Are you going to do a blood cholesterol test? Find out what total cholesterol, LDL and HDL are, what their normal values are and why it is done.
In the XXI century it is very normal to see how more and more people have a high blood cholesterol level. In fact, there are many children who already suffer from this condition at a very young age due to the rise of sedentary lifestyle and massive intake of sweets and fats from fast food. It is estimated that there are more than 120 million cases related to childhood obesity in the world, a trend that, if not changed, will continue to increase exponentially.
The worst of it is that high cholesterol can have fatal health consequences. This is because this substance accumulates in all the arteries and veins of the body, causing oxygen and red blood cells to not reach any of the organs correctly.
And of course, this situation can later translate into heart muscles not working properly, causing hypertension and even a clear case of myocardial infarction. It is also very common for high cholesterol to increase the chances of diabetes because glucose levels have skyrocketed due to the increased consumption of triglycerides.
What is the test for total cholesterol, HDL cholesterol and LDL cholesterol?
If you have already had a cholesterol test at some point, you have probably already noticed that three parameters are included with the results of the blood test: total cholesterol, LDL cholesterol and HDL cholesterol. But what do they consist of?
- Total cholesterol: It basically consists of the sum of the following two types of cholesterol.
- LDL cholesterol: Also known as low-density lipoprotein, or popularly known as bad cholesterol, it is the cholesterol capable of clogging the arteries, being associated with heart disease and strokes.
- HDL Cholesterol: Known as high-density lipoprotein, or good cholesterol, it is recommended that its level be elevated as it helps reduce the effects of LDL cholesterol.
How is a cholesterol test performed?
In short, if what we want is to know if we suffer from high cholesterol, we will have no choice but to be very attentive to a series of symptoms that can make an appearance at any time and among which the following stand out:
- Those people who suffer from dry mouth or bad breath may denote that we are facing a clear case of high cholesterol.
- Chest and joint pain. The blockage of arteries and veins in the body caused by high levels of cholesterol can cause discomfort and pain in the chest area and some extremities such as the arm.
- Dizziness and vertigo it is also possible that due to high cholesterol, dizziness of all kinds may occur that can later translate into fainting and fainting. Given this, it is best to go to the hospital as soon as possible.
Before the appearance of any of the symptoms mentioned above, we will have to visit our trusted doctor to take a blood sample from the inside of the elbow. As with any test, it is best to go on an empty stomach without having eaten any food for the past 10-12 hours.
Normal cholesterol values
Once they have done it to us, we will wait a couple of days to know the results. After this, it will only be necessary to take into account the following premises to know first-hand if the levels of bad cholesterol (LDL) are too high.
- Any value greater than 190ml/ld. may indicate that we suffer from high cholesterol.
- If the levels are between 79/189mgandld., the person will be considered to have high cholesterol if they have diabetes or heart disease such as hypertension.
Likewise, we can know what the normal cholesterol values are by dividing it by the different types (total, LDL and HDL):
- Normal total cholesterol values: Values of 180 to 200 mg/ld. are ideal. If our cholesterol level is within these parameters, it is usual not to study LDL or HDL cholesterol.
- Normal values for LDL cholesterol: Values between 70 and 130 mg/ld. are considered normal, so that the lowest values are medically considered the best.
- Normal HDL cholesterol values: It is recommended that your values be above 50 mg/LD.
In short, it seems very important to carry out a cholesterol test every five years in order to know first-hand if we suffer from this condition that is increasingly present in our society. Although the terms should be shortened at older ages or if you suffer from diabetes or obesity.
However, if there are high values in a first blood test, the most common thing is that our doctor advises us to repeat the analysis in a few months, usually two months later, following a normal lifestyle and maintaining our eating habits normally, in order to discover if the abnormal values are repeated or not.
We must bear in mind, however, that our cholesterol level depends directly on our diet and our lifestyle, so if you have high cholesterol, one of the main recommendations given is to maintain a healthy diet low in fats, and exercise regularly.
