What Is Hyperemesis Gravidarum?
Causes

The main cause of hyperemesis gravidarum stems from the drastic increase of hormones a woman experiences during pregnancy. There is typically a surge of human chorionic gonadotropin (HCG), used by pregnancy tests, which the uterus produces for the body to support a healthy pregnancy. This is also the cause for a typical case of morning sickness. There is little evidence to support what makes a woman's morning sickness elevate to the level of hyperemesis gravidarum, but it is suspected a previous issue with this or a pregnancy involving multiples can be contributing factors.
