Understanding Deviated Septum: Symptoms and Causes

Apr 19, 2025

Deviated Septum: Symptoms & Causes

Overview

  • A deviated septum occurs when the nasal septum, the thin wall between the nasal passages, is off to one side.
  • It causes one nasal air passage to be smaller, possibly blocking a side of the nose.
  • This can reduce airflow, making breathing difficult and sometimes make the nose appear crooked.
  • Treatments include medication for swelling and surgery to correct the septum.

Symptoms

  • Many have no symptoms and may not realize they have a deviated septum.
  • Possible symptoms include:
    • Blockage in one or both nostrils, worsened by colds or allergies.
    • Nosebleeds due to dryness in the nasal septum.
    • Noisy breathing during sleep.
    • Sleeping on one side to ease nighttime breathing.

When to See a Doctor

  • Consult a healthcare professional if:
    • A blocked nostril does not clear up with treatment.
    • Frequent nosebleeds occur.

Causes

  • Causes include:
    • Condition at birth: Present during fetal development or seen at birth.
    • Injury to the nose: Can result from childbirth, contact sports, rough play, or car accidents.
    • Aging can worsen a deviated septum over time.
    • Swelling/irritation from infections can lead to nasal blockage.

Risk Factors

  • Risk factors include:
    • Playing contact sports.
    • Not wearing a seat belt in vehicles.

Complications

  • Complications from a severely deviated septum include:
    • Dry mouth from mouth breathing.
    • Disturbed sleep due to nasal breathing difficulty.
    • Repeated nosebleeds from nasal septum dryness.

Prevention

  • To prevent nose injuries:
    • Wear a helmet/midface mask in contact sports.
    • Use a seat belt when in a vehicle.
