DIABETIC KETOACIDOSIS Diabetic ketoacidosis is a problem that occurs in people with diabetes. It occurs when the body cannot use sugar (glucose) as a fuel source because there is no insulin or not enough insulin. Fat is used for fuel instead. Byproducts of fat breakdown, called ketones, build up in the body. Causes People with type 1 diabetes do not have enough insulin, a hormone the body uses to break down sugar (glucose) in the blood for energy. When glucose is not available, fat is broken down instead. As fats are broken down, acids called ketones build up in the blood and urine. In high levels, ketones are poisonous. This condition is known as ketoacidosis. Blood glucose levels rise (usually higher than 300 mg/dL) because the liver makes glucose to try to combat the problem. However, the cells cannot pull in that glucose without insulin. Diabetic ketoacidosis is often the first sign of type 1 diabetes in people who do not yet have other symptoms. It can also occur in someone who has already been diagnosed with type 1 diabetes. Infection, injury, a serious illness, missing doses of insulin, or surgery can lead to diabetic ketoacidosis in people with type 1 diabetes. People with type 2 diabetes can also develop ketoacidosis, but it is rare. It is usually triggered by a severe illness. Hispanic and African-American people are more likely to have ketoacidosis as a complication of type 2 diabetes.
