What is Atherosclerosis?

Your arteries are the carriers of blood from your heart to all the parts of your body. Generally, these arteries are flexible and elastic. But in atherosclerosis, your arteries become thick and sti...


Because atherosclerosis develops gradually, symptoms do not get displayed until the situation gets worsened and complicated. It might result in an inadequate supply of blood to organs and tissues. Symptoms also depend on:

  • The location of the affected artery.
  • Heart pressure in the chest and chest pain
  • Brain –numbness and weakness in arms and legs, slurred speech, drooping facial muscles, and temporary loss of vision in one eye
  • Arms and legs – Leg pain during physical activities
  • Kidneys – High blood pressure or kidney failure


Atherosclerosis is thought to begin with a small damage or injury caused to the thin inner layer of an artery called endothelium. The causes could be:

  • High amount of triglycerides
  • High cholesterol
  • Consumption of tobacco
  • High blood pressure
  • Obesity or diabetes
  • Arthritis, lupus, infections and other inflammatory diseases


Atherosclerosis happens due to several risk factors like ageing, lack of physical activities, obesity, diabetes, consumption of unhealthy food, high blood pressure and cholesterol, family history of heart disease, etc.


Lifestyle changes like quitting smoking and excessive consumption of alcohol and maintaining a healthy weight by regular exercising and healthy dietary food are to be incorporated to prevent atherosclerosis.

  • Antiplatelet medication

    Tablets like aspirin may be prescribed to avoid clotting of blood in the blocked areas

  • Cholesterol medication

    By decreasing the cholesterol levels in your blood, you can stop the building up of plaques in your arteries.

  • Beta-blocker medication

    These are used to lower blood pressure and relieve symptoms of chest pain

  • ACE Inhibitors

    Using angiotensin converting enzyme inhibitors, blood pressure is reduced, along with the risk of recurrent heart attacks

  • Angioplasty

    Using a deflated balloon attached to a slender catheter, the narrowed blockages are shattered in this method. This happens when the balloon is inflated.

  • Endarterectomy

    Surgical removal of plaques.

  • Bypass surgery

    Creating a bypass route for the flow of blood, by avoiding the usage of the narrowed artery

  • Fibrinolytic therapy

    Drugs that dissolve clots are administered
