Going on a Trip? Understanding Deep Vein Thrombosis (DVT)
- 30 March 2025
What is Deep Vein Thrombosis (DVT)?
Deep vein thrombosis (DVT) occurs when a blood clot forms in a large (deep) vein in the leg. In some cases, part of the clot may break off and travel to the lungs, causing a sudden blockage of arteries in the lung. This condition is known as a pulmonary embolism (PE). While these conditions are rare, it’s important to understand their causes, risk factors, and prevention methods.
How Travel Increases Your Risk of DVT
Almost anyone can develop DVT, but long-duration travel can increase your risk. This is particularly true for air travel, where you’re confined to a small space and limited in movement. However, DVT can also occur during prolonged travel by bus, train, or car.
Travel Duration and DVT Risk
If you travel for more than four hours, whether by plane, train, car, or bus, you are at an increased risk of developing DVT.
Who is at Higher Risk for Travel-Associated DVT?
- A previous blood clot
- Family history of blood clots
- Known inherited clotting disorder
- Recent surgery, hospitalization, or injury
- Use of estrogen-containing birth control or hormone replacement therapy
- Current or recent pregnancy
- Age over 65
- Obesity
- Active cancer (or undergoing chemotherapy)
- Other serious illnesses, such as congestive heart failure or inflammatory bowel disease
How to Prevent DVT While Traveling
You can take simple steps to reduce your risk of developing DVT during travel:
- Move Your Legs and Feet: Raise your heels with your toes on the floor and get up to move around every hour.
- Stay Hydrated: Drink plenty of water, but avoid alcohol and caffeine.
- Wear Loose Clothing: Tight clothing can restrict blood flow.
- Avoid Sleeping Pills: These can keep you immobile for long periods.
- For Drivers: If you are driving, stop every hour and walk for a few minutes.
Recognising the Signs and Symptoms of DVT
Being aware of DVT symptoms can help you seek medical attention promptly.
Symptoms of a Leg Clot (DVT)
- Swelling, pain, or tenderness (usually in one leg)
- Skin that is red and warm to the touch
Symptoms of a Lung Clot (PE)
- Difficulty breathing
- Sudden shortness of breath
- Faster than normal heartbeat
- Chest pain (worsens with coughing or deep breathing)
- Coughing up blood
- Lightheadedness or fainting
When to Seek Medical Help
If you experience symptoms of DVT, contact a doctor immediately. If you have symptoms of a pulmonary embolism (PE), seek urgent medical care at a hospital.
By understanding DVT and taking preventive measures, you can travel more safely and reduce your risk of serious complications.
