Ever feel like you just can’t get enough air through your nose, or maybe you’re a noisy nighttime breather? The reason might be simpler than you think – it could be related to the structure inside your nose. Your nasal septum, the thin wall of bone and cartilage dividing your nasal cavity, is meant to sit centered for balanced airflow. But when it’s “deviated,” this wall is off-center, making one nasal passage smaller and often obstructing airflow.

Believe it or not, a deviated septum is incredibly common. Experts estimate that up to 80% of people have some level of nasal septum deviation (according to WebMD and Cleveland Clinic). [1] [2] Many aren’t even aware they have it, especially if the deviation is minor and doesn’t cause noticeable problems day-to-day.

So, how does a deviated septum affect you? When the deviation is significant, it simply makes breathing through your nose harder. This can lead to persistent nasal congestion (often worse on one side), feeling like you can only breathe well through one nostril, or noisy breathing, especially when you lie down to sleep.

Here’s why that matters: Struggling for air through your nose isn’t just annoying; it can seriously mess with your sleep quality. Reduced airflow means less efficient oxygen intake during rest. While it might seem like just a stuffy nose, this kind of disrupted breathing could be a sign of, or contribute to, more significant sleep disorders like obstructive sleep apnea. It’s worth understanding the connection.

Main Causes and Symptoms: Is Your Breathing Problem Nasal or Sleep-Related?

So, you know what a deviated septum is, but why does it happen? And how can you tell if your symptoms point towards a nasal issue like a deviated septum, or something potentially more serious like sleep apnea? Let’s break it down.

1. What Causes a Deviated Septum?

A deviated septum isn’t always something you develop; sometimes, it’s just the way your nose formed. Here are the main reasons why that dividing wall in your nose might be off-center:

• Being Born With It (Congenital): For many people, a deviated septum is simply present from birth. It can occur during fetal development, just a natural variation as the nose takes shape. A WebMD article confirms this is a common cause.

• Injury or Trauma: A blow to the nose is a very frequent culprit. This could happen during contact sports, from a fall, a car accident, or even rough play during childhood. Sometimes, an injury happens early in life, but the breathing problems only become noticeable later on.

• Natural Growth and Aging: Sometimes, the septum can continue to shift or deviate as part of the normal aging process or during growth spurts in adolescence. What might have been a minor deviation can become more pronounced over time.

It’s common for people not to realize they have a deviated septum, or for symptoms to only appear or worsen later in life.

2. Common Signs & Symptoms of a Deviated Septum

If your septum is significantly deviated, you might experience some tell-tale signs related to airflow. Keep an eye out for:

• Nasal congestion or blockage: This is often the most common complaint, and it frequently feels worse on one side. It might feel like you constantly have a stuffy nose that doesn’t clear.

• Difficulty breathing through your nose: You might find it noticeably harder to inhale or exhale through your nasal passages.

• Frequent nosebleeds: The altered airflow can sometimes dry out the nasal lining, making nosebleeds more likely.

• Noisy breathing during sleep: While not necessarily sleep apnea, struggling to get air through a narrowed passage can cause snoring or loud breathing sounds.

• Recurrent sinus infections: Poor drainage due to the blockage can sometimes contribute to sinus issues.

• Preferring to sleep on one side: You might find yourself subconsciously turning to a specific side in bed to breathe more easily through the less obstructed nostril.

3. Key Symptoms of Obstructive Sleep Apnea (OSA)

According to medical studies, Obstructive Sleep Apnea is different – it’s not just about airflow difficulty, it’s about breathing stopping repeatedly during sleep.[3] While a deviated septum can contribute to OSA (according to a Cleveland article), the core symptoms of OSA itself often include:

• Loud, disruptive snoring: Often remarked upon by partners or family members.

• Gasping or choking during sleep: Witnessed episodes where breathing stops, sometimes followed by gasping or choking sounds as breathing restarts. These sleep disturbances are a hallmark sign.

• Excessive daytime sleepiness or fatigue: Feeling exhausted despite spending enough time in bed is a major red flag. Low oxygen levels during sleep impact overall sleep quality.

• Morning headaches: Waking up with headaches regularly.

• Dry mouth or sore throat upon waking.

• Difficulty concentrating or “brain fog” during the day.

• Mood swings, irritability, or depression.

4. Deviated Septum vs. OSA Symptoms: Spotting the Difference

It can be confusing because some symptoms overlap, especially snoring. Here’s a quick comparison:

This table helps show which symptoms point more strongly towards one condition or the other.

5. How to Spot Red Flags

Pay attention to the patterns in your symptoms. Ask yourself:

• Is your difficulty breathing noticeably worse when you lie down?

• Do you snore loudly, and often feel tired or unrefreshed the next day?

• Do you seem to get sinus infections more often than others?

• Are your nasal symptoms (like congestion) predominantly on one side?

If you’re ticking boxes related to both nasal issues and sleep disturbances (like daytime fatigue or reported breathing pauses), it’s a good idea to think about both possibilities. Don’t ignore these signs – consulting with a specialist, like an Ear, Nose, and Throat (ENT) doctor or a sleep medicine physician, is the best way to get a clear diagnosis and discuss treatment options.

