Full Definition
Gestational diabetes mellitus (GDM) is a form of diabetes that develops during pregnancy in women who did not have diabetes before conception. It typically occurs in the second or third trimester when hormonal changes increase insulin resistance. GDM affects approximately 2-10% of pregnancies and increases the risk of complications for both mother and baby, including macrosomia, polyhydramnios, and increased cesarean delivery rates. Diagnosis is made through glucose tolerance testing, usually performed between 24-28 weeks of gestation.
Usage
Usage note: Distinguish from pre-existing diabetes; use GDM abbreviation after first mention.
