Diabetes and illness during travel
Control of diabetes if you fall ill during your travel.

  • In addition to the vaccinations usually recommended for your travel, diabetics should consider vaccination against influenza and pneumonia (Pneumococci bacteria).

    Vomiting and diarrhoea
  • You loose fluid and rapidly become dehydrated.
  • Always keep a bottle with clean water and drink regularly.
  • If you have been vomiting you may need extra calories.
  • Tea with sugar provide calories and fluid.
  • If you have diarrhoea and have been vomiting you need to control your blood sugar more often, for instance every second hour.
  • If you have been vomiting for more than six hours with or without diarrhoea you should visit a doctor.

  • The blood sugar increase during febrile episodes and so do the need for insulin no matter how much you eat.
  • The need for insulin may increase with between 25% and 50% during fever.
  • Fever increase the risk of acidosis.
  • When having fever, it is necessary to measure the blood sugar more often, increase the insulin dose and control the urine for ketones.
