Abstract Aims 

To determine the occurrence of diabetic ketoacidosis (DKA) in adult Type 2 and Type 1 diabetic patients in Northern Sweden and to determine whether DKA presents with a different clinical picture in Type 2 compared with Type 1 diabetic subjects. Methods 

All adult patients from a hospital catchment area in Northern Sweden with diagnosed DKA episodes during 1997–2000 were included in a retrospective study. Medical records and laboratory reports were analysed. Results 

During the years 1997 to 2000, the average annual incidence rate for DKA was 5.9 per 100 000 adult inhabitants. Twenty-five patients developed DKA, eight (32%) had Type 2 diabetes, while 17 (68%) had Type 1 diabetes. Type 2 diabetic patients with DKA were older and had higher levels of C-peptide than Type 1 diabetic patients. On admission because of DKA, a similar degree of hyperglycaemia was present in Type 1 and Type 2 patients. Metabolic acidosis was more severe in Type 1 compared with Type 2 diabetic patients. In 50% of the Type 2 diabetic patients, diabetes was diagnosed at the episode of DKA. Conclusions 

DKA occurs in Caucasian Type 2 diabetic patients within a Swedish population. Although the frequency of DKA is much higher in Type 1 diabetic patients, Type 2 diabetes may account for as much as one-third of the overall DKA cases.
