Introduction Gestational Diabetes (GDM) is a known risk factor for the development of type 2 diabetes. Postnatal Diabetes screening is recommended. The screening gold standard for this purpose is the 75 g Oral Glucose Tolerance Test (OGTT) performed at 6–12 weeks postnatal. The main drawback is patient non-adherence with the test. In our 2014 −2015 study the hospital population demonstrated that only 17% of patients adhered to the test. Objectives Improve patient education regarding GDM with its relevance to Type 2 Diabetes during the Antenatal period. Determine whether education improves compliance with the postnatal OGTT. Calculate the number of abnormal OGTTs. Methods Two year, prospective study from 1st January 2016 till 31st December 2017. All women diagnosed with GDM in pregnancy were seen by the diabetes educators. Importance of a postnatal OGTT was emphasized. The physician was instructed to place orders for the 75 gram postnatal OGTT on discharge. A reminder SMS was sent one day before the OGTT appointment. Results The postnatal OGTT adherence became 100%. All patients having an antenatal OGTT in our hospital attended their postnatal OGTT appointement. Those patients who were diagnosed with GDM elsewhere and subsequently delivered in Corniche Hospital also attended the postnatal OGTT. The Abnormal OGTTs were 7.7%. The Diabetes Educators now have focused sessions in the postnatal visit where the OGTT results are discussed and acted upon. Discussion The postnatal OGTT remains an important tool in the detection of type 2 diabetes. If used properly it allows: Early detection of Diabetes allowing early intervention and prevention of future complications.
