There is a strong epidemiological association between maternal obesity and gestational diabetes mellitus (GDM). Since the publication of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study on women with mild hyperglycemia in 2008, new criteria have been introduced in maternity services internationally for the diagnosis of GDM. As a result, the diagnosis of GDM may be made in one-third of obese women (n= 68). The aim of this review was to examine the interplay between maternal obesity and GDM in light of the HAPO study and the subsequent revised diagnostic criteria. Obesity and GDM are important obstetric risk factors because they both are potentially modifiable. However, the new international criteria for the diagnosis of GDM have serious resource implications for maternity services provided to the large number of women attending for care in developed countries. Further consideration needs to be given as to whether obese women with mild hyperglycemia need to be referred to a multidisciplinary team antenatally if they do not require insulin treatment.
