What Are Ketones and Why Should I Test for Them?
Ketones are the waste products produced when your body breaks down fatty acids for energy. Toxic ketone levels can build up and spill into urine. This is a sign that your diabetes is not well controlled—perhaps because of tiredness and fatigue—and you will feel increasingly unwell. If left untreated, ketone build-up can lead to coma and even be life threatening. Contact your healthcare professional if you detect a build-up of ketones in your urine.
