Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. [1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [1]
Ketone bodies are produced by the liver during periods of caloric restriction of various scenarios: low food intake , carbohydrate restrictive diets, starvation, prolonged intense exercise, [5] alcoholism, or during untreated (or inadequately treated) type 1 diabetes mellitus. Ketone bodies are produced in liver cells by the breakdown of fatty ...
medications, alcoholic beverages, undiagnosed diabetes 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.
Ketoacidosis is a pathological state of uncontrolled production of ketones that results in a metabolic acidosis, with serum ketone levels typically in excess of 3 mM. Ketoacidosis is most commonly caused by a deficiency of insulin in type 1 diabetes or late stage type 2 diabetes but can also be the result of chronic heavy alcohol use ...
It is seen in conditions in which the body produces excess ketones as an indication that it is using an alternative source of energy. It is seen during starvation or more commonly in type 1 diabetes mellitus. Production of ketone bodies is a normal response to a shortage of glucose, meant to provide an alternate source of fuel from fatty acids.
Diabetic coma is a medical emergency in which a person with diabetes mellitus is comatose (unconscious) because of one of the acute complications of diabetes: [24] [25] Severe diabetic hypoglycemia Diabetic ketoacidosis advanced enough to result in unconsciousness from a combination of severe hyperglycemia , dehydration and shock , and exhaustion
Individuals with diabetes mellitus can experience overproduction of ketone bodies due to a lack of insulin. Without insulin to help extract glucose from the blood, tissues the levels of malonyl-CoA are reduced, and it becomes easier for fatty acids to be transported into mitochondria, causing the accumulation of excess acetyl-CoA.
Ketone bodies are elevated in the blood after fasting, including a night of sleep; in both blood and urine in starvation; in hypoglycemia, due to causes other than hyperinsulinism; in various inborn errors of metabolism, and intentionally induced via a ketogenic diet, and in ketoacidosis (usually due to diabetes mellitus).
