 mg/dl or higher and at least 40 mg/dl to avoid endangering.

Unlike LDL levels, which sometimes focuses on diet decreasing cholesterol, HDL levels are more associated with man's lifestyle than the diet itself. Smoking, obesity and sedentary activities are directly associated with low HDL levels in the blood. Weight loss, smoking quit and exercise will increase HDL levels. However, control of overall cholesterol is a combination of increasing good and reducing the bad - a process that should include changes in diet and lifestyle. When lifestyle ACE and diet is not enough or if the patient refusese make changes, the doctor may prescribe a drug to increase HDL levels.
