When to see a doctor
By Mayo Clinic staff
Call 911 or emergency medical assistance
Seek emergency help immediately if you're vomiting blood and have any signs of severe blood loss or shock:
- Rapid, shallow breathing
- Dizziness or lightheadedness after standing up
- Blurred vision
- Fainting
- Confusion
- Nausea
- Cold, clammy, pale skin
- Low urine output
Seek immediate medical attention
Ask someone to drive you to urgent care or the emergency room if you notice blood in your vomit or begin vomiting blood. It's important to quickly identify the underlying cause of the bleeding and prevent more severe blood loss and other complications.
