what is preeclampsia in pregnancy

Preeclampsia is a serious complication of pregnancy characterized by high blood pressure, high levels of protein in the urine (proteinuria), or other signs of organ damage. It usually develops after 20 weeks of pregnancy and can lead to serious, even fatal, complications for both the mother and the baby if left untreated. The exact cause of preeclampsia is not fully understood, but it is believed to involve problems with the development and function of blood vessels in the placenta, which can lead to irregular regulation of blood pressure in the mother. Other symptoms of preeclampsia may include swelling, headaches, and blurred vision. Preeclampsia can also affect other organs in the body and may require early delivery of the baby, depending on the severity of the condition and the gestational age. It is a leading cause of preterm birth and can increase the risk of maternal complications such as postpartum hemorrhage, heart disease, diabetes, and kidney disease later in life
