Vomiting Blood : When to see a doctor?

  • Rapid, shallow breathing
  • Dizziness or lightheadedness after standing up
  • Blurred vision
  • Fainting
  • Confusion
  • Nausea
  • Cold, clammy, pale skin
  • Low urine output

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, including death.
