What defines preeclampsia in pregnancy?

Preeclampsia is a serious condition that typically occurs after the 20th week of pregnancy and is characterized primarily by high blood pressure and signs of organ damage, particularly involving the liver and kidneys. The defining features of preeclampsia include a blood pressure reading of 140/90 mmHg or higher, along with the presence of protein in the urine or other symptoms of systemic involvement, such as elevated liver enzymes or low platelet count.

This condition can lead to severe complications for both the mother and the fetus if not adequately managed. While fatigue can occur in pregnancy, it is not a key indicator of preeclampsia. Similarly, normal blood pressure or mild swelling does not reflect the serious nature of preeclampsia. Severe headaches and nausea can happen during pregnancy for various reasons, but they alone do not meet the diagnostic criteria for preeclampsia without the presence of elevated blood pressure and organ dysfunction. Thus, recognizing high blood pressure and associated organ damage is crucial for the diagnosis and management of preeclampsia in pregnancy.
