Most cases of morning sickness are harmless, although quite annoying. In some cases, though, this condition can become severe, known as hyperemesis gravidarum (HG). HG can require hospitalization.

When is hospitalization necessary?

Signs of HG that warrant medical attention include (but are not limited to) the following:

  • Severe nausea
  • Persistent vomiting
  • Inability to hold liquids down
  • Decreased urine output
  • Urine that is dark in color
  • Vomiting blood or vomit that looks like coffee grounds
  • Unintended weight loss
  • Excess salivation
  • Dehydration
  • Constipation

Anyone who has any concerns about their pregnancy—including morning sickness—should contact their medical provider.
