What is Cholesterol?

The liver makes cholesterol, a natural fatty substance that the body needs. When we consume animal source foods, we add additional cholesterol to our body.

It is classified in:

Good cholesterol or HDL cholesterol: its purpose is to remove cholesterol from the arteries and return it to the liver.
Bad cholesterol or LDL cholesterol: if there is a large amount of cholesterol in the blood, the excess sticks and forms plaques in the arteries, generating a progressive narrowing that over time can lead to atherosclerosis.

Signs and symptoms Cholesterol

What are the normal levels of cholesterol and triglycerides?

Total cholesterol: between 200 and 240 mg/dl
LDL cholesterol: between 100 and 160 mg/dl
HDL cholesterol: more than 35 mg/dl in men and 40 mg/dl in women

Risks

Diseases such as diabetes and obesity are determining factors in cholesterol levels, as are leading a sedentary life and consuming alcohol in excess. Age, sex, and family history also play a role.

Prevention

Adopting healthy habits will help you control your cholesterol level:

Follow a low calories, low-fat, and low salt diet.
Maintain a healthy weight.
Exercise regularly.

In the event that despite making changes in your lifestyle, cholesterol levels do not decrease enough, your ABC doctor will indicate a drug treatment to achieve it.

Diagnosis and treatment Cholesterol

An elevated cholesterol level has no signs or symptoms, so it is necessary to have a total cholesterol test and assess the risk of developing heart disease. This blood test considers and measures the following types of fat:

Total cholesterol
High-density lipoprotein cholesterol (HDL)
Low-density lipoprotein cholesterol (LDL)
Triglycerides

Patients who have had heart attacks or strokes require regular cholesterol testing to monitor the effectiveness of their treatment.
