Why does the nasal septum collapse?

The nasal septum can collapse due to various factors, including trauma, chronic nasal congestion, or structural abnormalities. Conditions such as a deviated septum or the weakening of cartilage over time can lead to its collapse. Additionally, severe allergic reactions or the use of certain medications can cause inflammation and contribute to septal collapse. This condition can result in breathing difficulties and may require surgical intervention to correct.
