Blood Thinner

A blood thinner, is such a drug that is used to prevent blood clots from forming or to lengthen the time that it takes for blood clots to form. These drugs are often used by people who are at risk for heart attack, stroke or heart disease. The most common blood thinner is Aspirin, an antiplatelet drug that has been recognized as a blood thinner worldwide

Reasons, Occurrence and Risk factors

Blood is a liquid that flows within blood vessels. Blood clotting is an important mechanism which freezes in the veins and interrupts circulation in the heart and brain.

The risk factors for blood clots are those that are common to all diseases that cause narrowing of blood vessels, cholesterol plaque formation, cerebral hemorrhage, heart attack, stroke and plaque rupture.

The risk factors which are major causes to Blood Clots:


The blood clots in veins do not allow blood to return to the heart and symptoms occur because of this damming effect. The symptoms are

Swelling in the Arms and Legs
Redness in the area
Warmth in the area

Arterial Blood Clots

Other symptoms depend upon the location of the clot, and often the effect will be a loss of function. Heart attack and stroke are self-explanatory.

In an arm or leg, in addition to pain, the limb may appear white, and weakness, loss of sensation, or paralysis may occur. People may face heart attack or severe stroke and due to that fainting and sweating is possible.

If the blood supply is lost to an area of the bowel, in addition to intense pain, there may be bloody diarrhea.

Signs and Tests

There are the various ways to find blood clots in the body in the veins and the arteries.

There are following ways to find out the blood clots:

  • Ultrasound: Venous blood clots may be detected through this test.
  • X ray: Through this test the radiologist can find out any blood clot in the vein.
  • ECG: Medically known as Electro- Cardiogram may show abnormalities suggestive of a pulmonary embolus and also may reveal other causes of chest pain such as blood clots.
  • C.T. Scan: This scan is often the test of choice when suspicion of pulmonary embolus is high. Contrast material is injected intravenously, and the radiologist can determine whether a clot is present in the pulmonary vessels or in the head to look for bleeding.
  • V Q Scan: This scan is performed to look for pulmonary emboli. This test uses labeled chemicals to identify inhaled air into the lungs and match it with blood flow in the arteries


These are some of the ways by which blood clots can be prevented:

  • Wear loose-fitting clothes, socks, or stockings
  • Raise your legs 6 inches above your heart from time to time.
  • Wear special stockings (called compression stockings) if your doctor prescribes them
  • Do exercises your doctor gives you.
  • Change your position often, especially during a long trip.
  • Do not stand or sit for more than 1 hour at a time.
  • Eat less salt.
  • Try not to bump or hurt your legs and try not to cross them.
  • Do not use pillows under your knees.
  • Take all medicines the doctor prescribes you
  • Living a stress free life
  • Taking a healthy diet and drinking more water


To treat blood Clots people generally take blood thinners which may be taken orally or by injection.

  • Heparin
  • Non-steroidal anti-inflammatory drugs (NSAIDs)
  • Thrombolytic
  • Warfarin
