Diabetic ketoacidosis is caused by lack of insulin, and is generally triggered by some other body insult including dehydration, fasting, illness or infection.
Once ketoacidosis begins in earnest, it causes itself to get worse. All of its symptoms are also causes of further problems, so it will generally continue to advance until treatment or death.
More details on the mechanism of how ketoacidosis begins are available on the wikipedia link below.
Ketoacidosis is often associated with hyperglycemia (high blood sugar), but hyperglycemia won't actually cause Ketoacidosis. They are both caused by shortage of insulin.
If hyperglycemia is left untreated, it can lead to ketoacidosis.
Diabetes
One of the first signs of ketoacidosis is an unpleasant smell on the breath as well as ketones in the urine, if your insulin is kept at the correct level and you eat a sensible and balanced diet including slow release carbohydrates you should not go into ketoacidosis.
The normal blood pH is typically between 7.35 and 7.45. In ketoacidosis, blood pH is usually lower than 7.35, indicating acidosis.
When you have to be hospitalized for diabetes you are in ketoacidosis, which is when your blood sugar is very high. If you are in really bad ketoacidosis then you may be in a coma.
Diabetic ketoacidosis is a condition which is thought to affect about 1 in 750 people in their lifetime. More information can be obtained from reputable medical journals or a doctor.
Diabetes, if untreated.
Ketone production in diabetes causes a condition called diabetic ketoacidosis, which is a form of elevated anion gap metabolic acidosis.

FALSE
Urea levels can be elevated in ketoacidosis due to increased breakdown of protein as the body tries to generate more glucose for energy production. This results in higher levels of nitrogen-containing waste products like urea in the blood. Additionally, dehydration and impaired kidney function in ketoacidosis can also contribute to increased urea levels.
