Detection of pre-eclampsia is very important to prevent ecalmpsia because eclampsia is life-threatening condition. Pre-eclampsia manifests with high blood pressure but it is not related with the disease known as arterial hypertension. The etiology, or cause, of pre-eclampsia remains unknown. Unfortunately, there is no current way to predict the condition.

Morning sickness is a much more common event during pregnancy than pre-eclampsia. They aren't even related. It is very important to monitor blood pressure during the pregnancy especially in the second half of the pregnancy. If high blood pressure is noticed, proteins in the urine should be also examined.
