Ideally, the nasal septum will devide the nasal cavity equally, but it is common for this partition to be slightly off center. a deviated septum, however, is a condition in which the nasal septum is shifted significantly away from the midline. explain how this abnormality may cause difficulty in breathing.

A deviated septum occurs when bone and the cartilage that divides the nose septum become off-center which results in two unequal nasal septum. This makes one nasal chamber smaller and another larger.

This abnormality causes difficulty in breathing because of the congestion and blockage of the smaller nasal cavity. Due to this congestion airflow in the lungs is hindered which results in lack of oxygen and difficulty in breathing.

Apart from difficulty in breathing it can leads to nose bleeding, loud snoring during sleep, facial pain, headache, and in respiratory infections breathing become more difficult.

A deviated septum can develop due to some trauma or during surgery but some people are born with this abnormality.
