<unk>  are health problems that are related to pregnancy.<unk>  that occur primarily during childbirth are termed obstetric labor<unk> , and problems that occur primarily after childbirth are termed puerperal disorders. Severe<unk> , childbirth, and the puerperium are present in 1.6% of mothers in the US, and in 1.5% of mothers in Canada. In the immediate postpartum period (puerperium), 87% to 94% of women report at least one health problem. Long-term health problems (persisting after six months postpartum) are reported by 31% of women. In 2016,<unk> , childbirth, and the puerperium resulted globally in 230,600 deaths, down from 377,000 deaths in 1990. The most common causes of maternal mortality are maternal bleeding, postpartum infections including maternal sepsis, hypertensive diseases of pregnancy, obstructed labor, and pregnancy with abortive outcome, which includes miscarriage, ectopic pregnancy, and elective abortion. There is no clear distinction between<unk>  and symptoms and discomforts of pregnancy. However, the latter do not significantly interfere with activities of daily living or pose any significant threat to the health of the mother or baby. Still, in some cases, the same basic feature can manifest as either a discomfort or a<unk> depending on the severity. For example, mild nausea may merely be a discomfort (morning sickness), but if severe and with vomiting causing water-electrolyte imbalance it can be classified as a pregnancy<unk> (hyperemesis gravidarum).
