Why would flying cause a blood clot.?

Question

Surgery 10 days prior to flying but ok'd by Dr.

Answer 1

Long periods of inactivity while travelling in a plane may have serious consequences for some travellers. Blood clots in the legs known as Deep Vein Thrombosis (DVT) have been linked with long distance travel for many years but experts have been divided as to the extent and seriousness of the problem. Recently however a team of scientists from London has shown that up to 1 in 10 people over the age of 50 may develop a small clot in the calf during long-haul flights.

The formation of these blood clots is largely the result of the long periods seated in the aeroplane without moving. Being inactive for several hours causes the veins in the leg to stretch. This allows blood to pool in the veins and small clots to form. Although in the majority of people these clots dissolve harmlessly during the days after landing, for some people particularly those more at risk of blood clots (people over 50 years old those having had recent surgery or those with a serious illness) they can be dangerous. However, you can lessen your chances of developing Deep Vein Thrombosis by following these simply guidelines:

Before Travel

1. Discuss any pre-existing medical conditions with your doctor
2. Buy a pair of fitted compression stockings (e.g. Mediven Travel)
3. Avoid large amounts of alcohol before the flight
4. Avoid sedatives that may make you less mobile during the flight
On the Airplane:

1. Wear the fitted compression stockings
2. Every hour exercise the calf muscles either by bending your feet up and down whilst in the seat.
3. Drink half a litre of water every hour
4. Avoid drinking too much alcohol

Answer 2

Where was the clot? Most clots associated with flying occur in the legs because you're in economy class where there is less space than in a sardine can. Your knees are flexed and blood pools in the veins, leading to clot formation. When flying, make a conscious effort to flex and extend your arms and legs every 10 - 15 minutes, taking deep breaths as you do so. This helps squeeze blood out of certain veins and back to the heart. This is especially important for older individuals.

Clotting is a greater risk for people with certain diseases or conditions. One example is sickle cell trait.

Answer 3

It's the sitting in a confined space that causes the blood clot.
Make sure you move your feet and legs frequently to kepp the circulation going.

Answer 4

The change in air pressure and having to sit in one position for long periods of time.
