Diabetic ketoacidosis (DKA) is characterised by a biochemical triad of hyperglycaemia, ketonaemia, and acidaemia, with rapid symptom onset.
Common symptoms and signs include polyuria, polydipsia, polyphagia, weakness, weight loss, tachycardia, dry mucous membranes, poor skin turgor, hypotension, and, in severe cases, shock.
Successful treatment includes correction of volume depletion, hyperglycaemia, electrolyte imbalances, and comorbid precipitating events, with frequent monitoring.
Complications of treatment include hypoglycaemia, hypokalaemia, hypoxaemia, and rarely pulmonary oedema.
Cerebral oedema, a rare but potentially rapidly fatal complication, occurs mainly in children. It may be prevented by avoiding overly rapid fluid and electrolyte replacement.
Diabetic ketoacidosis (DKA) is an acute metabolic complication of diabetes that is potentially fatal and requires prompt medical attention for successful treatment. It is characterised by absolute insulin deficiency and is the most common acute hyperglycaemic complication of type 1 diabetes mellitus.
