Data showing the effectiveness of preemptive treatment for hyperemesis gravidarum and severe morning sickness will be presented by researchers in a study.

Previous treatment for HG was to administer medication (Diclectin in Canada, Bendectin in the US) at the onset of symptoms, but this course of treatment provided little, if any, relief.
Drs. Gideon Koren and Caroline Maltepe, of The Hospital for Sick Children in Toronto, ON, Canada, divided 59 women with a history of HG or severe morning sickness into two groups: one would begin taking Diclectin as soon as the pregnancy was discovered; the second group would begin treatment at the onset of HG symptoms.
They found the group receiving treatment before the onset of symptoms, had a significant decrease in risk of severe nausea and vomiting.
"This is the first time there is an answer," said Dr. Koren. "Women who have experienced hyperemesis are so traumatized by it, they are afraid of a second pregnancy."
Dr. Koren, who with Dr. Maltepe runs a severe morning sickness counseling program at The Hospital for Sick Children, says the drug used to treat HG is safe to take throughout pregnancy or even before conception.
