Deviated Septum

A deviated septum occurs when the thin wall between your nasal passages is significantly off-center or crooked, which can affect airflow. This condition may contribute to breathing difficulties, sinus infections, or other issues. Many people have some degree of deviation, which can vary in severity and impact.

  • What exactly is a deviated septum?

    A deviated septum is when the wall that divides your nose into two halves is shifted to one side instead of being straight down the middle. This can make one side of your nose narrower than the other.

    A deviated septum can block airflow through your nose, making it harder to breathe, especially on the side that's narrower. This can be worse when you have a cold or allergies that cause swelling.

  • Can a deviated septum cause other health problems?

    A deviated septum mainly affects breathing and comfort, but it can also make it harder to sleep well. In some cases, it may contribute to sinus problems or make allergy symptoms worse.

  • Why do some people get a deviated septum and others don't?
    MedlinePlusMay 2026

    Some people are born with a deviated septum, while others develop one from an injury to the nose, like from a fall or sports accident. It's just how some noses naturally form.

  • Is there anything I can do to prevent symptoms from getting worse?

    You can help manage symptoms by avoiding things that irritate your nose, staying hydrated, using a humidifier, and treating allergies if you have them. Keeping your head elevated when sleeping may also help with breathing.
