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 (DKA) is one of the life-threatening severe complications of diabetes that demands immediate attention and intervention. [7] It is considered a medical emergency and can affect both patients with T1D (type 1 diabetes) and T2D (type 2 diabetes), but it is more common in T1D. [8]
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.
Type 2 diabetes is different in that it is usually caused by insulin resistance in the body in older patients leading to beta cell burnout over time, and is not prone to DKA. KPD is a condition that involves DKA like type 1, but occurs later in life and can regain beta cell function like type 2 diabetes.
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 maintain
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.
Kussmaul breathing is a deep and labored breathing pattern often associated with severe metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also kidney failure. It is a form of hyperventilation , which is any breathing pattern that reduces carbon dioxide in the blood due to increased rate or depth of respiration.
[1] [2] The delta ratio is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether mixed acid base disorder (metabolic acidosis) is present. The list of agents that cause high anion gap metabolic acidosis is similar to but broader than the list of agents that cause a serum osmolal gap .
