Atypical Feature of Diabetic Ketoacidosis with Low or Normal Plasma Glucose: a Narrative Review

Diabetic Ketoacidosis (DKA) is a well-known emergency in diabetic patients. In a subgroup of patients ketoacidosis is present but is not accompanied by the marked hyperglycemia considered part of the diagnostic criteria for DKA. This is known as Euglycemic DKA (EuDKA). Evidence acquisition: We searched the PubMed for the existing literature on the topic of normoglymic ketoacidosis, including its prevalence, pathogenesis, and treatment.  

The study showed that there are many reports of the cases in which diabetic patients developed ketoacidosis without experiencing hyperglycemia. Several predisposing factors have been proposed but the precise pathophysiologic mechanisms are still under investigation. Some pathways have been suggested. Timely diagnosis is of paramount importance. Treatment is similar to DKA. 

EuDKA is a medical emergency that should be considered when evaluating a diabetic patient with ketoacidosis. It should be diagnosed and treated promptly.
