title: [Prevalence of postpartum impaired glucose tolerance after gestational diabetes].
abstract: BACKGROUND
  gestational diabetes mellitus (GDM) affects 2 to 10% of pregnancies and it has been postulated as a variant of type 2 diabetes mellitus (DM2) because they share a similar pathophysioiogy. Approximately in 90% the carbohydrate intolerance resolves after pregnancy, however after 5 to 16 years after delivery women will have a risk of 17 to 63% to the development of type 2 diabetes mellitus.
  
  
  OBJECTIVE
  to determine the frequency of postpartum impaired glucose tolerance in women with previous GDM.
  
  
  METHODS
  125 patients with diagnosis of GMD were included, general data were captured, type of control during pregnancy and complications occurred. The women were instructed to undergo a postpartum oral glucose tolerance test of 75 g and 2 h, 6 weeks after their delivery date and they were classified into five groups: normal patients, type 2 diabetes mellitus, impaired glucose tolerance, impaired fasting glucose and combined both.
  
  
  RESULTS
  after follow up 13 women (10.4%) were diagnosed as DM2; 14 patients (11.2%) were classified as glucose intolerance; 16 (12.8%) were catalogued with impaired fasting glucose; 6 (4.8%) had both disorders; and 76 (60.8%) were diagnosed as healthy women.
  
  
  CONCLUSIONS
  the detection with a postpartum oral glucose tolerance test is necessary for the identification of the various types of disorders of the carbohydrate metabolism including DM2.
