Close look on a posterior nosebleed

A posterior nosebleed occurs if there is damage to the tissues at the rear part of the nose in the nasal cavity. Remember that this form of nosebleed can be severe. It can be brought about by injuries to the nose but also due to high blood pressure or even other health ailments.

An individual is likely to have a posterior nosebleed if bleeding lasts longer than 20 minutes or occurs after an injury to the head, face or nose. It is prevalent among children between 2-10 years and adults between 50-80 years old.

What are the causes?

A posterior nosebleed often has external or environmental causes such as:

  • Picking on or scratching the nose extensively
  • Blowing the nose too hard or frequently
  • Breathing in tobacco smoke including secondhand smoke
  • Dry, warm weather which makes the skin prone to bleeding

    Apply an ice pack over the nose to alleviate the swelling and pain.

  • Inhaling chemicals in the workplace such as ammonia or gasoline
  • Injuries that damages parts of the nose or skull

In some cases, a nosebleed occurs after using inflammation drugs or blood thinners. Some medical ailments are also known causes such as:

  • Allergies or common cold
  • Deviated septum
  • Tumors in or around the nose
  • Ailments that affect the ability to form clots or affect the blood vessels such as high blood pressure or hemophilia
  • Complications after a recent nasal surgery

Management of a posterior nosebleed

If blood flows from the front of the nose, the individual should sit up and lean forward to ensure that the blood will not drain down the throat. Squeeze the front part of the nose utilizing your thumb and finger with a tissue or clean cloth to control the bleeding.

Continue to pinch the nose for 10-15 minutes up until the bleeding halts. Apply an ice pack over the nose to alleviate the swelling and pain.
