Blood clots: know what to look for as a patient
Blood clots can happen to anyone. Your risk may be higher during certain times in your life or because of things like surgery, pregnancy, being less active, some illnesses or certain medications.
Knowing your risk and recognizing the warning signs can help you get care when you need it.
World Thrombosis Day helps people understand blood clots, know the signs and take steps to protect their health.
Support better conversations about blood clots
Healthcare professionals play a key role in preventing, recognizing and treating blood clots. Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), can affect patients across every medical specialty.
Risk can increase with surgery, prolonged immobility, cancer, pregnancy and certain medications. Recognizing risk early and taking appropriate steps to prevent and detect blood clots can help protect patients and improve outcomes.
World Thrombosis Day provides resources to support healthcare professionals in raising awareness, preventing thrombosis and recognizing blood clots early.
Know the risks. Recognize the signs. Take action.
