Blood clots

Find a symptom by its first letter

Definition

Blood clots are gel-like clumps of blood. They are beneficial when they form in response to an injury or a cut, plugging the injured blood vessel, which stops bleeding.

Some blood clots form inside your veins without a good reason and don’t dissolve naturally. These may require medical attention, especially if they are in your legs or are in more critical locations, such as your lungs and brain. A number of conditions can cause this type of blood clot.

Causes

Blood clots form when platelets (blood components) and plasma proteins thicken, forming a semisolid mass. This process may be triggered by an injury or it can sometimes occur inside blood vessels that don’t have an obvious injury.

Once these clots form, they can travel to other parts of your body, causing harm. Factors and conditions that can cause troublesome blood clots, as well as serious conditions that are associated with blood clots, include:

  • Antiphospholipid syndrome
  • Arteriosclerosis / atherosclerosis
  • Certain medications, such as oral contraceptives, hormone therapy drugs and some breast cancer medications
  • Deep vein thrombosis (DVT)
  • Factor V Leiden
  • Family history of blood clots
  • Heart arrhythmias
  • Heart attack
  • Heart failure
  • Obesity
  • Peripheral artery disease
  • Polycythemia vera
  • Pregnancy
  • Prolonged sitting or bed rest
  • Pulmonary embolism (blood clot in an artery in the lung)
  • Smoking
  • Stroke
  • Surgery
