Extreme Morning Sickness

Has anyone heard of Hyperemesis Gravidarum, or extreme morning sickness? my friend is going through this, so i decided to do some research for her. I feel bad cause some people think its just regular morning sickness, but she has a horrible case of it where she is constantly sick. If there are any tips that i can share with her on this, let me know! thanks!

yeah I know you wrote this a year ago but I was diagnosed this. I am 9 weeks pregnant and still learning about it. I am readin a book about it. I dont know if you got all the info but I hope you did. I hope your friend got through it ok. I dont think I have a severe severe case of it but bad enough. I know some women go through hell. I am surprised no one responded to this. The post I put up about it actually didnt really get responses either. Maybe it is a tough subject? I dont know. But like I said I hope everything went well and that she still had a beautiful baby.
