Generally, for expectant mothers without complications, air travel is considered safe up to 36 weeks of pregnancy. However, it’s always wise to consult with your healthcare provider before planning a flight during pregnancy.
Your doctor might advise against air travel if you have certain pregnancy-related conditions that could be exacerbated by flying or require urgent medical attention. These conditions may include a history of miscarriage or vaginal bleeding, severe anemia, or poorly managed high blood pressure or diabetes. If you experienced preeclampsia in a previous pregnancy, a condition marked by high blood pressure and protein in the urine, flying might also be discouraged. The same caution applies if you are pregnant with twins or other multiples.
It’s important to inform your healthcare provider about the duration of your flight, as longer flights may pose different considerations. Furthermore, be aware that some airlines have restrictions on pregnant passengers, particularly for international flights. Always check with your specific airline regarding their policies before making any travel arrangements.
After the 36th week of pregnancy, most healthcare providers recommend against flying. Many airlines also restrict air travel for pregnant women beyond 36 weeks. Airlines may require a letter from your healthcare provider confirming your due date and stating that air travel is safe for you.
If your healthcare provider gives you the green light to fly and your schedule is flexible, the second trimester is often considered the most optimal time for air travel during pregnancy. This period typically has the lowest risk of common pregnancy emergencies.
Essential Tips for Flying While Pregnant
When you do fly, consider these helpful tips for a safer and more comfortable journey:
Buckle Up Safely
Always keep your seatbelt securely fastened whenever you are seated. Position the seatbelt low and snug across your hips, beneath your baby bump, to ensure safety and comfort.
Stay Hydrated Throughout Your Journey
The low humidity levels in airplane cabins can easily lead to dehydration. Drink plenty of water and juices before, during, and after your flight to stay well-hydrated. Avoid excessive caffeine and sugary drinks, as these can contribute to dehydration.
Choose Your Foods and Drinks Wisely
Before your flight, it’s advisable to avoid foods and beverages that are known to cause gas. Gas expands at higher altitudes, which can lead to discomfort during your flight. Foods like broccoli, beans, and carbonated drinks should be limited or avoided before flying.
Plan Ahead for Medical Care
Before you travel, think about how you would access obstetric care at your destination should you need it. Carry copies of your essential medical records, including your prenatal records, just in case you require medical attention while you are away from home.
Understanding Potential Risks: Blood Clots and Radiation
While generally safe, air travel does present some minor risks that are worth considering, especially during pregnancy.
Blood Clots (Venous Thrombosis)
Air travel, particularly on long flights, can slightly increase the risk of developing blood clots in the legs, a condition known as venous thrombosis. This risk is naturally elevated during pregnancy. To minimize this risk, regular movement is key. Make it a point to walk up and down the airplane aisle every hour. If you are required to remain seated, perform ankle flexion and extension exercises frequently to promote blood circulation in your legs. Wearing loose-fitting clothing can also help improve blood flow. Compression stockings are highly recommended for pregnant women during longer flights to further assist with blood circulation.
Radiation Exposure During Flights
Exposure to cosmic radiation is higher at the altitudes at which airplanes fly. For most people who occasionally fly during pregnancy, the level of radiation exposure is not considered a significant concern. However, for individuals who are frequent flyers, such as pilots and flight attendants, the cumulative radiation exposure could potentially be a concern during pregnancy. If your job requires frequent flying during pregnancy, it is prudent to discuss this with your healthcare provider to assess any potential risks and take necessary precautions.
Conclusion
In conclusion, flying during pregnancy is generally safe for women with uncomplicated pregnancies, particularly before 36 weeks. Always prioritize a consultation with your healthcare provider before you fly to discuss your individual circumstances and any potential risks. By following recommended precautions and being mindful of your body’s needs, you can ensure a safer and more comfortable air travel experience during your pregnancy.
