Blood Clots on Flights: How Common Are They?

Blood clots, also known as deep vein thrombosis (DVT), are a serious medical condition that can occur when blood clots form in the deep veins of the legs. While DVT can occur in anyone, it is more common in people who are immobile for long periods of time, such as during long flights.

The risk of developing a blood clot on a flight is relatively low, but it does increase with the duration of the flight. For example, a study published in the journal JAMA Internal Medicine found that the risk of developing a DVT on a flight that was more than 8 hours long was about 1 in 1,000.

However, it is important to note that the risk of developing a blood clot on a flight is also influenced by a number of other factors, including:

• Age: The risk of developing a blood clot increases with age.
• Weight: People who are overweight or obese are more likely to develop a blood clot.
• Smoking: Smoking increases the risk of developing a blood clot.
• Recent surgery: People who have recently had surgery are more likely to develop a blood clot.
• Family history of blood clots: People who have a family history of blood clots are more likely to develop a blood clot.

If you are at high risk for developing a blood clot, you should talk to your doctor about taking precautions before you fly. These precautions may include:

• Wearing compression stockings: Compression stockings help to improve circulation in the legs and reduce the risk of blood clots.
• Taking aspirin: Aspirin is a blood thinner that can help to prevent blood clots.
• Getting up and moving around every few hours: Getting up and moving around helps to improve circulation in the legs and reduce the risk of blood clots.

If you experience any of the following symptoms during or after a flight, you should seek medical attention immediately:

• Pain or swelling in the legs
• Redness or warmth in the legs
• Shortness of breath
• Chest pain

Blood clots can be a serious medical condition, but they are preventable. By taking the necessary precautions, you can reduce your risk of developing a blood clot on a flight.
