If you have diabetes, traveling requires extra planning. Changes in meal patterns, activity levels, and time zones can affect your blood sugar levels. A little extra effort in advance can make your trip go smoother.

Before Your Trip

  • Tell your doctor about your plans. Ask for a letter explaining that you have diabetes and some extra prescriptions. Carry this with you at all times during your travel.
  • Ask your doctor about adjusting insulin doses if you're crossing time zones.
  • Get twice as many supplies as you think you'll need. If you need immunizations, plan to get them 3 to 4 weeks before your vacation. Be aware that some shots can affect your blood sugar levels. Talk to your doctor first.
  • Be prepared. Scope out health care centers where you're going.
  • Talk to the airline, hotel, or cruise ship about special meals.
  • Learn certain phrases in the local language such as "I need help" or "I have diabetes," "Where is the hospital," and "I need sugar."

What Should You Take?

  • A piece of paper or card with your doctor's name and phone number. Keep it with you at all times.
  • A list of current medicines. Keep it with you at all times.
  • Medical identification that says you have diabetes.
  • Medicines, syringes, inhaler and cartridges, blood sugar testing supplies, and all oral medications. Keep them in your carry-on luggage. Don't risk a checked bag getting lost or sitting in an unheated, uncooled cargo hold.
  • Enough medicines and medical supplies to last an extra week.
  • A traveling companion to carry some of your medical supplies, if possible.
  • Some type of sugar source in case you develop low blood sugar.

Getting Through the Airport

Tell security that you have diabetes and have medical supplies with you. You can take them through security checkpoints, but they must have a prescription label and a proper manufacturer's label.

Syringes will be allowed through security if you have insulin, too.

Notify security if you're wearing an insulin pump. They will inspect the meter -- you must ask them not to remove it.
