A simple deviation of the nasal septum generally does not cause people to faint.

Common clinical symptoms of a deviated nasal septum include repeated nasal congestion, runny nose, and nosebleeds. Some patients may experience headaches, dizziness, and snoring during sleep, but generally, consciousness remains clear without episodes of fainting.

If fainting occurs, it is necessary to investigate other potential issues, such as fluctuations in blood pressure, low blood sugar, or problems related to blood vessels or nerves in the head. It is generally advised to first consult with a neurology department to investigate the specific causes of the fainting. If the deviation of the nasal septum is severe, considering surgery might be an option.
