In some cases, the total lack of insulin leads to a condition called diabetic ketoacidosis. When you do not have enough insulin, blood glucose levels rise. Yet, that glucose cannot enter the body’s cells to generate energy. In response, the body starts breaking down stored fat for energy. The by-products of fat breakdown are called ketone bodies. These ketone bodies are composed of acids that build up in the blood and cause diabetic ketoacidosis.
