Hyperemesis gravidarum (HG) begins between the fourth and sixth week of pregnancy. Symptoms usually improve somewhat by the 15th to 20th week of gestation, although some women continue to have frequent relapses throughout pregnancy. Most affected women have numerous episodes of vomiting throughout the day with few if any symptom-free periods, especially during the first three to four months. This leads to significant and rapid weight loss, dehydration, electrolyte disturbances, and nutritional deficiencies often requiring hospitalization.
If prolonged or more severe and not treated promptly, these can lead to kidney or liver damage. Numerous complications, some of which can be life-threatening are possible without adequate medical intervention. These women present to their medical providers with weight loss of five to 20+ pounds; however, since some are overweight to begin with, they may not appear malnourished. This is especially true as the pregnancy progresses. Early medical care may decrease severity of a woman's symptoms and lead to quicker recovery.
