Can a Deviated Septum Cause Sleep Apnea?

Introduction: Can a Deviated Septum Cause Sleep Apnea?

Sleep apnea is a common sleep disorder that can have significant impacts on a person’s overall health and well-being. It is characterized by interruptions in breathing during sleep, leading to snoring, gasping, and fragmented sleep patterns. While there are various factors that contribute to sleep apnea, one potential cause that often goes unnoticed is a deviated septum. In this blog post, we will explore whether a deviated septum can indeed cause sleep apnea, its underlying mechanisms, and potential treatment options.

Understanding the Deviated Septum:

The nasal septum is the cartilage and bone structure that separates the two sides of the nasal cavity. Ideally, it should be perfectly straight, allowing for unobstructed airflow. However, in some individuals, the nasal septum becomes deviated, meaning it is crooked or displaced to one side. This condition is often either congenital or the result of trauma or injury.

Effect on Breathing Patterns:

A deviated septum can disrupt the normal functioning of the respiratory system, leading to various symptoms such as nasal congestion, difficulty breathing through the nose, and increased susceptibility to respiratory infections. In some cases, it can also contribute to the onset or exacerbation of sleep apnea.

Connection to Sleep Apnea:

Sleep apnea occurs when the upper airway becomes partially or fully blocked during sleep, causing breathing to temporarily stop. In individuals with a deviated septum, the misalignment of the nasal septum can restrict airflow through the nasal passages. This forces the individual to rely more on mouth breathing, increasing the likelihood of airway collapse during sleep and potentially leading to sleep apnea.

Additionally, a deviated septum might worsen the effects of other risk factors for sleep apnea, such as obesity, which can further narrow the airway passages. This combination of factors can compound the severity of sleep apnea symptoms and their impact on overall health.

Diagnosis and Treatment Options:

If you suspect that your deviated septum may be contributing to your sleep apnea, it is essential to seek medical advice from a qualified healthcare professional. They can evaluate your symptoms, medical history, and perform necessary tests to diagnose both conditions accurately.

Treatment options generally depend on the severity of both the deviated septum and sleep apnea. Initially, conservative measures may be recommended, such as lifestyle changes (e.g., weight management) and the use of nasal dilators or saline sprays to alleviate nasal congestion. However, for more severe cases, surgical intervention might be necessary.

Septoplasty, the most common surgical procedure for deviated septum correction, aims to straighten the nasal septum, improving airflow and reducing nasal obstruction. This can be beneficial not just for nasal breathing but also for addressing sleep apnea symptoms related to a deviated septum.

It is essential to note, though, that while correcting a deviated septum can alleviate some sleep apnea symptoms, it may not be a standalone solution. In cases where sleep apnea persists after septoplasty, further evaluation and treatment options specific to sleep apnea should be explored.


In conclusion, a deviated septum can indeed be a contributing factor to sleep apnea. The misalignment of the nasal septum can impede airflow through the nasal passages, increasing the risk of airway collapse during sleep. If you suspect that your deviated septum may be aggravating your sleep apnea symptoms, consult with a healthcare professional who can provide an accurate diagnosis and recommend appropriate treatment options.

Understanding the connection between sleep apnea and a deviated septum can empower individuals to take proactive steps toward managing their condition effectively. By addressing both the underlying causes and seeking appropriate treatment, individuals can improve their overall sleep quality, enhance their well-being, and lead a more fulfilling life.
