Blood Clots in Varicose Veins

Blood clots can form in varicose veins in some instances, so if you have varicose veins, you are at risk of these types of blood clots. This condition is called Superficial Vein Thrombosis.

Have Your Varicose Veins Treated Prior to Getting on a Flight

Steps to Take While on a Flight

Once your varicose veins are gone, you can rest assured that your risk will be decreased, but there are still other steps you can take to prevent other types of clots while on a long flight.

  • Avoid taking sleeping pills, which can result in immobility

  • Massage your calves regularly, and move your toes frequently
  • Only sleep for short periods of time, preferably no longer than a half hour at a time
