Diabetic ketoacidosis (DKA) occurs when a person’s blood sugar (glucose) is too high because there is not enough insulin. Instead, the body starts to burn fat for energy. Fat is broken down into acids, causing acid levels to build up in the blood. These acids appear in urine and blood as ketones. DKA is a serious condition that can lead to coma or death if not treated.

This situation is most often caused by uncontrolled type 1 diabetes and sometimes type 2 diabetes.
