Disorders associated with hypertension such as eclampsia and preeclampsia are further characterised by symptoms such as proteinuria, oedema or high body temperature.

This definition of hypertensive disorder in pregnancy from the Society of Obstetric Medicine in Australia and New Zealand (SOMANZ) (Lowe et al. 2014) aligns with the definition of the International Society for the Study of Hypertension in Pregnancy (ISSHP).
