We’ve complied a chart that differentiates between morning sickness and Hyperemesis Gravidarum.
| Morning Sickness | Hyperemesis Gravidarum (HG) |
| You lose little if any weight. | You lose 5-20 pounds or more. (> 5% of prepregnancy weight) |
| Nausea and vomiting do not interfere with your ability to eat or drink enough each day. |
Nausea and vomiting cause you to eat very little and get dehydrated from vomiting if not treated. |
| You vomit infrequently and the nausea is episodic but not severe. It may cause discomfort and misery. |
You vomit often and may vomit bile or blood if not treated. Nausea is usually moderate to severe and constant. |
| Dietary and/or lifestyle changes are enough to help you feel better most of the time. |
You will probably require fluid hydration through a vein and/or medications to stop the vomiting. |
| You typically will improve gradually after the first trimester, but may be a little queasy at times during the remainder of your pregnancy. |
You usually feel somewhat better by mid-pregnancy, but you may continue to be nauseous and/or vomit until late pregnancy. |
| You will be able to work most days and care for your family. | You will likely be unable to work for weeks or months, and may need help caring for yourself. |
