Often, swollen ankles while flying is harmless and goes away on its own. In rare cases, ankle swelling may be a sign of deep vein thrombosis (DVT), which is more serious and requires medical treatment.

Studies show that edema is present in
In this article, we discuss the causes of swollen ankles while flying. We also outline other symptoms and provide possible prevention tips to consider before and during flying.
Swollen ankles during and after air travel may result from conditions such as a buildup of fluid and blood clots.
We discuss these causes in more detail below.
Leg edema from flying is
Venous thromboembolism (VTE) is a disease that occurs when blood clots
Factors that can cause DVT during flying include:
- lower limb immobility due to sitting for extended periods
- slow blood flow (venous stasis) through the veins in the legs due to inactivity
- reduced blood flow to the deep and superficial veins of the legs
The symptoms of swollen ankles from flying may depend on the underlying condition causing it.
Leg edema symptoms
If a person has swollen ankles due to leg edema, they may experience the
- the leg starts to feel full or heavy
- the leg starts to look swollen

- pain or tenderness around the affected area
- skin that is warm to the touch

If a person has symptoms of DVT, they should speak with a doctor.
This can cause a blockage in the blood vessels present in the lungs. This blockage is a PE.
If the clot is small, a person can recover with appropriate treatment. However, if the clot is large, it can stop blood from reaching the lungs, which can be fatal.
A person can develop PE even without any symptoms of DVT. Symptoms of a PE
- difficulty breathing
- a heartbeat that is irregular or faster than normal
- chest pain or discomfort that often worsens with deep breathing or coughing
- coughing up blood
A person should seek immediate medical help if they experience these symptoms.
If a person is worried about DVT while flying, they should speak to a healthcare professional. They can then understand which signs and symptoms to look out for.
Those who may be at higher risk of DVT when flying
- with a history of blood clots
- with a family history of blood clots
- who have recently had surgery
- who are pregnant
- who are taking certain medications, such as hormone replacement therapy and contraceptive agents
A person can
These stockings work to improve blood flow in the legs during flying. They exert the greatest degree of compression at the ankle. The level of compression gradually decreases up the garment.
There are a number of steps a person can take to decrease their risk of edema and DVT while flying. These
- Move the legs frequently when on long flights by walking up and down the cabin.
- Exercise the calf muscles to improve the flow of blood.
- Avoid sitting down for too long a period of time.
- If a person has been sitting for a long time, they should take a deep breath and stretch their legs.
