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] A person's breath may develop a specific "fruity" or acetone smell. [1]
Diabetic ketoacidosis advanced enough to result in unconsciousness from a combination of severe hyperglycemia, dehydration and shock, and exhaustion; Hyperosmolar nonketotic coma in which extreme hyperglycemia and dehydration alone are sufficient to cause unconsciousness.
Diabetic ketoacidosis (usually type 1) advanced enough to result in unconsciousness from a combination of a severely increased blood sugar level, dehydration and shock, and exhaustion; Hyperosmolar nonketotic coma (usually type 2) in which an extremely high blood sugar level and dehydration alone are sufficient to cause unconsciousness.
The most common cause of ketoacidosis is a deficiency of insulin in type 1 diabetes or late-stage type 2 diabetes. This is called diabetic ketoacidosis and is characterized by hyperglycemia, dehydration and metabolic acidosis. Other electrolyte disturbances such as hyperkalemia and hyponatremia may also be present.
The most common causes of high anion gap metabolic acidosis are: ketoacidosis, lactic acidosis, kidney failure, and toxic ingestions. [3] Ketoacidosis can occur as a complication of diabetes mellitus (diabetic ketoacidosis), but can occur due to other disorders, such as chronic alcoholism and malnutrition. In these conditions, excessive free ...
This state can be either physiologic or pathologic; physiologic ketotic hypoglycemia is a common cause of hypoglycemia in children, often in response to stressors such as infection or fasting. [1] Pathologic ketotic hypoglycemia is typically caused by metabolic defects, such as glycogen storage disorders .
In fasting adults, blood plasma glucose should not exceed 7 mmol/L or 126 mg/dL. Sustained higher levels of blood sugar cause damage to the blood vessels and to the organs they supply, leading to the complications of diabetes. [48] Chronic hyperglycemia can be measured via the HbA1c test. The definition of acute hyperglycemia varies by study ...
[25] [26] Adults with type 1 diabetes tend to have more varied symptoms, which come on over months, rather than days or weeks. [27] [26] Prolonged lack of insulin can cause diabetic ketoacidosis, characterized by fruity breath odor, mental confusion, persistent fatigue, dry or flushed skin, abdominal pain, nausea or vomiting, and labored breathing.
