  • High blood cholesterol

Cholesterol (cholesterol) is a compound found in every cell of the body, and it uses it to build new and healthy cells, and to produce hormones that are essential to it.

If the level of cholesterol in the blood is high, this means that fatty deposits will form within the walls of blood vessels, and these deposits will ultimately impede the flow of blood in the arteries.

What happens when high cholesterol?
High cholesterol level in the body affects through:

The blood will not get the amount of oxygen-rich blood it needs, which will increase the likelihood of a heart attack.
Failure of blood to reach the brain properly may lead to a stroke (or: a stroke – a cerebralstroke).
Symptoms of high cholesterol
There are no symptoms of cholesterol or signs of hypercholesterolemia (hypercholesterolemia).

It is only possible to detect high cholesterol values ​​by having a blood test.

Causes and risk factors of high cholesterol
Causes and risk factors of cholesterol

Cholesterol moves through the blood vessels by binding to certain proteins in the blood.

This fusion of proteins and cholesterol is called “lipoprotein” (or: lipoprotein) in medical language.

Types of cholesterol
There are three different types of cholesterol, according to the type of lipoprotein:

Low density lipoprotein – LDL:
It is he who transports cholesterol particles into the body. LDL cholesterol (the bad cholesterol) builds up on the walls of your arteries, making them stiffer and narrower.
Very – low – density lipoprotein – VLDL:
This type of lipoprotein contains the largest amount of triglycerides, a type of lipids that bind to proteins in the blood. Cholesterol particles build up and make them larger, which leads to narrowing of blood vessels.
If you are taking medicines to lower your cholesterol level in your blood, but your blood test results show an elevated level of VLDL, then you likely need additional medicine to lower the level of VLDL cholesterol in your blood, because VLDL is very rich in triglycerides.

High-density lipoprotein HDL:
It is he who collects the redundant amounts of cholesterol and returns it to the liver.
Controlled factors that affect cholesterol
There are many factors under your control that contribute to raising the level of bad cholesterol – LDL on the one hand, and reducing the proportion of good cholesterol – HDL on the other hand, and the most important of which are:

Lack of physical activity
Improper and unbalanced feeding.
Factors not under control
There are other factors that are not under your control that may constitute an additional factor in determining the level of cholesterol in your blood, such as

Genetic factors: These can prevent the body’s cells from effectively removing excess LDL cholesterol in the blood or causing the liver to produce excess amounts of cholesterol.
If you belong to one of the risk groups: You will likely suffer from high levels of cholesterol that could lead to heart disease, and these groups are:
Smoking: Cigarette smoking damages the walls of blood vessels, making them more likely to accumulate fatty deposits inside them. In addition, smoking can lower your levels of good HDL cholesterol.
Overweight: If your body mass index (BMI) is higher than 30, the risk of high cholesterol may also increase.
Malnutrition: Cholesterol-rich foods, such as red meat and high-fat dairy products, raise the level of total cholesterol in the blood. Eating saturated foods (which come from animals) and trans fats (which are found in processed foods such as cakes and chips) may increase the level of cholesterol in the blood.
Not engaging in physical activity: Physical activity helps the body to raise the level of good HDL cholesterol and reduce the level of harmful LDL cholesterol. Insufficient physical activity increases the risk of high cholesterol.
High blood pressure: High blood pressure on the walls of the arteries damages the arteries, which can speed up the process of accumulation of fatty deposits inside them.
Diabetes: High levels of sugar in the blood lead to higher values ​​of LDL cholesterol – bad cholesterol and lower values ​​of HDL – good cholesterol. Also, high blood sugar levels may damage the inner coating of the arteries.
Family patients: If a parent or sibling had suffered from heart disease before reaching the age of 50, high levels of cholesterol raise the risk of heart disease above the general rate.
Complications of high cholesterol
Cholesterol complications

High levels of cholesterol can lead to atherosclerosis, which is a dangerous buildup of cholesterol and other deposits on the walls of your arteries.

These deposits, called plaques, may reduce the amount of blood flowing in the arteries.

If it is the affected arteries that deliver blood to the heart (coronary arteries), chest pain (angina) and other symptoms that characterize atherosclerosis are likely to develop.

If the plaque deposited from the walls of the arteries is ruptured or removed, a blood clot may result at the site of the tear, which may impede blood flow, or the clot may separate and block another artery.

The blood supply to the heart stops leads to a heart attack. As for the suspension of the blood supply to the brain, it leads to a stroke.

Diagnosis of high cholesterol
A blood test that measures the level of cholesterol in the blood (a lipid profile), called a lipids panel (or: a lipid profile) usually shows:

Level A.
