What determines whether hypertension in a pregnant woman is classified as gestational?

The classification of hypertension in a pregnant woman as gestational is primarily determined by the timing of diagnosis. Gestational hypertension is specifically defined as hypertension that develops after 20 weeks of pregnancy and resolves after delivery, distinguishing it from pre-existing hypertension or chronic hypertension, which may be present before pregnancy or diagnosed earlier in the gestation period.

Understanding the timing is crucial because it impacts diagnosis and management. If hypertension is identified before 20 weeks, it may not be categorized as gestational but instead may be considered chronic. This timing element is essential in providing appropriate care and determining potential risks for both the mother and the fetus.

The duration of hypertension, presence of other symptoms, and underlying medical history can influence management and prognosis but do not play a direct role in the classification of hypertension as gestational. Thus, timing is key in differentiating gestational hypertension from other forms of hypertension during pregnancy.
