Is It Safe to Travel While Pregnant?

Travelling has now become an integral part of our lives – whether it’s for work, family or a baby-moon, long and short distance air travel has become more accessible and common among pregnant women. 

Although very safe, there are some pregnancy and travel-related concerns that you should be aware of. With this in mind, we’ve compiled some information to help make your travels safer and more comfortable. 

Should You Travel When Pregnant?

As long as there are no concerns about your pregnancy, you’re generally safe to travel at all times during your pregnancy. Always check with your doctor beforehand, though! 

The second trimester is probably the best time to travel while pregnant. This is when morning sickness should settle down, and the belly is not yet big enough to cause major discomfort. Usually, changes in air cabin pressure and in-flight turbulence can increase the risk of discomfort. If you have any concerns, you can also check individual airlines' travel restrictions for pregnant women in advance. 

What Are the Risks of Travelling When Pregnant? 

Generally, when flying on long-haul flights or sitting for prolonged periods, there’s a risk of pregnant women developing deep vein thrombosis (DVT, 深部靜脈血栓). 

What is Deep Vein Thrombosis? 

DVT (深部靜脈血栓) is when a blood clot forms in the vein. It’s more common for a clot to develop in the calves, but it can also happen in the lungs (which is rare, but fatal when it does occur). DVT can occur in the non-pregnant population, but pregnancy increases the risk of occurrence. 

How to Prevent DVT?

By addressing the risk factors for DVT, it can be prevented. Here are some steps you can take when travelling:

• Wear compression stockings on flights and when prolonged immobilisation is anticipated
• Keep well hydrated with water
• Avoid alcohol and caffeinated drinks
• Stay mobile on planes (stretch exercises every 30 minutes to keep blood flowing)
• Choose an aisle seat if possible when travelling on flights 

Some women at high risk of DVT may also need heparin prophylaxis for their flights, which is a medication used to prevent and lower the chances of DVT from occurring.

When Should You Avoid Travelling While Pregnant?

In some certain pregnancy conditions, commercial air travel and overseas holidays may be unsafe, and travelling should be avoided if possible. Here are some examples of scenarios where you should avoid travel: 

• Severe anaemia
• Recent vaginal bleeding
• Severe maternal heart or lung disease 
• Recent otitis media (middle ear infection) or sinusitis 
• Recent abdominal surgery 
• Recent fracture still in a cast

The above list is not exhaustive – please discuss with your doctor if you have concerns or if you’re planning to travel while pregnant. 

Other Travel Tips & Advice

When travelling to tropical areas, pregnant women should bring insect repellants to avoid certain insect-borne infections (such as dengue fever or the Zika virus). There are also other safety precautions you can take, such as:

• Wear light-coloured, long-sleeved clothing
• Avoid being outdoors at dawn and dusk
• Apply insect repellent to exposed body parts and clothing only
• Wash skin when returning indoors and clothing sprayed with insect repellent
• Sleep in beds with mosquito nets if air conditioning is not available
• When applying sunblock, do so before using insect repellent

Insect repellents that are safe to use in pregnancy and breastfeeding include: 

• DEET (less than 50% concentration)
• Picaridin
• Oil of lemon eucalyptus or para-menthane-diol
• IR3535

Additionally, pregnant women should avoid travellers’ diarrhoea by only consuming thoroughly cooked food and drinking pre-packaged chilled drinks (as opposed to ice drinks).
