What are ketones?
Ketones are byproducts of fat breakdown which can occur when the body cannot use sugar to make energy. It often occurs when there is not enough insulin in the body or when a patient is sick or dehydrated. A large amount of ketones in the body can cause stomachache, vomiting, or lead to ketoacidosis. A large amount of ketones also causes a sweet odor to the breath. Ketones can be detected in blood or urine.
