What Causes Deep Vein Thrombosis?


Deep vein thrombosis, or DVT, sometimes happens for no reason at all. However, the risk of DVT is significantly increased due to certain factors. These factors include:

  1. Immobility

When you are not being active, your blood will tend to gather and collect itself in the lower parts of your body or your legs. When you start moving again, your blood will flow evenly onto the different parts of your body.

Being immobile for a long time, for different reasons, will be a huge cause of this condition. Your blood flow will start to decrease significantly which can cause viscosity and then the formation of blood clots.

Immobility due to hospitalization

People who are in the hospital due to a disease or operation has a higher risk of developing DVT because they don’t move their limbs often, hence being less active.

As a patient, your risk would depend on what time of condition and treatment you have and are having. You may be at a higher risk for development of DVT if you are any of the following:

  • Having an operation that takes more than 90 minutes, in the leg, hip, or your abdomen.
  • You are having an operation for an abdominal or inflammatory condition.
  • You are confined and restricted for bed rest, unable to walk, or spending a large amount of time in a chair, sitting, for at least three consecutive days.

  1. Damage in the blood vessel

If the wall of your blood vessel becomes weakened and damaged, it may become blocked which can cause blood clots.

  1. Medical and genetic conditions

If you have a condition that predisposes you to form blood clots more easily, then you are at a higher risk of developing Deep vein thrombosis.  These conditions include:

  • Cancer
  • Infectious diseases
  • Lung and heart disease
  • Inflammatory conditions
  • Thrombophilia
  • Hughes syndrome – when your blood becomes sticky

  1. Pregnancy
  2. Contraceptive
  3. Others – smoking, obesity, dehydration, being over 60
