What Is Deep Vein Thrombosis (DVT)?

DVT occurs when a blood clot forms in a deep vein, typically in the lower legs or thighs. These clots can partially or completely block blood flow and, if dislodged, may travel to the lungs—causing a life-threatening pulmonary embolism (PE).

Common DVT Symptoms Include:

  • Swelling in one leg
     
  • Pain or tenderness, especially when standing or walking
     
  • Warmth or redness over the affected area
     
  • Leg cramps, often starting in the calf
     

However, DVT can also be silent, meaning some people may not experience noticeable symptoms. That’s why prevention and awareness are crucial—especially while traveling.

 

Why Long Travel Increases DVT Risk

Extended periods of sitting—whether on a plane, in a car, or on a train—can restrict blood flow in the lower extremities. When the legs remain still for too long, blood pools in the veins and increases the risk of clot formation.

Factors that elevate DVT risk during travel include:

  • Flights longer than 4 hours
     
  • Dehydration due to low cabin humidity
     
  • Pressure changes at high altitudes
     
  • Limited legroom reducing circulation
     
  • Crossing legs for prolonged periods

Who Is at Risk?

Not everyone faces the same risk while traveling. According to Dr. Rahul Agarwal, individuals with the following conditions should be particularly cautious:

  • History of DVT or pulmonary embolism
     
  • Family history of clotting disorders
     
  • Recent surgery or hospitalization
     
  • Obesity
     
  • Pregnancy
     
  • Cancer or ongoing cancer treatment
     
  • Smoking
     
  • Use of hormone therapy or birth control pills
     

If you're unsure about your risk, it’s advisable to consult a vascular surgeon before any long journey.

Expert Tips to Prevent DVT During Travel

1. Move Around Regularly

Get up and walk at least once every hour. On a flight, walk down the aisle or perform in-seat leg stretches. If you’re in a car, take a break every 1–2 hours to walk and stretch your legs.

2. Wear Compression Stockings

Graduated compression stockings help promote healthy blood flow in the legs. Dr. Rahul Agarwal recommends compression wear for patients at moderate to high risk of DVT, especially during long (>4 hours flight) air travel.

3. Stay Hydrated

Drink plenty of water before and during your trip. Dehydration can thicken your blood and increase clotting risk. Avoid alcohol and caffeine, which can dehydrate the body.

4. Avoid Crossing Legs

Crossing your legs for long periods can compress veins and reduce circulation. Keep your feet flat on the floor and shift positions regularly.

5. Dress Comfortably

Tight clothing, especially around the waist and legs, can restrict blood flow. Choose loose-fitting, breathable attire for long trips.

6. Perform Simple Leg Exercises

Every 30 minutes, try:

  • Ankle circles
     
  • Calf raises
     
  • Toe lifts
     
  • Knee-to-chest stretches
     

These movements improve circulation and reduce the chance of blood pooling.

7. Consider Preventive Medication

For high-risk individuals, Dr. Rahul Agarwal may prescribe a low-dose blood thinner (anticoagulant) before travel. Never self-medicate—always consult your doctor.
