Editors Notes

  • Pre-eclampsia is a serious complication of pregnancy associated with poor health, or even death, for the mother and baby.
  • Pre-eclampsia is identified by raised blood pressure and protein in the urine during the second half of pregnancy.
  • In the past, a low-salt diet was often recommended, in the belief that it would help to prevent pre-eclampsia.
