ketosis





An elevated level of ketone bodies (β-hydroxybutyrate and acetoacetate) in the body tissues. Ketone bodies are normal products of fat metabolism and can be oxidized to produce energy. Abnormally high levels arise when there is an imbalance in fat metabolism, such as occurs in diabetes mellitus or starvation. Ketosis may result in severe acidosis. See also ketonuria.
