Lexique du diabète


Ketones form in your body when your body starts using fat instead of carbohydrates to create energy. When the body does not have enough insulin to move glucose (sugar) from the blood to the cells, the body uses fat to create energy. When fat is broken down, ketones are formed and can then accumulate in the body. High ketone levels (ketones in the blood) are toxic to your body. The accumulation of ketones in the blood is called ketoacidosis.⁴
