• It is important to seek the advice of your doctor before planning any extensive travel, particularly overseas trips involving air travel.
• If you have experienced problems such as a history of miscarriage, gestational diabetes or you are having twins or triplets, your doctor may recommend you postpone any air travel.
• Travel with a companion to ensure your safety in the event of an emergency.
• Talk to your doctor about whether vaccinations recommended for different areas can be administered when you are pregnant. Together, you can weigh up the risks and benefits of medications and immunisations.
• Most airlines will not allow travel by women beyond the 36th week of pregnancy. You may need to carry a letter from your doctor stating your due date. The Civil Aviation Safety Authority in Australia advises that pregnant women who are expecting multiple births or experiencing complications throughout their pregnancy may be required to seek medical approval for both international and domestic air travel.
• Avoid less developed areas where emergency medical treatment and supplies may not be readily available.
• If you are flying or driving, wear you seatbelt low around your pelvis, and stretch your legs as much as you can.
• Avoid water sports while you are pregnant: water skiing and scuba diving could harm your baby.
• Avoid hot tubs and saunas as excessive heat may place your baby at risk.
• If you are close to term, check the availability of medical facilities at your destination.
• Pregnant women have an increased susceptibility to malaria, and contracting the disease may increase the likelihood of a premature birth. If you are travelling to a malarial area discuss the use of antimalarial medications with your doctor; avoid the outdoors between dusk and dawn and use sprays and mosquito coils.
• Remember that newborns less than 6 weeks old should not fly, as they are not developed enough to cope with discomfort caused by atmospheric changes within the aircraft.
• Always consult your doctor or healthcare professional prior to planning your travel and holiday activities.
