What is Cholesterol?

 

Cholesterol is a waxy substance. Your body needs it to build cells, to insulate nerves, and to produce certain hormones. But having too much cholesterol can increase your risk of heart disease and stroke.

Decreased blood flow to your brain can cause a stroke.

 

Most of the cholesterol in your body is produced by the liver. The rest comes from foods such as poultry, meat and dairy products.

 

There are different types of  cholesterol:

    Low Density Lipoprotein (LDL) Cholesterol: known as “bad” cholesterol as it raises your risk of heart disease, heart attack, and stroke.

 

     High Density Lipoprotein (HDL) Cholesterol: known as “good” cholesterol as it is linked to a lower risk of heart disease, heart attack and stroke.

 

High cholesterol can be inherited, but it's often the result of unhealthy lifestyle.

Lifestyle changes which can help:

If you already have plaques in your arteries, or your risk of having heart disease or stroke is very high, your doctor will normally recommend treatment with medications. ‘Statin’ is the medication most commonly used. Over the last 30-40 years, many studies involving thousands of patients have proven the effectiveness of statin in lowering the risk of heart disease and stroke in certain individuals.
