Periprocedural Care

Patient Education & Consent

Patients should be informed of the reasons for screening and process of the OGTT test. [17] A thorough discussion of the ramifications of an abnormal test should ensue as well. Patients should be aware that in the event of an abnormal test, treatment needs to begin immediately, whether that entails dietary modifications, oral hypoglycemic agents, or insulin.


Patient Preparation

Patients should be fasting at least 8 hours prior to testing. No preparatory diet is needed.


Monitoring and Follow up

In the event of an abnormal 75-g OGTT, patients should be counseled on gestational diabetes mellitus and receive nutritional counseling. If postprandial blood sugars still remain elevated and glycemic control is less than ideal, medication should be initiated.

Following delivery, patients should be screened for persistent diabetes 6-12 weeks postpartum, as an increased risk of developing type 2 diabetes, type 1 diabetes, and cardiovascular disease exists. [7, 11] Following that, these patients should have lifelong screening for prediabetes or diabetes development every 3 years. [11, 18, 19]
