Generally, flying is safe for pregnant women before 36 weeks of gestation, provided there are no pregnancy complications. However, it’s always best to consult your healthcare provider before planning any air travel during pregnancy.
Your doctor might advise against flying if you have certain pre-existing conditions or pregnancy-related issues that could be exacerbated by air travel or require urgent medical attention. These conditions may include a history of miscarriage, vaginal bleeding, severe anemia, or poorly controlled high blood pressure or diabetes. If you experienced preeclampsia in a previous pregnancy, or if you are pregnant with twins or multiples, flying might also be discouraged.
It’s important to inform your healthcare provider about the duration of your flight, as longer flights may pose different considerations. Additionally, be aware that some airlines have specific restrictions on pregnant passengers, particularly for international flights. Always check with your airline regarding their policies for pregnant travelers before making any bookings.
After 36 weeks of pregnancy, many healthcare providers recommend against air travel. Furthermore, numerous airlines restrict pregnant women from flying after this point. Airlines may also request a letter from your healthcare provider confirming your due date and stating that air travel is safe for you.
If your healthcare provider approves air travel, and your schedule permits flexibility, the second trimester is often considered the most optimal time to fly. During this period, the likelihood of common pregnancy emergencies is at its lowest.
When you do fly while pregnant, keep these tips in mind for a safe and comfortable journey:
- Fasten Your Seatbelt: Always keep your seatbelt securely fastened whenever you are seated. Position the belt comfortably below your baby bump.
- Stay Hydrated: The cabin air in airplanes has low humidity, which can easily lead to dehydration. Drink plenty of water throughout your flight.
- Choose Your Foods Wisely: Avoid foods and drinks that can cause gas before and during your flight. Gas expands at higher altitudes and can cause discomfort. Common culprits include broccoli and carbonated beverages.
- Plan for Medical Needs: Think about how you would access obstetric care at your destination if needed. Carry copies of your important medical records in case of any medical situations while traveling.
Understanding Blood Clot Risks During Air Travel in Pregnancy
Air travel can slightly increase the risk of developing blood clots in the legs, known as venous thrombosis. This risk is naturally elevated during pregnancy. To mitigate this, regular movement is key. Make it a point to walk up and down the aisle every hour during your flight. If you are unable to move around, perform ankle flexes and extensions frequently while seated. It’s also advisable to wear loose-fitting clothing to promote healthy blood circulation and consider using compression stockings, especially on longer flights, to further aid circulation.
Concerns About Radiation Exposure from Air Travel During Pregnancy
Exposure to radiation during air travel at high altitudes is generally considered minimal and not a significant concern for most pregnant individuals. However, for those who fly frequently, such as pilots and flight attendants, the cumulative radiation exposure could potentially be a concern during pregnancy. If your job requires frequent flying while pregnant, it’s important to discuss this with your healthcare provider to assess any potential risks and take necessary precautions.
