The Risks of Blood Clots

A blood clot is known as deep vein thrombosis (DVT) and can be the result of surgery, an injury, certain genetic disorders, cancer, smoking, and obesity. Even sitting for a prolonged length of time can cause a clot to form because blood flow may be restricted during this time. Pregnant women are also susceptible to blood clots due to an increased level of estrogen and an expanding uterus.    

A blood clot that starts in your calf can break off and travel through the bloodstream to the lung. Once there, the clot can become stuck and and block the flow of blood, causing organ damage and even death. This is called a pulmonary embolism (PE). If you experience any of the symptoms below, call 911 or go the the emergency room immediately.  

Symptoms of a pulmonary embolism:

  • Shortness of breath
  • Rapid heart beat
  • A sharp chest pain that may get worse with deeper breaths
  • A cough that sometimes produces a bloody mucus
  • Fainting
  • Low blood pressure

Blood clots that are left untreated can spread to other parts of the body and lead to more serious problems. In fact, up to 100,000 people die each year from blood clots.

Fortunately, most blood clots are easily treated when found early. If you experience swelling, pain, discoloration, or unusual warmth in your calf, see a medical professional immediately.
