When is high, too high?
A build-up of ketones changes the delicate pH balance in your blood. This can cause a condition called diabetic ketoacidosis (DKA), which can be life-threatening. DKA can result in:
- Loss of consciousness
- Diabetic coma
- Swelling of the brain
- Death
This is why prompt treatment of high ketones is so important!
When should I test for ketones?
You should test your urine or blood for ketones in any of the following situations:
- Your blood sugar is higher than 15 mmol/L
- You are experiencing frequent urination, extreme thirst, nausea, vomiting, confusion, or fruity-smelling breath
- You are sick and are unable to eat or drink for a prolonged period of time
How do I test for ketones?
You can test your blood or urine to measure ketone levels.
Urine ketone strips can be bought without a prescription at a pharmacy. They turn a dark colour after 15 seconds when dipped in urine. The amount of ketones is indicated by how dark the strip turns.
Meters are also available to test your blood for ketones. These meters have strips that are very similar to blood glucose testing strips, which indicate the level of ketones.
