Typical situations

High blood sugar

High blood sugar (over 10 mmol/l) is not an emergency, but it does need action. Over 13.9 mmol/l is notably high, and then it is worth checking ketones too.

What counts as high

Over 10 mmol/l is high. Over 13.9 mmol/l is notably high. Untreated or during a serious infection, the value can rise as far as 20–30 mmol/l.

What the child feels

  • Heavy thirst and frequent urination (above 10 mmol/l, sugar starts leaking into urine)
  • Tiredness, dry mouth, blurred vision, nausea
  • If it lasts, level of consciousness and reaction speed drop

Most common causes

  • Meal insulin was too small or forgotten
  • Carbs were estimated too low
  • An infection coming on or ongoing
  • Stress or nerves (e.g. an exam, a performance)
  • Less exercise than usual
  • Cortisone medication
  • The menstrual cycle
  • The pump cannula is leaking, blocked or has come loose

What to do

Correct a high blood sugar according to the parents' written instructions, usually together with a meal. With a pump, use the dose calculator. Measure more often until the value settles.

The exact correction dose is not in general sources

The correction dose is always specific to the child. Ask your clinic for written, personal instructions (correction factor and sick-day rules) and keep them within reach.

Over 15 mmol/l → measure ketones

If the child is unwell and blood sugar is over 15 mmol/l, measure ketones from blood.
