How does gestational hypertension differ from preeclampsia in terms of proteinuria?

Gestational hypertension is characterized by high blood pressure that develops after the 20th week of pregnancy and does not involve significant proteinuria. In contrast, preeclampsia is diagnosed when gestational hypertension is accompanied by proteinuria, indicating the presence of excess protein in the urine. The occurrence of proteinuria in preeclampsia suggests impairment of kidney function and is a critical aspect that helps differentiate it from gestational hypertension.

The presence of protein in the urine is significant because it indicates a potential complication that can affect both the mother and the fetus, necessitating closer monitoring and management. Understanding this difference is crucial for recognizing the severity of conditions affecting pregnant individuals and ensuring appropriate treatment approaches.
