When does gestational hypertension typically begin?

• A. Before 12 weeks gestation
• B. Between 20 and 30 weeks gestation
• C. After 20 weeks gestation
• D. After childbirth

Answer: (C)

Gestational hypertension is defined as the development of high blood pressure after 20 weeks of pregnancy, specifically in women who did not have hypertension prior to pregnancy. This condition typically arises during the latter half of pregnancy, which aligns with option C. Recognizing the onset timing is crucial for monitoring and managing potential risks associated with high blood pressure during pregnancy, such as preeclampsia.

The other options are outside the typical onset timeframe; for example, gestational hypertension does not occur before 12 weeks, which indicates that preexisting hypertension or other factors may be at play before this point. Similarly, while hypertension can manifest between 20 and 30 weeks, the key defining feature is that it occurs after reaching the 20-week mark. The period after childbirth is relevant for postpartum hypertension but does not apply to gestational hypertension since the condition is specifically identified during pregnancy.
