What condition is defined by pregnancy-induced hypertension occurring after 20 weeks?

The condition defined by pregnancy-induced hypertension occurring after 20 weeks is preeclampsia. Preeclampsia is characterized by high blood pressure and signs of damage to other organ systems, often the kidneys or liver, in a pregnant woman. It typically occurs after the 20th week of pregnancy and can lead to serious complications for both the mother and the baby if left untreated.

The distinguishing features of preeclampsia often include symptoms such as swelling, protein in the urine, and hypertension, making it critical for monitoring during prenatal care. Effective management is essential to mitigate risks for both the mother and the fetus, and it is distinct from conditions such as eclampsia, which involves seizures and is a severe progression of preeclampsia.

Gestational diabetes refers to high blood sugar that develops during pregnancy and resolves after delivery, which is unrelated to hypertension. Placenta previa occurs when the placenta partially or completely covers the cervix, creating risks for bleeding during pregnancy and labor, but does not involve hypertension.
