Deep vein thrombosis (DVT): symptoms, urgency, and treatment basics
A DVT is a blood clot in a deep vein, usually in the leg. It matters because part of the clot can travel to the lungs and cause a pulmonary embolism, so sudden breathlessness or chest pain is an emergency.
When to get urgent help
- Leg swelling with chest pain, shortness of breath, collapse, or coughing blood
- A suddenly painful, swollen leg with major clot risk factors
- Symptoms after major surgery, immobility, pregnancy, or cancer treatment
What to expect
- Doctors may use history, examination, D-dimer, and ultrasound to confirm the diagnosis.
- Treatment usually involves anticoagulation to stop the clot getting bigger and reduce recurrence risk.
- The treatment duration depends on why the clot happened and your future risk.
Simple self-care and follow-up points
- Seek urgent medical review rather than waiting if you think you may have a DVT.
- Know the warning signs of pulmonary embolism: chest pain, breathlessness, collapse, or coughing blood.
- If you are prescribed anticoagulants, take them exactly as directed and ask about bleeding precautions.
