What condition manifests after the 20th week of pregnancy and is identified by high blood pressure?

Preeclampsia is a condition that typically arises after the 20th week of pregnancy and is characterized by high blood pressure and often signs of damage to another organ system, most commonly the liver and kidneys. In addition to hypertension, preeclampsia can lead to the presence of protein in the urine, indicating kidney issues, and may also present with symptoms such as swelling, sudden weight gain, and headaches.

The condition is distinct from eclampsia, which is essentially a progression of preeclampsia and involves seizures. While hypertension itself is a broader term referring to high blood pressure, it does not specify the context of pregnancy nor the associated complications that can occur. Gestational diabetes, on the other hand, is a condition related to insulin resistance that develops during pregnancy and is not directly linked to blood pressure. Therefore, preeclampsia is the correct answer as it specifically describes the condition of high blood pressure that emerges in the latter half of pregnancy, accompanied by other potential symptoms indicating a risk to both the mother and the fetus.
