9. Sick Days

For your tamaiti / child, rangatahi / young person with diabetes

Understanding illness and diabetes

  • Tamariki (children) and rangatahi (young people) with diabetes do not usually get sick more often than others. However, when they are unwell, diabetes can be harder to manage.

  • When your tamaiti (child) is sick, the body releases stress hormones. These hormones can affect blood glucose levels:
    • Illness with fever or infection often causes high glucose levels
    • Gastro illness (vomiting and diarrhoea) can cause low glucose levels
    • Vomiting may also be a sign that there is not enough insulin in the body

  • Because of this, your tamaiti (child) needs closer monitoring and ongoing insulin when sick.


General principles

If your tamaiti / child is unwell:

  • Always give insulin – never stop insulin completely

  • Contact your diabetes team for advice about dose changes

  • Take your tamaiti (child) to your GP to treat the illness

  • Check blood glucose levels every 2 hours
    • Use finger prick testing – CGMS sensor may not be accurate if your child is dehydrated.

  • Check blood ketones every 2 hours

  • Encourage your tamaiti to drink plenty of fluids


Managing symptoms

  • Treat pain or fever with Paracetamol or Ibuprofen

  • Even if your rangatahi (young person/adolescent) usually manages their diabetes independently, they will need extra support from their whānau (family) when unwell


Sick Day Insulin Adjustments – Injections

Ongoing high levels (above 10 mmol/L, including overnight)

  • If repeated corrections are not enough:
    • Increase the long-acting insulin (Lantus) dose by 20%

How to calculate 20%

  • Multiply usual dose × 0.20

Example:

  • Usual Lantus = 20 units

  • 20 × 0.20 = 4 units

  • New dose = 24 units

Return to the usual Lantus dose once your tamaiti (child) is well again.


Sick day Insulin adjustments on Insulin Pump Therapy

General approach

  • Follow all the general sick day advice above (monitoring, fluids, ketones, etc.)


Sickness on a pump

Being unwell usually makes you have high glucose. If your glucose has been higher than normal for more than 3 hrs then consider:

  • Use a plus 30% or 50% profile (or “boost” for YpsoPump).

  • Check your glucose before meals and snacks as usual or at your usual mealtimes if you are not eating. You may still need a correction even if you are not eating.

  • Check for ketones if your glucose is >15 mmol/L.

  • If ketones >1.0 and not resolving, follow the protocol for high glucose levels

If you are vomiting, you are more likely to have low glucose.

  • Check for ketones, even if glucose is normal, as you can develop ketones from starvation. If Ketones are >1, call the medical team or visit CED.

  • If glucose is <10mmol/L and not eating, encourage small amounts of sugary drinks e.g., diluted juice

  • Consider using a minus 30% or 50% profile (or “ease off” for YpsoPump) if having many lows.


When to call for help

Contact your diabetes team if:

  • Ketones are ≥1.0 mmol/L and not improving despite the plan above

  • Blood glucose remains:
    • below 4 mmol/L, or
    • above 10 mmol/L despite treatment

  • Your tamaiti (child) has ongoing vomiting or tummy pain

  • You are worried or unsure how to manage things or change insulin doses yourself

  • Your tamaiti (child) is very drowsy, confused, or breathing heavily (call 111 for ambulance)


Information to have ready

When you call, be ready to tell the team:

  • Age of your tamaiti / child

  • Symptoms (e.g., fever, vomiting)

  • Blood glucose and ketone levels

  • Whether your tamaiti (child) is eating or drinking

  • Usual insulin doses

  • Any medications given


Ketones explained

  • There is not enough insulin (missed insulin or pump site failure)

  • Your tamaiti (child) is unwell

  • Your tamaiti (child)is not eating – called starvation ketones

Ketones can occur:

  • During illness

  • When glucose levels are high

  • Even when glucose levels are normal or low (especially with vomiting)

If not treated, ketones can build up and make your tamaiti (child) very unwell.


Ketoacidosis (DKA) – Serious emergency

High ketones can cause the blood to become acidic. This is called diabetic ketoacidosis (DKA).

Symptoms include:

  • Nausea and vomiting

  • Tummy pain

  • Heavy or fast breathing

  • Fruity-smelling breath (like nail polish remover)

  • Confusion or drowsiness

  • Unconsciousness

If your tamaiti (child) has these symptoms, go immediately to: Starship Children's Hospital Emergency Department or your nearest Emergency Department.


When to test ketones

  • Every 2 hours during illness using CareSens Dual meter

  • If your tamaiti (child) is well but glucose is 15 mmol/L or higher twice in a row

Mini-dose glucagon

Mini-dose glucagon may be advised by your doctor when:

  • Blood glucose remains below 4 mmol/L despite treatment

  • Your tamaiti (child) has gastro illness

  • Your tamaiti (child) cannot or will not eat

This involves giving a small dose using an Insulin syringe (not the syringe that comes with the kit)

If you want to learn more about use of mini dose glucagon: Mini-dose glucagon

  • Only use this if directed by a doctor. Some tamariki (children/young people) may need hospital admission if glucose cannot be maintained.


Sick Day Kit (for your whānau / family)

Prepare a kit at home and check every 6 months:

  • Diabetes team contact details

  • Insulin pens and insulin.

  • Spare correction chart.

  • Pump supplies with details of correct correction factor documented (if used)

  • Blood glucose meter and strips

  • Blood ketone meter and strips

  • Fluids (sweet and sugar-free options)

  • Easy foods (soups, ice blocks)

  • Glucagon kit and insulin syringes ( for mini-dose gluagon)

  • Pain relief (Paracetamol or Ibuprofen)

  • Thermometer

  • Optional: medication for nausea or diarrhoea when travelling


Surgery and procedures

If your tamaiti (child) needs surgery or is fasting:

  • Insulin must still be given

  • The diabetes team must be involved in planning as doses will need to be changed

  • Morning procedures are preferred

  • Ideally performed at hospital experienced in dealing with tamaiti (child) with diabetes such as Starship Child Health


Other medications

Some medications (especially steroids) can raise blood glucose levels.

If your GP or hospital prescribes medication:

  • Ask if it will affect glucose levels

  • Contact your diabetes team for advice on insulin adjustments
