per- or hypoglycaemic episodes, are generally at low risk for travel. It’s
the insulin-dependent individuals who need to take care. “It’s important
to take a sufficient supply of insulin and injectable materials, as well as
extra testing strips and extra batteries for the glucometer. Patients should
also carry extra snacks in their bags, so that these are handy in the event
of a hypoglycaemic episode. Airline staff should be informed of an indi-
vidual’s diabetic status, so that they are prepared and can take action in
the event of an emergency.”
Crossing time zones has implications for insulin requirements, which
may need to be adjusted accordingly. “Eastbound flights, which usually
take place overnight, are likely to require reduced insulin intake, so as to
avert a possible hypoglycaemic episode while asleep. Westbound flights
tend to take place during the day, encouraging travellers to eat more than
usual. As a result, it may be necessary to increase insulin dosages.” The
Aerospace Medical Association provides good guidelines for insulin dose
adjustment for travellers.
Diabetes in itself is a risk for DVT, and this is aggravated by the fact
that many patients are overweight.
Insulin can destabilise at extreme temperatures, both hot and cold.
While travelling, patients need to ensure that they keep their insulin at
the correct temperatures as specified by the manufacturer. Diabetics are
likely to experience more heat-related issues than healthy travellers, and
are more predisposed to symptoms such as headache and dizziness in
hot climates. Adequate foot care is also essential, if they’re going to be
walking more than usual.
