Is it dangerous for me to vacation at high altitude during pregnancy?

What height?: Absolute numbers are uncertain as studies are small. It is actually the altitude a pregnant woman sleeps at which may be most important--certainly below 10, 000 feet, ; some say 8, 000 feet--may be safest for visiting pregnant tourists. Slow ascents are best. If the pregnancy has any complications or concerns at sea level, altitude plans should be discussed first with health provider.

Ask your OB: If you are not from a high altitude place it would be better not to vaca at a high altitude place.
