If you have a serious medical situation, it doesn't mean you can't fly. But the stress of travel can take its toll, so here's what you need to know.

If you have a pre-existing condition, or even think you might have one, talk to your physician before traveling.

In some cases, you may need to get a medical certificate clearing you to fly within 10 days of departure.

Airlines are within their rights to require a certificate for passengers who require medical oxygen during a flight, have an infectious disease, or-here's a loophole you can drive a Hummer through-when there's "reasonable doubt" that the passenger can fly without requiring medical assistance.

Pregnant women flying within four weeks of their due date-which we don't recommend anyway-are also, required having a medical certificate.

Conditions like anemia, circulatory issues, or heart or lung problems can be affected by low oxygen and humidity in the cabin.

Also, remember long-distance travel and jetlag can interfere with the timing of taking medication.

The bottom line is that you can protect yourself with a little advance planning: check in with your doctor, carry on backup medications, insulin, or other emergency supplies, and keep a copy of your physician's business card, as well as a medical ID card or bracelet identifying your condition.
