Final answer:
The recommended DM screening frequency for patients with a history of GDM and normal PP screening test results is to perform a GTT within 6-12 weeks postpartum and repeat the test every 1-3 years thereafter.
Step-by-step explanation:
The recommended DM screening frequency for patients who had a pregnancy with gestational diabetes mellitus (GDM) and normal postpartum (PP) screening test results may vary depending on the specific guidelines and individual patient factors. However, a common recommendation is to perform a glucose tolerance test (GTT) within 6-12 weeks postpartum and then repeat the test every 1-3 years thereafter.
This frequency is based on the increased risk of developing type 2 diabetes in women who had GDM during pregnancy. Regular screening allows for early detection and intervention, which can help reduce the risk of complications.
