Planning on travelling overseas this coming holiday season? Don’t forget to pack your compression socks to avoid Deep Vein Thrombosis (DVT).
What is DVT?
DVT happens when a blood clot forms in a deep vein somewhere in the body. It is most common in the deep veins of your lower leg (calf), and can be very serious.
There is evidence that long-haul flights (lasting over four hours or over 4000 kms) can increase your risk of developing DVT. The risk is mainly the result of sitting down for long periods of time, which can happen during any form of long-distance travel, whether by car, bus, train or air.
Symptoms
Many of the blood clots that cause DVT are small and don’t produce any symptoms. Your body will usually be able to gradually break them down with no long-term effects.
Larger clots can partly or completely block the blood flow in your vein and cause symptoms such as:
- Swelling of the affected leg.
- Pain and tenderness in the affected leg
- Difficulty standing and weight bearing on the affected leg.
- A change in the colour of your skin; for example, redness
- Skin that feels warm or hot to the touch.
