How to Manage Venous Insufficiency During Long Flights

Exploring new places is one of life’s great joys, but if you live with chronic venous insufficiency (CVI), sitting for long periods on a plane or in a car can make your symptoms worse and increase your risk of blood clots.

At Carolina Vein Institute, with offices in Chapel Hill, Raleigh, and Apex, NC, our vein specialists provide advanced diagnosis and treatment for venous insufficiency and varicose veins. Using the latest minimally invasive techniques, we can help you restore healthy circulation and prepare for safe, comfortable travel.

What is venous insufficiency?

Venous insufficiency occurs when the valves inside your leg veins become damaged or weakened, making it harder for blood to flow upward toward your heart. Instead, blood can pool in the legs, leading to symptoms such as:

• Leg swelling
• Heaviness or aching
• Visible varicose veins

CVI may develop due to deep vein thrombosis (DVT), where a blood clot forms in a deep vein and leaves behind scar tissue that interferes with normal valve function. Some people may also be born with vein abnormalities that affect blood flow.

Over time, this chronic pooling of blood can cause discomfort, skin changes, or even ulceration — making proactive vein care and travel precautions especially important.

5 tips to protect your vein health when traveling

If you have venous insufficiency or are at risk, take these simple steps to support circulation and reduce the likelihood of swelling or clots during long trips:

1. Stay well hydrated

Drink plenty of water before and during travel to keep your blood flowing smoothly. Limit alcohol before and during flights, as dehydration can increase clotting risk.

2. Move frequently

During flights, stand up and walk around the cabin every couple of hours. On long drives, schedule regular stops to stretch your legs and move your body.

3. Wear compression stockings

Graduated compression socks help promote upward blood flow and prevent fluid buildup in your legs. Wearing high-quality compression garments during travel can significantly reduce swelling and discomfort.

4. Choose comfortable clothing

Avoid tight pants or waistbands that restrict circulation. Opt for loose, breathable fabrics that allow you to move and sit comfortably during extended travel.

5. Schedule a pre-travel vein evaluation

Before a long trip, especially if you’ve experienced leg pain, swelling, or varicose veins, consider a checkup with our vein care team. We can assess your circulation, discuss your risk for blood clots, and recommend any preventive treatments or compression therapy if needed.

Scheduling this visit several weeks in advance allows time for any necessary medications, procedures, or follow-up care before your departure.

Plan ahead for healthier travel

Whether you’re flying across the country or heading overseas, taking proactive steps to support your vein health can make all the difference in your comfort and safety.
