Symptoms of a Leg Blood Clot

What causes leg blood clots?

Blood clots are normally formed as part of the natural process through which the body stops bleeding.  However, blood clots that form in the veins and don't dissolve on their own can be dangerous or even life-threatening.  A clot that is stuck in the veins could cause a medical emergency if it breaks free and obstructs blood flow in the heart or lungs.  Blood clots in one of the major arteries of the legs can cause a condition known as Deep Vein Thrombosis (DVT).  DVT blood clots are responsible for almost 100,00 deaths per year in the US.    

What are the symptoms of a Leg Blood Clot?

Blood clots can cause symptoms such as swelling, pain, tenderness, an unusual warm sensation, redness, or discoloration.  The symptoms can range in severity depending on the size of the clot and some people may not experience any unusual symptoms.  People who have a history of irregular blood clots should follow up with their doctors right away if they experience any unusual symptoms. 

What are the risk factors for Leg Blood Clots?

Conditions that can increase your risk of developing blood clots include:

  • Being over 65 years of age
  • Sitting down for long periods of time
  • Lying down for long periods of time
  • Obesity
  • Pregnancy
  • Smoking
  • Cancer
  • Some types of birth control medication
  • Inherited disorders.
  • Recent injuries, surgery, or lengthy hospital stays

How do I test for Leg Blood Clots?

Diagnosing a blood clot will require a doctor's examination.  There are a variety of blood tests that can evaluate a person's risk for clotting disorders.  The Protein C and Protein S tests measure proteins that are essential for the normal clotting process.  Deficiency in these proteins can cause DVT and other irregular clotting disorders.  A D Dimer test can come back elevated if a person is developing blood clots more than normal.   People who are at risk of frequent blood clots often take blood-thinning medication.  Tests such as the PT INR and PTT can help ensure their dosage is correct to avoid needing disorders.  Any irregular test results should be followed up with a person's doctor.
