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.
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.
The result is a rate of ketone production higher than the rate of ketone disposal, and a decrease in blood pH. [12] In extreme cases the resulting acetone can be detected in the patient's breath as a faint, sweet odor. There are some health benefits to ketone bodies and ketogenesis as well.
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
The resulting very high levels of ketone bodies lower the pH of the blood plasma, which reflexively triggers the kidneys to excrete urine with very high acid levels. The high levels of glucose and ketones in the blood also spill passively into the urine (due to the inability of the renal tubules to reabsorb glucose and ketones from the tubular ...
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.
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.
