Eclampsia (from the Greek for "shining forth") is a life-threatening complication of pregnancy. It is characterized when a mother develops tonic-clonic seizures after suffering the symptoms of preeclampsia - high blood pressure and protein in the urine, where there is no other underlying organic cause for the seizures. The seizures eventually get worse and result in coma and death. It may also present with nausea, vomiting, headache and blindness. As it progresses, it often results in abdominal pain, liver failure and pulmonary edema together with multiple organ failure.
