What the research identifies as fetal risk factors are inherent in hyperemetic pregnancies," said Kimber MacGibbon, RN and founder of the HER (Hyperemesis Education and Research) Foundation in the US.
In fact, many hyperemetic women lose 10% or more of their body weight and require risky interventions to survive.
Despite current care, hyperemetic mothers have greater risk of pregnancy complications including preeclampsia, preterm labor, and spontaneous abortion.
With regard to the etiology of the hyperthyroidism in hyperemesis, not all studies show a difference in serum human chorionic gonadotropin (hCG) concentration between those hyperemetic
subjects with hyperthyroidism and those without (6).
