What You Should Know About Flying and Blood Clots

Blood clots, known medically as deep vein thrombosis (DVT), can occur in the deep veins of the legs or pelvis. While DVT can occur in anyone, some individuals are at higher risk of developing them. Here's what you need to know about flying and blood clots:

1. Risk of Blood Clots During Flights:

Prolonged sitting or immobility during long flights can increase the risk of developing DVT. This is because staying seated for long periods can reduce blood circulation in the legs, which may contribute to the formation of blood clots.

2. Factors Contributing to Increased Risk:

Certain individuals have an increased risk of DVT during flights, including:

a. People over the age of 40

b. Individuals with a personal or family history of blood clots

c. Pregnant women or women taking hormone replacement therapy (HRT)

d. Individuals undergoing surgery recently or with certain medical conditions

e. People who are obese or overweight

3. Preventive Measures:

To reduce your risk of DVT during flights, follow these preventive measures:

a. Get up and move around every 2-3 hours.

b. Flex your feet, ankles, and calves regularly while seated.

c. Wear loose-fitting, comfortable clothing.

d. Stay hydrated by drinking plenty of water.

e. Avoid excessive alcohol consumption.

f. If you're at a higher risk of DVT, consider compression stockings or consulting with your doctor for additional recommendations.

4. Recognizing Symptoms of DVT:

It's important to be able to recognize the symptoms of DVT, which may include:

a. Pain or tenderness in the calf or behind the knee

b. Swelling in the affected leg or ankle

c. Increased warmth in the affected area

d. Red or discolored skin on the affected leg

If you experience any of these symptoms, it's essential to seek prompt medical attention.

5. Precautions for Long Flights:

For long-haul flights, it's wise to take extra precautions:

a. Book an aisle seat to facilitate easier movement.

b. Consider using compression stockings if recommended by your doctor.

c. Avoid crossing your legs while sitting.

d. Try to stand in the aisle when the seatbelt sign is off.

e. Perform simple seated calf exercises, such as heel raises and toe touches.

Remember, while traveling by air can increase the risk of DVT, taking preventive measures and being aware of the symptoms can significantly reduce your risk and keep you safe during flights. If you have any concerns or underlying health conditions, consult with your healthcare provider before long-distance air travel.
