If you are planning a flight of more than four hours during pregnancy I recommend the following precautions to reduce the risk of blood clots including:
- drink plenty of water;
- avoid things that dehydrate you, including alcohol and caffeine;
- wear thigh-length surgical stockings during the flight;
- walk up and down the aisle every hour and wiggle your toes when you are seated, to keep the blood circulating;
The ideal time to travel is between 20 and 30 weeks gestation. Most airlines are happy for you to fly until 34 weeks and some airlines are happy for you to fly until 36 weeks. Most will require a doctor’s letter after 24 weeks, so you should arrange to see me for a check soon before you depart.
Be careful with exotic locations in pregnancy, as there may be a malaria risk and malaria prevention can be more complex in pregnancy.
