What is one major complication of untreated eclampsia?

One major complication of untreated eclampsia is the occurrence of seizures that can threaten both the mother and the baby. Eclampsia is characterized by the onset of seizures in a patient with preeclampsia, which involves high blood pressure and signs of damage to organ systems. The seizures can lead to significant risks, including maternal injury, brain damage, or even maternal death. Additionally, fetal complications can arise due to lack of oxygen and nutrients during these seizure events, which can adversely affect fetal well-being.

While other conditions such as gestational diabetes and placenta previa are serious in their own right, they are not direct complications resulting from eclampsia. Similarly, increased blood pressure is a symptom of eclampsia rather than a complication that arises from it. Therefore, the impact of seizures is the most critical concern in the context of untreated eclampsia.
