HYPEREMESIS gravidarum, or excessive nausea and vomiting that persists beyond the 20th week of pregnancy, causes weight loss of more than 5% of prepregnancy body weight, dehydration, metabolic acidosis from starvation, alkalosis from loss of hydrochloric acid, and hypokalemia. The cause of hyperemesis gravidarum isn't known, but its effects—decreased placental blood flow, decreased maternal blood flow, and acidosis—can threaten the health of mother and fetus. Dehydration also can cause preterm labor. 1
