People with one symptom in their legs are being urged to take extra precautions before flying this spring.A medical expert has raised concerns about the risks that flying can pose for some people with varicose veins and blood clots.
Varicose veins, enlarged, twisted veins that often appear in the legs, are a common issue for many. Although they tend to be influenced by genetics, the symptoms can worsen during long-haul flights. While the act of flying itself doesn’t cause varicose veins, the combination of sitting still for long periods, reduced movement, and the change in cabin pressure can aggravate the condition, leading to swelling and discomfort in the legs.
Dr Peter Finigan, a clinical practitioner specialising in vascular medicine at the UK Vein Clinic, said: “Varicose veins are largely a genetic condition, but factors like prolonged immobility, which is common on long flights, can certainly make symptoms worse, leading to leg swelling and discomfort.”
When you’re sitting for extended periods, especially during flights, blood flow to your legs can be restricted. This poor circulation puts additional pressure on your veins, which can lead to pain and swelling. And changes in cabin pressure can also impair blood flow, potentially worsening existing vein issues and increasing the risk of blood clots.
“Cabin pressure fluctuations can make it harder for blood to flow freely, adding to the discomfort you may already be experiencing,” said Dr Finigan. “It’s not just about pain and swelling. In more severe cases, blood clots can form.”
How to stay comfortable and avoid complications
Dr Finigan has shared simple steps you can take to reduce the likelihood of developing symptoms and ensure that your journey is as smooth as possible.
- Move around regularly: “Take frequent breaks to get up, walk around, and stretch. Exercises such as ankle rotations and calf raises can help keep blood flowing to your legs.”
- Stay hydrated: “Dehydration can exacerbate vein issues, so make sure you’re drinking plenty of water throughout the flight. Avoid excessive alcohol or caffeine as they can dehydrate you.”
- Consider compression stockings: “These stockings apply gentle pressure to your legs, which helps to improve circulation and reduce swelling. They’re a practical option for anyone prone to varicose veins.”
Treatment options for varicose veins
If varicose veins are already a concern for you, Dr Finigan suggests exploring various treatment options. “Endovenous Laser Ablation (EVLA) is a minimally invasive procedure that uses laser energy to close off damaged veins, effectively addressing the root cause of the issue.”
For smaller veins, Foam Sclerotherapy is a common solution, where a foam solution is injected into the veins to close them off. Sometimes, a combination of both treatments is used to ensure comprehensive care.
If your veins are more severe, avulsion surgery may be recommended to physically remove the affected veins, which can often be done in conjunction with EVLA to achieve the best results. “Seeking treatment early is key,” Dr Finigan advises. “Not only does it alleviate symptoms, but it also reduces the risk of more severe complications, such as skin ulcers or long-term vein damage.”
