Symptoms associated with the disorder may subside and recur (“wax and wane”) resulting in affected individuals being hospitalized more than once during their pregnancy. Some affected women may have a distinct odor to their breath (ketonic odor). Hyperemesis gravidarum often leads to hospitalization to restore lost fluids and nutrients to affected women.Īdditional symptoms associated with hyperemesis gravidarum may include rising pulse rate, excessive salivation (ptyalism), and a rapid heartbeat (tachycardia). In addition, frequent vomiting may lead to dehydration and vitamin and mineral deficit. Individuals with hyperemesis gravidarum experience severe and persistent nausea and vomiting that occur before the 20th week of pregnancy (gestation) and are severe enough to result in progressive weight loss of greater than 5% of their original body weight. Hyperemesis gravidarum may develop rapidly within a few weeks or gradually over a few months. While the cause of HG is likely multifactorial, currently, the most evidence exists for the placenta and appetite hormone GDF15 as playing an important role in the etiology of HG. Affected individuals can progress from mild or moderate nausea and vomiting to hyperemesis gravidarum. No specific line exists that separates hyperemesis gravidarum from NVP. Hyperemesis gravidarum represents the severe end of the continuum. 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. Nausea and vomiting of pregnancy (NVP), more widely known as morning sickness, is a common condition of pregnancy. As a result of frequent nausea and vomiting, affected women experience dehydration, vitamin and mineral deficit and the loss of greater than 5% of their original body weight. Hyperemesis gravidarum (HG) is a rare disorder characterized by severe and persistent nausea and vomiting during pregnancy that may necessitate hospitalization. 5 Myths About Orphan Drugs and the Orphan Drug Act.Information on Clinical Trials and Research Studies.Understanding bloating and distention.Abdominal bloating: A mysterious symptom /ibs/files/educational-gi-handouts/Abdominal%20Bloating.pdf (2013, August 29) my./symptoms/nausea/hic_nausea_and_vomiting.aspx
