DVT Prevention: Simple Steps to Reduce Your Risk

DVT prevention: simple steps to lower your risk

Deep vein thrombosis (DVT) happens when a blood clot forms in a deep vein, usually in the leg. That clot can travel to the lungs and cause a pulmonary embolism — a medical emergency. You don’t need to be scared, but you should take clear steps to reduce your risk. Here are the practical, everyday things that work.

Know your personal risk. Age over 60, recent surgery, broken bones, cancer, pregnancy, hormonal birth control or HRT, obesity, smoking, and long periods of immobility raise the chance of DVT. If any of these apply, talk to your doctor about extra precautions before travel or surgery.

Move more and sit less

Sitting for hours is one of the easiest risks to fix. On long flights or drives stand up and walk every hour if you can. If you can’t get up, pump your ankles and wiggle your toes every 15–30 minutes to keep blood flowing. At home, short walks several times a day beat long sessions of sitting. Regular exercise — even brisk walking 30 minutes most days — helps circulation and cuts risk.

Use compression and follow medical advice

Compression stockings squeeze the leg gently and reduce blood pooling. They’re proven to help people who’ve had DVT before or who must stay immobile after surgery. Use the right size and wear them as directed. If your doctor prescribes blood thinners (anticoagulants) take them exactly as told — don’t stop suddenly. For short-term situations like after certain surgeries, low-dose heparin or aspirin may be advised. Ask your clinician which option fits your situation.

Small lifestyle changes add up. Stay hydrated during travel and illness — dehydration thickens blood. Drop smoking and aim for a healthy weight if possible; both reduce clot risk. Be cautious with over-the-counter hormone pills and ask about safer alternatives if you need them. When you have a cast or severe leg injury, ask your doctor if you need DVT prevention while you’re less active.

Recognize symptoms early. Pain, swelling, warmth, or redness in one leg are common DVT signs. Sudden shortness of breath, chest pain, or rapid heartbeat could mean a clot reached the lungs — seek emergency care right away. Don’t ignore milder leg symptoms; early testing and treatment prevent complications.

If you travel often for work, plan ahead. Choose aisle seats if possible, drink water, and set reminders to move. For long-haul flights, consider compression socks and speak with your doctor about temporary medication if you have multiple risk factors. Surgery patients should ask about blood clot prevention before and after the operation.
