March is Deep Vein Thrombosis Awareness Month. A deep vein thrombosis (DVT) is when a blood clot forms in one of the large veins, usually in the lower leg, thigh, pelvis, or arm. A blood clot can partially or completely block blood flow in the vein. When a DVT is left untreated, a part of the clot can break off and travel to the lungs, causing a blockage known as a pulmonary embolism (PE). 

In the United States, an estimated 900,000 people are affected by a blood clot every year, yet they are often underdiagnosed. It’s important to raise awareness about blood clots because they are serious medical conditions that can cause illness, disability, and even death.  Anyone can be affected, but certain risk factors, such as pregnancy, cancer and its treatment, and hospitalization can increase a person’s risk for a blood clot.

Although, a DVT or PE can occur with no symptoms, knowing the symptoms can help alert you to seek medical treatment as early as possible.

Common signs and symptoms of a DVT include:

• Swelling of the affected area,
• Pain,
• Tenderness, and
• Redness of the skin

If you have these signs or symptoms, alert your doctor as soon as possible.

Common signs and symptoms of a PE include:

• Difficulty breathing,
• Faster than normal or irregular heartbeat,
• Coughing up blood,
• Very low blood pressure, lightheadedness, or fainting

Seek medical attention immediately if you experience any of these signs or symptoms.
