If you're hitting the road, air, or sea with diabetes, you'll need to take some special precautions to ensure your trip is both safe and enjoyable.

Don't stress. Stress can cause blood sugar levels to rise, so remember the R & R component of vacationing and don't overplan.

BYOS. Bring your own snacks, even if you anticipate eating in flight or stopping for a meal. You never know when delays could send blood sugar plummeting.

Double up. Bring twice as much medication, insulin, and supplies as you think you'll need, particularly if you're traveling abroad.

Carry on. Always carry your medical supplies on board with you rather than checking them in luggage.

Get a doctor's note. If you're flying with medical sharps (i.e., lancets, syringes) or a pump, it's a good idea to have both the original prescription labels for the insulin and a note from your doctor explaining your medical need.

Stay cool. If you're traveling in hot climates, get a cooling or insulated bag for insulin and keep supplies out of direct sunlight.
