Diabetes is a disease in which your blood sugar (glucose) levels are too high.
Diabetic ketoacidosis is a serious complication of diabetes. It's often called DKA.
With DKA, your blood sugar goes up, acids called ketones build up in your blood, you lose a lot of fluid, and your body chemistry doesn't work right. You need treatment right away.
Your body needs insulin to use blood sugar for energy. If you don't have enough insulin (for example, because you have untreated type 1 diabetes), your blood sugar goes up a lot because the sugar can't get into your cells. Your body burns fat for energy instead. Broken-down fat goes to your liver and is turned into acids called ketones. The ketones build up in your blood and urine.
A high level of ketones in your blood can make you very sick.
