Is it safe to fly during pregnancy with a low-lying placenta?

Question

Hello doctor,

I was diagnosed with a low-lying placenta at my 12-week NT scan. However, the internal OS is not covered. My doctor mentioned that as the uterus expands, the placenta might move upward. I need to take a 5.5-hour flight. When would be the safest time for me to travel?

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Since you have been diagnosed with a low-lying placenta at 12 weeks, your doctor is correct that, in most cases, the placenta moves upward as the uterus expands. However, traveling, especially a 5.5-hour flight, requires careful consideration.

Is it safe to travel?

Best time to travel: The second trimester, which is from 14 to 28 weeks of pregnancy, is generally considered the safest time for travel. During this period, symptoms such as nausea and fatigue tend to decrease, and the risk of complications is lower.
Placenta position: Since your placenta is not covering the cervix (internal os), and your doctor expects it to move upward, traveling might be possible if no new complications arise.
Flight considerations: Long flights can increase the risk of developing blood clots, also known as deep vein thrombosis. Therefore, it is essential to take specific precautions to reduce these risks.

Precautions before traveling:

Consult your doctor again before booking: A follow-up ultrasound before travel, ideally between 16 and 20 weeks of pregnancy, can help determine if the placenta has shifted upward. If it remains low, your doctor might advise against traveling.
Stay hydrated and move around: Drink plenty of water and make it a point to walk every hour during the flight to reduce the risk of blood clots. You might also consider wearing compression stockings to improve blood circulation.
Avoid heavy lifting and strenuous activity: Since a low-lying placenta can increase the risk of bleeding, it is advisable to avoid carrying heavy luggage or engaging in strenuous activities.
Choose an aisle seat: This makes it easier for you to move around and access the restroom frequently, which is essential for circulation and comfort.
Know emergency contact details: Before traveling, find out about hospitals and healthcare facilities near your destination in case of any emergency.

When to avoid travel:

If you experience bleeding, cramping, or any complications before your trip, it is best to avoid traveling.
If your next scan shows that the placenta remains low and close to the cervix (raising the risk of placenta previa, where the placenta covers the cervix).
If your doctor advises against it due to other risk factors or complications.

Since your placenta is not covering the cervix, you may be able to travel during the second trimester if there are no additional risks. However, it is best to wait for your next scan to confirm the placenta's position before finalizing your travel plans. Consulting with your doctor before flying is crucial to get personalized advice based on your specific situation.
