Normal cholesterol is a guarantee of heart health. Not many know how to determine that this indicator has exceeded the scope and the person needs treatment. What level is considered normal and for what symptoms you can identify the deviation, you will learn from the review presented.
Symptoms of high blood cholesterol
A substance similar to fats( lipophilic alcohol), is a part of cell membranes of living organisms. With food, a person gets only a small part of it, the rest of the cholesterol is synthesized by internal organs. Without the participation of this component, such important processes as digestion, the production of hormones, the synthesis of nutrients will become impossible. If LDL cholesterol is increased, it threatens the development of serious heart diseases( atherosclerosis, heart attack, ischemia).
Symptoms of increased cholesterol are as follows:
- Disorders of lipid metabolism.
- Appearance of specific nodes over tendons.
- Memory impairment.
- Thrombosis of blood vessels.
- The formation of the corneal lipoid arch( if the blood cholesterol level in women is exceeded after 50 years).
- Xantelasm( nodules of a dirty-yellow shade under the upper layer of the epithelium of the eyelid).
- Angina pectoris.
- Tenderness of the lower extremities under intense loads.
Analysis for cholesterol
Many people have an idea about the consequences of high cholesterol symptoms: among them are diseases that are life-threatening. Low-density cholesterol is the most harmful because of the ability to easily enter the arteries and form plaques on the walls. For the norm take different grades, it depends on the age of the patient. Some people mistakenly believe that the lower the level of this substance, the better for human health, but this statement is not entirely true, because HDL-cholesterol is involved in fat metabolism, normal functioning of the genital organs, and the construction of membranes.
It is not worthlessly trying to reduce the content of this substance, so as not to cause new problems. It is better to think about how to bring cholesterol back to normal: for this purpose, a general blood test is administered. It is worth noting that cholesterol in pregnant women can be twice the norm, which does not indicate deviations. The organism of the future mother works more intensively to provide the baby with the necessary nutrients. In the presence of such circumstances, the transcript of the blood test for cholesterol should not frighten the patient.
Symptoms of elevated cholesterol reveal a lipid profile that shows the following:
- low-density lipoproteins( LDL);
- high-density lipoproteins( HDL);
- triglycerides( TG).
In addition to a special study, the level of cholesterol, glucose, bilirubin, protein, electrolytes and enzymes in the blood can be determined by biochemical analysis. In old age the norm of bad cholesterol( ldl) rises, and the good decreases. If there are compelling reasons to worry, patients are prescribed a drug to normalize the indices of this substance - statin, in addition, reduce the daily volume of products with its content.
How to hand over
To determine how much this substance contains human blood, the method of laboratory research of the known scientist Abel helps. To obtain reliable information, the patient should prepare for the study:
- Avoid intensive physical exertion.
- Do not eat greasy and heavy foods.
- Give blood from a vein on an empty stomach.
Failure to follow these rules will lead to erroneous analysis, misdiagnosis and other problems. Fractions are determined by photometry and precipitation. This is a very laborious, but sensitive, specific and accurate way of laboratory research. However, the normative indicators differ in each laboratory, therefore it is impossible to give figures on which it is possible to be equaled.
What is the norm of human cholesterol
There are average norms that do not change with the years, for example, hemoglobin or sugar in the blood. The normal level of cholesterol is constantly reviewed by physicians who do not give specific figures, because the studies of cardiology are progressing and constantly give out new information. If 30 years ago the norm was 6-6.5 mmol / l, now it is not more than 4.5.
Women
| age | indices( mmol / L) |
|---|---|
| up to 25 years | 3,2-5,5 |
| 25-35 years | 3,4-6 |
| 35-45 years | 3,8-6,5 |
| 45-55 years | 4,2-7,4 |
| 55-70 years | 4,4-7,7 |
| over 70 | 4,5-7,2 |
For men
| age | indices( mmol / l) |
|---|---|
| up to 30 years | 3.6-6.6 |
| 30-40 years | 3.8-7.0 |
| 40-50 years | 4.0-7.2 |
| after 50 | 4.1-7.3 |
