Why regular cholesterol screenings are important?

  • Cholesterol: A waxy, fat-like substance that’s found in all the cells in your body.
  • Importance of cholesterol: make hormones, vitamin D, and substances that help you digest foods.
  • Where it comes from: Mostly our body makes it as per our requirement but even from some external sources like eggs, meat, cheese etc. we derive it.


a. HDL stands for high-density lipoprotein. It is called “good” cholesterol because it carries cholesterol from other parts of your body back to your liver. Then, your liver removes the cholesterol from your body.

b. LDL stands for low-density lipoprotein. It is called “bad” cholesterol because a high LDL level leads to the buildup of plaque in your arteries.

c. VLDL stands for very low-density lipoprotein. Some people also call VLDL a “bad” cholesterol because it too contributes to the buildup of plaque in your arteries. But VLDL and LDL are different – Mainly VLDL carries triglycerides and LDL mainly carries cholesterol.

  • Common Cause: Unhealthy eating habits, Lack of physical activity, Smoking, Age, Heredity, Weight, Race, Weight.
  • Problem associated with Cholesterol: If you have too much cholesterol in your blood, it can combine with other substances in the blood to form plaque. Plaque sticks to the walls of your arteries. This buildup of plaque is known as atherosclerosis. It can lead to coronary artery disease, where your coronary arteries become narrow or even blocked.
  • Special case: Genetics may also cause people to have high cholesterol. For instance, familial hypercholesterolemia (FH) is an inherited form of high cholesterol. Certain medicines and other medical conditions may also cause high cholesterol.
