Condition

Nausea & vomiting

The unpleasant feeling of needing to be sick, with or without vomiting — a symptom of many causes, from pregnancy and motion to medication and surgery.

Affects Stomach

See a clinician

Some causes of nausea & vomiting need medical care, not self-treatment. Seek help for any of these:

  • Vomiting that prevents keeping down any fluids for more than ~24 hours, or signs of dehydration (little urination, dizziness, rapid heartbeat).
  • Blood in vomit, or vomit that looks like coffee grounds — possible GI bleeding.
  • Green/yellow bilious vomiting with severe abdominal pain, or vomiting after a head injury.
  • Vomiting with high fever, stiff neck, severe headache, or confusion.
  • Severe pregnancy vomiting with weight loss and dehydration (hyperemesis gravidarum) — needs obstetric care.

What may help

Remedies studied for nausea & vomiting, ranked by strength of evidence.

  • B
    Ginger herb

    Reduces nausea of pregnancy and after surgery, and acute chemotherapy nausea — though it helps the nausea more reliably than the vomiting.

  • B
    Vitamin B6 nutrient

    Reduces nausea of pregnancy across trials and reviews (a recommended first-line therapy, often with doxylamine); the effect on vomiting frequency is weaker and less consistent.

For everyday nausea the cause usually settles on its own. Ginger has the broadest trial support (pregnancy and postoperative nausea especially), and vitamin B6 is a guideline-backed option for pregnancy nausea — though both help the nausea more reliably than the vomiting.
