Call 911 or emergency medical assistance
Call 911 if vomiting blood causes signs and symptoms of severe blood loss or shock, such as:
- Rapid, shallow breathing
- Dizziness or lightheadedness after standing up
- Blurred vision
- Cold, clammy, pale skin
- Low urine output
Seek immediate medical attention
Ask someone to drive you to 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, including death.
