What is hyperemesis gravidarum?
Hyperemesis gravidarum is when you're pregnant and you throw up (vomit) a lot
You throw up so much that you lose weight and become dehydrated (don't have enough water or other fluid in your body)
Some vomiting in pregnancy is common. It's often called "morning sickness." If you have morning sickness, you feel uncomfortable but continue to gain weight and stay hydrated. Doctors aren't sure why some women have severe vomiting.
Hyperemesis gravidarum is different from ordinary morning sickness because it's so severe
You'll need IV fluid (directly into your vein) and usually medicines to stop the vomiting
Usually, hyperemesis gravidarum stops by 16 to 18 weeks of pregnancy
If it lasts for a long time or is very severe, it can cause problems with your liver

After you’ve stopped vomiting, you’ll get fluids to drink and small amounts of bland foods to eat
If you start throwing up again, this process starts over
Rarely, if you keep vomiting and losing weight, you may be fed through a tube. The tube goes through your nose and down your throat into your belly.
If you keep vomiting and losing weight and have liver problems, you may want to consider ending your pregnancy. You can talk with your doctor about this option.
