What Does Blood Loss Feel Like?

What are the first signs of internal bleeding?

  • Stiff neck.
  • Confusion.
  • Stroke symptoms (vision loss, weakness, and slurred speech)
  • Lightheadedness.
  • Shortness of breath.
  • Low blood pressure.
  • Blood in the stool.

Can you be bleeding internally and not know it?

Internal bleeding is a symptom of an injury, condition, or disease. You won’t have internal bleeding without an underlying reason. Recognizing the symptoms of internal bleeding can help you and your doctor understand what’s bleeding, why it’s bleeding, and what conditions could be contributing to the problem.

How long does it take to recover from blood loss?
