Hello Study Participants!

We currently have completed and published 11 studies based on your survey results! Two of our most recent studies providing evidence for a genetic predisposition to HG, and showing HG can lead to long-term effects in children, have received worldwide media attention. This will help greatly to increase public awareness, make doctors take HG more seriously, as well as inspire more HG research. I have pasted links to summaries of our studies below. Thanks to you, we have made great progress but we still have a long way to go.

We currently have:

•1981 Eligible Participants (1317 HG, 664 Friend Controls)
•1600 Enrolled (had phone appointment and sent in signed consent forms)
•1084 DNAs (764 HG, 320 Friend Controls)
•892 complete the entire survey
•1239 survey sections one and two completed

We can NOT find the cause of HG until we have a minimum of 2,000 DNAs (1,000 HG and 1,000 friend controls)

PLEASE help us by checking the list below to make sure you have completed ALL the necessary steps and please refer your friends (HG and non-HG) to participate (as you can see we are very behind on the non-HG friends).

1) If you haven’t completed your SURVEY, please do so at

2) If you had HG, please have your FRIEND CONTROL email me at if you haven’t already. If possible, please refer extra friends.

3) If you haven’t sent in your CONSENT FORM, please do so as soon as possible.

4) If you haven’t sent in your SALIVA KIT, please do so as soon as possible.

5) If you had HG and haven’t sent your MEDICAL RECORDS relating to iv treatment, please do so as soon as possible.

6) If you have any problems/questions with the survey or anything else, please email me at

7) Please spread the word to your OBs and friends so we can get our 2,000 participants as fast as possible.

We have also begun a new study to determine medication effectiveness. If you are trying to conceive or newly pregnant and have had HG in a past pregnancy, please consider participating in this study by filling out this short survey as close to your first positive pregnancy test as possible and thereafter to let us know how medications effect your intake and nausea: ... 11-survey/

Thank you all very much for your time-each one of you is making a difference for generations of women and their children!

Unfortunately we are not covered for the cost of participants outside the US. There are no costs for participants in the US.
Thank you for your interest,
