Research on HG's short- and long-term effects is desperately needed and needed now. We need to do more to find a cure for this disease that has such devastating effects on a growing number of soon-to-be mothers.
Signs & Symptoms
Symptoms usually begin around week 4-6 and peak between 9-13 weeks, however, some women report changes beginning just a few days following conception. Early changes may include changes in taste or smell perception, nausea, vomiting, and excessive sleepiness. Often there is resolution or at least significant improvement somewhere around 14-20 weeks, though at least 10-20% of hyperemetic women will continue to have significant nausea/vomiting until late pregnancy or delivery.
Treatment (antiemetics, nutrition) should be weaned very slowly after the mother is asymptomatic for two or more weeks to prevent relapse or worsening of symptoms.
