Blood fat (fat in the blood) is called lipid.
Lipid is a fatty compound that performs many important functions in the body. However, it is useful in normal amounts, as the risk of heart attack and stroke increases with overdose.
Since lipid is a component of cell structure, it is present in all areas of the body.
In order to check the amount of fat in the blood, the doctor orders a laboratory study - a blood sample determines the level of lipids.
For information, the level of triglycerides varies during the day and increases after a meal, therefore, a blood test must be performed after 12 hours of fasting. For accurate results, it is recommended that a person does not take medication before the analysis. The analysis should not be performed when the person is under stress or feeling unwell.
The course of treatment for excess lipids is individual and depends on the specific clinical case, for example, lifestyle changes or drug therapy may be necessary.
Sometimes, to normalize the level of fat in the blood, it is necessary to lose excess weight, give up tobacco, limit alcohol.
Sometimes a specific medication is prescribed, the main purpose of which is to prevent the formation of cholesterol in the liver.
In some clinical cases, the goal of drug therapy is to remove excess cholesterol.
