Signs & Symptoms
Symptoms such as changes in taste or smell, nausea and vomiting usually begin around week 4-6 and peak between 9-13 weeks. Onset of symptoms may occur before the pregnancy is confirmed by an elevation in hCG level (positive pregnancy test).
If onset is later than the first trimester, it is more likely due to liver or gall bladder dysfunction, or the physical changes of pregnancy, and thus is not considered HG.
Typically, there is resolution or at least significant improvement somewhere around 14-20 weeks, however, some women (10-20% or more) continue to require significant care for their entire pregnancy. Our Severity of Weightloss Calculator helps mothers calculate their percentage of weightloss.
HG often recurs and follows similar patterns in future pregnancies, though severity may vary each time.
