Extremely high levels of blood sugar that remain untreated for a long time may lead to diabetic ketoacidosis (DKA). In diabetic ketoacidosis, your blood sugar levels shoot up really high and lead to the build-up of ketones in your body. This serious medical condition can lead to diabetic coma or even death. Some of the warning signs of DKA include:
1.Shortness of breath
3.Nausea and vomiting
4.A very dry mouth
Remember, DKA should be treated as a medical emergency and you should consult a doctor as soon as possible.
