It is important to note that during pregnancy, the plasma volume in your body increases up to 50%. This can increase the risk of blood clots in patients who remain stationary for long periods of time. Travel is allowed, but patients are encouraged to get up and move around periodically to help keep the blood volume circulating as permitted.
Flying also can cause mild dehydration. Dehydration can cause uterine cramping. When flying, please drink plenty of fluids and make sure that you stay hydrated!
