Ketosis is a metabolic state characterized by elevated levels of ketone bodies in the blood or urine. Physiological ketosis is a normal response to low glucose availability. In physiological ketosis, ketones in the blood are elevated above baseline levels, but the body's acid–base homeostasis is maintained.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Diabetic ketoacidosis may be diagnosed when the combination of hyperglycemia (high blood sugars), ketones in the blood or on urinalysis and acidosis are demonstrated. [6] In about 10% of cases the blood sugar is not significantly elevated ("euglycemic diabetic ketoacidosis"). [3] A pH measurement is performed to detect acidosis.
Both acetoacetate and beta-hydroxybutyrate are acidic, and, if levels of these ketone bodies are too high, the pH of the blood drops, resulting in ketoacidosis. Ketoacidosis is known to occur in untreated type I diabetes (see diabetic ketoacidosis ) and in alcoholics after prolonged binge-drinking without intake of sufficient carbohydrates (see ...
Ketotic hypoglycemia refers to any circumstance in which low blood glucose is accompanied by ketosis, the presence of ketone bodies (such as beta-hydroxybutyrate) in the blood or urine. This state can be either physiologic or pathologic; physiologic ketotic hypoglycemia is a common cause of hypoglycemia in children, often in response to ...
An elevated level of ketone bodies in the blood (a state called ketosis) eventually lowers the frequency of epileptic seizures. [1] Around half of children and young people with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists after discontinuing the diet. [ 2 ]
Ketoacidosis is a metabolic state caused by uncontrolled production of ketone bodies that cause a metabolic acidosis.While ketosis refers to any elevation of blood ketones, ketoacidosis is a specific pathologic condition that results in changes in blood pH and requires medical attention.
In severe diabetic ketoacidosis, the dipstix reaction based on sodium nitroprusside may underestimate the level of ketone bodies in the blood. It is sensitive to acetoacetate only, and the ratio of beta-hydroxybutyric to acetoacetate is shifted from a normal value of around 1:1 up to around 10:1 under severely ketoacetotic conditions, due to a ...
