Nose Bleed Symptoms & Diagnosis


Nosebleed symptoms differ, depending on where in the nose the bleeding begins.

  • Anterior nosebleed—produces blood flow from one nostril when the patient sits or stands. Blood may pass down the throat if the person is coughing or blowing the nose.
  • Posterior nosebleed—causes bleeding down the back of the mouth and throat. When the patient leans forward, the blood may flow from the nostril. Blood flow may be fast or slow.


The doctor will ask about your symptoms and medical history, and perform a physical exam. Your pulse and blood pressure will be taken carefully, because severe bleeding can cause these to become dangerously low.

Tests may include:

  • Sinus x-rays —to identify abnormalities or a mass in the nasal region
  • Endoscopy—using a thin, lighted tube to examine nasal tissues not visible from the front of the nose
  • Blood tests—to check for anemia, low blood platelets, or clotting problems
