Preeclampsia is a systemic pregnancy syndrome that usually occurs in the third trimester. Preeclampsia is also the early stage of eclampsia and can cause a number of dangerous complications.

Preeclampsia is common in pregnant women after 20 weeks of pregnancy and with normal blood pressure. If left untreated, preeclampsia can lead to serious complications, even death, for both mother and baby. Therefore, recognizing the early signs of preeclampsia is extremely important for timely intervention, ensuring the health of mother and baby.
