What is a blood clot? Day 1/31 #BloodClotAwarenessMonth
Blood clots stop bleeding when you’re injured. But if they form inside a vein or artery, they can block blood flow and cause DVT, PE, stroke or heart attack. Sudden leg swelling, chest pain or shortness of breath? Don’t ignore it.

Learn the key signs of deep vein thrombosis and pulmonary embolism on World Thrombosis Day. Early detection saves lives. A quick 60-second guide from a vascular surgeon in Singapore.
World Thrombosis Day — Blood Clots in 60 Seconds
Today is World Thrombosis Day. Here is a quick 60-second explainer on blood clots.
One in four people worldwide die from conditions caused by thrombosis. Blood clots often form silently, most commonly in the legs as a deep vein thrombosis (DVT). When blood flow slows — after surgery, long flights, illness or immobility — a clot can develop.
The danger is when a clot breaks loose and travels to the lungs. This is called a pulmonary embolism (PE). Together, DVT and PE are known as venous thromboembolism (VTE). Around 60% of VTE occurs in hospital, making it the leading preventable cause of hospital-related death.
In clinical practice, especially here in Singapore, vascular surgeons can remove the clot, restore blood flow, and prevent long-term damage using minimally invasive endovascular techniques. But awareness remains the key: recognising symptoms early saves lives.
Know the signs and symptoms of a blood clot:
• Leg swelling
• Pain or tenderness
• Leg discoloration
• Sudden shortness of breath
• Chest pain
• Fainting or feeling light-headed
• A racing heartbeat
If these symptoms appear, seek urgent medical attention.
