Few things are more frightening than suffering a medical problem while you are away from home. Fortunately, good planning can prevent most health mishaps.

When overseas travelers become ill, its usually because of an infection or disease that is contracted in a foreign country. But both international and domestic travelers are vulnerable to unexpected complications arising from pre-existing medical conditions.

Not everyone planning to board an airplane needs to visit his/her doctor. However, it may be important if you have a current medical problem. Check with your doctor before flying if you have

Anemia - If your hemoglobin level (measurement of a protein in red blood cells) is less than 8.5 grams per 100 milliliters, you may need supplemental oxygen during the flight because of the cabins reduced oxygen level. You must arrange this with the airline at least 48 hours in advance.

Heart disease - If you suffer from unstable angina, serious arrhythmias or congestive heart failure, you may not be fit to fly. If you have had a heart attack, wait at least two weeks before flying. All heart disease patients should consult their doctors before flying.

If you have recently had abdominal surgery, such as laparoscopic gall bladder removal, you should avoid flying for a few weeks. Any air that might have been introduced into your abdominal cavity during surgery will expand at higher altitudes, where cabin pressure is lower.

By the same token, a recently applied cast, which contains air bubbles, may become dangerously tight during flight as those bubbles expand and impede blood circulation to that area. Wait at least 48 hours after being fitted with a cast before flying.

Important: Pack all of your medical supplies in carry-on baggage, rather than in checked luggage. Many medications and batteries can freeze in the baggage compartments.

If you are carrying syringes, make sure you have a signed, stamped note from your doctor explaining why you need the syringes.

If you have a chronic disease, such as diabetes, emphysema or cancer, consider bringing a copy of your pertinent medical records. If you have heart disease, bring a copy of your latest electrocardiogram.

Certain travel destinations can also cause medical problems. A high-altitude location, whether it is a Colorado ski resort, Nepal or Peru-may be dangerous for those patients with heart or lung disease. The air is thinner at high altitudes, which means there is less oxygen available to breathe.

Asthmatics should check with their doctors before visiting heavily polluted cities, such as Bangkok, Beijing and Mumbai.

Even healthy people are at increased risk for illness while traveling. Nearly 30% of those visiting Mexico, the Caribbean and other popular tropical destinations experience travelers diarrhea, even when staying at top resorts.

Self-defense:Avoid local water (including ice cubes) as well as uncooked or under-cooked food. Bring loperamide (Imodium), which will help decrease your symptoms if you do become ill.
