Term Hyperemesis Gravidarum
Code YF-3000.6840-300
Definition A rare disorder, also known as HG, that is characterized by severe and persistent nausea and vomiting during pregnancy. While nausea and vomiting occur in 50 to 90% of all pregnancies, HG is estimated to occur in .5 to 2% of pregnant women and may necessitate hospitalization. Affected women may experience dehydration, electrolyte imbalances, vitamin and mineral deficits and significant weight loss (greater than 5% of their original body weight). Additional symptoms may include rising pulse rate, excessive salivation (ptyalism), and a rapid heartbeat (tachycardia). Some affected women may have a distinct odor to their breath (ketonic odor). The condition can occur in any pregnancy, but is a little more likely in women who are pregnant with more than one child or are prone to motion sickness. Symptoms may subside and recur resulting in affected individuals being hospitalized more than once during their pregnancy.
