Eclampsia is a severe complication of preeclampsia. It’s a rare but serious condition where high blood pressure results in seizures during pregnancy.
Seizures are periods of disturbed brain activity that can cause episodes of staring, decreased alertness, and convulsions (violent shaking). Eclampsia affects about 1 in every 200 women with preeclampsia. You can develop eclampsia even if you don’t have a history of seizures.
Because preeclampsia can lead to eclampsia, you may have symptoms of both conditions. However, some of your symptoms may be due to other conditions, such as kidney disease or diabetes. It’s important to tell your doctor about any conditions you have so they may rule out other possible causes.
