General Discussion

Hyperemesis gravidarum (HG) is a rare disorder characterized by severe and persistent nausea and vomiting during pregnancy that may necessitate hospitalization. As a result of frequent nausea and vomiting, affected women experience dehydration, vitamin and mineral deficit, and the loss of greater than five percent of their original body weight.

Nausea and vomiting of pregnancy (NVP), more widely known as morning sickness, is a common condition of pregnancy. Many researchers believe that NVP should be regarded as a continuum of symptoms that may impact an affected woman's physical, mental and social well-being to varying degrees. Hyperemesis gravidarum represents the severe end of the continuum. No specific line exists that separates hyperemesis gravidarum from NVP; in most cases, affected individuals progress from mild or moderate nausea and vomiting to hyperemesis gravidarum. The exact cause of hyperemesis gravidarum is not known.
