If you need to know which are the HDL cholesterol reference ranges or you require more information about the role of HDL cholesterol in the blood, you can visit normal HDL cholesterol level in the blood
HDL cholesterol, also called the “Good cholesterol” is the responsible of transport the excess of cholesterol from the bloodstream to the liver to be eliminated.
For that reason, if HDL cholesterol level in the blood is low, excess of cholesterol will not be properly eliminated from the bloodstream and there is a risk of suffering atherosclerosis, accumulation of cholesterol on the inner walls of the vessel, which can narrow an artery.
A low level of HDL cholesterol increases the probability of suffering a cardiovascular disease (stroke, heart attack, etc.) in the future.
HDL Cholesterol values are usually given in mg/dl but sometimes you can see those values in mmol/l following the International System of Units (SI). In case your values are in mmol/l you can convert them using this tool:
HDL cholesterol level is a bit low. If total cholesterol and LDL cholesterol are not over normal range it is not a matter for concern.
You should try to follow a balanced diet, increase the intake of Omega-3 products (fish or olive oil), lose weight if you are overweight and cut down on tobacco. Get a new blood test in a few months and it is probable that the LDL level returns to normal range.
If total cholesterol, LDL cholesterol or triglycerides are higher than normal range, you should visit your doctor.
Moderate HDL hypocholesterolemia requires follow-up because the risk of suffering a cardiovascular disease (stroke, heart attack, etc.) increases considerably.
It is a matter of concern id LDL cholesterol is above 150 mg/dl or there are other cardiovascular risk factors (smoking, sedentary lifestyle, high blood pressure, diabetes or obesity). In that case, if your doctor considers it appropriate, he will give you medication to combat cholesterol levels. Vitamin B3, also called niacin, may be very effective.
HDL cholesterol level is very low ant the risk of suffering a cardiovascular disease is high.
If triglyceride levels in the blood are above the normal range, the situation is worse and a visit to your doctor is mandatory. He will probably prescribe you medication. You should also follow a healthy lifestyle (balanced diet, lose weight, do regular exercise, stop smoking). If triglyceride levels are above 500 mg/dl the risk is higher.
In case triglycerides were not high, a genetic disease is a possibility. Tangier disease or Lecithin cholesterol acyltransferase deficiency should be considered and maybe to perform a genetic screening is appropriate.
To suffer a particular health situation or taking some drugs can reduce your HDL cholesterol level in the blood:
The following diseases can explain a HDL cholesterol level in the blood lower than normal:
