Which of the following can be a consequence of untreated preeclampsia?

Untreated preeclampsia can lead to several serious complications, one of which includes the potential for the death of both the mother and the infant. Preeclampsia is characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys, typically occurring after the 20th week of pregnancy. If not managed effectively, it can progress to eclampsia, which is characterized by seizures, and can cause life-threatening issues for both the mother and the fetus, including organ failure, placental abruption, and fetal growth restriction.

The other options do not accurately reflect the severe risks associated with untreated preeclampsia. Increased appetite for sweets is not a recognized consequence of this condition. A normal delivery process is often compromised in cases of severe preeclampsia, where delivery may need to be expedited for the safety of both mother and child. Additionally, extended pregnancy duration is typically not a result of preeclampsia, as the condition often necessitates an earlier delivery to mitigate risks. Thus, the most significant and dire consequence of untreated preeclampsia is indeed the potential for maternal and infant mortality.
