Are cruises safe during pregnancy?

What does the evidence say about cruises during pregnancy?

1. Most cruise lines restrict travel beyond 24 weeks' gestation and may require a physician's note confirming the pregnancy is not high-risk, including the estimated due date. 1
2. Travel medicine guidance flags the possibility of delayed care while at sea, along with gastrointestinal and respiratory infections, motion sickness, and falls on a moving vessel, as the main health considerations for pregnant cruise passengers. 1
3. A personal history of motion sickness is a known risk factor for nausea and vomiting of pregnancy, possibly due to a shared vestibular mechanism, which can make seasickness and pregnancy nausea compound each other on a cruise. 2
4. Prolonged immobility and dehydration during travel are linked to a 2 to 4 fold higher risk of venous thromboembolism compared with not traveling, so getting up to walk around periodically and staying hydrated on a multi-day cruise is a reasonable precaution. 3
5. Small frequent meals with a protein source, staying well hydrated, and keeping solids and liquids separate is the same first-line approach MotherToBaby recommends for pregnancy nausea generally, and it can help with seasickness on board too. 4

Is cruises safe in each trimester?

• First trimester. Cruises early in pregnancy carry the fewest cruise-line restrictions, but motion sickness can compound normal first-trimester nausea, since a personal history of motion sickness is a known risk factor for nausea and vomiting of pregnancy and the two may share a vestibular mechanism.
• Second trimester. This is generally the window most cruise lines allow, though the fitness-to-travel documentation requirement still applies. Delayed access to full obstetric care at sea remains the core planning consideration regardless of trimester.
• Third trimester. Most cruise lines restrict travel beyond 24 weeks' gestation, so a third-trimester cruise often isn't bookable at all. Confirm your specific line's cutoff before planning one.
