C. 24 weeks
D. 32 weeks
E. 34 weeks
Answer and topic summary
The answer is C. 24 weeks
Prenatal care is extremely important. Screening for gestational diabetes is routinely done in pregnant patients at 24 weeks of gestation (typically until 28 weeks). Pregnancy is associated with insulin resistance, mostly because of the placenta’s secretion of human placental lactogen. There are bad consequences of gestational diabetes, so it is critical it is diagnosed and treated adequately.
The initial test is a one-hour 50-gram oral glucose tolerance test (GTT). A positive test >135 mg/dL. If a patient tests positive, they need to undergo the second test, which is a three-hour 100 mg oral GTT. The cut-offs are debated, but generally the following are positive results: fasting > 95 mg/dL, 1-hour >180 mg/dL, 2-hour >155 mg/dL, 3-hour >140 mg/dL.
