How fast will toxemia go away after delivery?

Less than 24 hours. Toxemia or pre-eclampsia complicates about 8% of pregnancies. The cure for toxemia is delivery and the resolution usually starts in less than 24 hours. However, it can take days or weeks for the disorder to completely resolve - and it could recurr even several weeks after delivery after it has seemed to go away. Importantly, some cases of toxemia do not even start until after delivery.
