Morning Sickness vs. Hyperemesis Gravidarum: What's the Difference?

Written by Kristy Beard, MSN, APRN, FNP-C — Board-Certified Family Nurse Practitioner and Founder of Elevate Health and Wellness, serving patients across the Gulf Coast in Gautier, MS and Foley, AL.

Nausea in Pregnancy: A Spectrum

Nausea during pregnancy affects up to 80% of pregnant women according to the American College of Obstetricians and Gynecologists (ACOG). For most women, it is an unpleasant but manageable part of the first trimester that improves by weeks 12 to 14. For a smaller subset — estimated at 0.3% to 2% of pregnancies — nausea and vomiting become severe, persistent, and medically serious. This is hyperemesis gravidarum (HG).

What Is Typical Morning Sickness?

Typical pregnancy nausea begins around weeks 6 to 8, peaks around weeks 9 to 10, and resolves by the end of the first trimester for most women. Women with typical morning sickness can generally keep some food and fluid down, may feel better with dietary adjustments or vitamin B6, and experience minimal weight loss if any.

What Is Hyperemesis Gravidarum?

HG is characterized by severe persistent nausea and vomiting, loss of more than 5% of pre-pregnancy body weight, severe dehydration, electrolyte imbalances, and inability to tolerate any food or liquid for sustained periods. Many women with HG require hospitalization or outpatient IV therapy. Research published in the Journal of Midwifery and Women's Health shows that women with HG also experience high rates of anxiety, depression, and pregnancy-related psychological distress.
