What is the classic triad of Pre-eclampsia?

The classic triad of pre-eclampsia is characterized by hypertension, proteinuria, and edema; however, the most commonly recognized features for diagnosis include hypertension and proteinuria, with edema being a potential symptom rather than a diagnostic criterion. The correct focus for pre-eclampsia is on the presence of high blood pressure and excess protein in the urine after the 20th week of pregnancy.

While edema may occur, particularly in the lower extremities, it is not a definitive sign of pre-eclampsia on its own. Severe headache is often associated with pre-eclampsia and can signal complications, but it is not part of the classic triad. Ultimately, the appropriate combination leading to the diagnosis is hypertension and proteinuria, which are critical to diagnosing this condition effectively. Understanding these primary features is vital for recognizing and managing pre-eclampsia.
