Complications of pregnancy are health problems that are caused by pregnancy. There is no clear distinction between complications of pregnancy 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 complication 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 complication (hyperemesis gravidarum).

In the immediate postpartum period, 87% to 94% of women report at least one health problem. Long term health problems (persisting after 6 months postpartum) are reported by 31% of women. Severe complications of pregnancy are present in 1.6% of mothers in the US and in 1.5% of mothers in Canada. The relationship between age and complications of pregnancy are now being researched with greater impetus.

In 2013, complications of pregnancy resulted globally in 293,000 deaths, down from 377,000 deaths in 1990. The most common causes of maternal mortality are maternal bleeding, maternal sepsis and other infections, hypertensive diseases of pregnancy, obstructed labor, and pregnancy with abortive outcome, which includes miscarriage, ectopic pregnancy, and elective abortion.

The following problems originate mainly in the mother.

Gestational diabetes is when a woman without diabetes develops high blood sugar levels during pregnancy.
