What is Nausea?

Nausea is a very common symptom that accompanies many conditions. It may be temporary after a heavy meal or as a result of motion sickness, or it may be associated with a gastrointestinal infection or other conditions.

Most simple episodes of nausea resolve on their own, but persistent nausea or nausea linked to other symptoms deserves attention.

Possible causes

  • Indigestion or overeating.
  • Viral or bacterial gastrointestinal infection.
  • Motion sickness during travel.
  • Early pregnancy in women.
  • Certain medications or strong odors.

These are common general causes; persistent nausea may require medical evaluation.

When to see a doctor

Consult your doctor if:

  • Nausea or vomiting persists for more than one or two days.
  • It prevents you from drinking fluids and signs of dehydration appear.

Seek emergency care immediately if you experience bloody vomit or vomit the color of coffee grounds, nausea accompanied by chest pain or severe sudden headache, confusion, or severe abdominal pain.