Deviated Septum vs. Sleep Apnea: What’s the Real Connection?

It’s a common question: Does having a deviated septum mean you’ll automatically develop sleep apnea? Many people assume there’s a direct cause-and-effect link, but the relationship is more nuanced. Let’s clear things up:

A deviated septum is not a direct cause of sleep apnea, but it can certainly worsen existing symptoms or make underlying obstructive sleep apnea (OSA) more apparent.

Think of it this way: a deviated septum primarily causes nasal obstruction, making it harder to breathe through your nose. Obstructive sleep apnea, on the other hand, is about the airway collapsing or becoming blocked further down in your throat during sleep. While distinct, these issues can influence each other.

What the Science Says

Research paints a picture of correlation, not direct causation, when looking at deviated septum and sleep apnea:

• Mayo Clinic points out that while conditions like a deviated septum can block airflow through your nose, they aren’t typically considered the sole cause of OSA.[4]  The primary issue in OSA is the throat airway collapse.

• WebMD echoes this, suggesting that while a deviated septum might not cause OSA on its own, the resulting nasal obstruction can amplify symptoms, especially if you also deal with issues like allergies that further compromise breathing.

• A compelling 9-year study published in PMC (PubMed Central) found a significant link: individuals diagnosed with a deviated septum had a notably higher likelihood, 4.39 times higher, of subsequently being diagnosed with OSA compared to those without a deviated septum. 

It’s crucial to understand this is a strong correlation, indicating a relationship or shared risk factor, but it doesn’t prove the deviated septum caused the sleep apnea in those individuals.

Sleep Apnea: Often More Than One Cause

Obstructive Sleep Apnea is typically a multifactorial condition. This means several factors often combine to create the problem. A deviated septum causing nasal obstruction can be one piece of this puzzle, but it rarely acts alone. Other common contributors include:

• Other Structural Issues: Enlarged tonsils or adenoids, a large tongue, a thick neck circumference, or specific jaw alignments.

• Obesity: Excess weight, particularly around the neck, is a major risk factor.

• Genetics: Family history can play a role.

• Aging: Muscle tone in the airway can decrease with age.

• Neuromuscular Control: Issues with how the brain signals the airway muscles.

• Lifestyle Habits: Alcohol consumption (especially near bedtime), smoking, and sleeping position (back-sleeping often worsens OSA).

A deviated septum contributes to increasing airflow resistance in the upper airway. This added strain can make throat collapse more likely in susceptible individuals or make existing OSA worse. It can also make treatments like CPAP harder to use comfortably, affecting CPAP compliance.

Why Understanding the Difference Matters

Misunderstanding the link between a deviated septum and OSA can lead to problems:

• Delayed Diagnosis: Someone might undergo surgery to fix their septum, thinking it will “cure” their sleep issues, without realizing they have underlying OSA that still needs diagnosis and treatment (like CPAP). Their nasal obstruction might improve, but the dangerous breathing pauses during sleep could continue.

• Reduced Treatment Effectiveness: If you have OSA and use CPAP, untreated significant nasal obstruction from a deviated septum can make it difficult to tolerate the pressure or get a good mask seal, reducing CPAP compliance and effectiveness.

• Incomplete Symptom Relief: Addressing only the septum or only the sleep apnea might not fully resolve symptoms like fatigue or poor sleep if both conditions are contributing.

It’s essential to consider both possibilities. If you suspect you have issues with nasal breathing and symptoms of sleep apnea, consulting with both an Ear, Nose, and Throat (ENT) specialist and a sleep medicine doctor can ensure all contributing factors to your OSA risk are properly evaluated and managed.

How It Affects CPAP Users and Snorers (And What You Can Do)

If you snore loudly or use a CPAP machine for sleep apnea, a deviated septum can throw a significant wrench into the works. That structural issue in your nose doesn’t just affect daytime breathing; it can complicate your nights.

1. The Challenge for CPAP Users

Continuous Positive Airway Pressure (CPAP) therapy works by sending pressurized air through your airway to keep it open while you sleep. For this to work effectively, especially with nasal masks or nasal pillow masks, the air needs a clear path through your nose.

A deviated septum causes nasal obstruction, acting like a roadblock for that pressurized air. This can lead to several problems:

• Discomfort and Leaks: The machine might need higher pressure settings to get past the blockage, which can feel uncomfortable or cause mask leaks.

• Reduced CPAP Compliance: When therapy is uncomfortable or feels ineffective due to poor airflow, people are much less likely to stick with it. Many end up abandoning their CPAP therapy altogether out of frustration.

• Lower CPAP Adherence: Studies, like the large 9-year cohort PMC study, suggest that nasal issues contributing to airway resistance are linked with difficulties in managing sleep apnea, which logically extends to challenges with treatment adherence.

Did You Know? 

Fixing Nasal Obstruction May Boost CPAP Success. While surgery for a deviated septum (septoplasty) isn’t a cure for sleep apnea itself, sources by the Mayo Clinic and another by the Cleveland Clinic also note that it can significantly improve nasal breathing. 

For CPAP users, this often translates to greater comfort, potentially lower pressure needs, and better CPAP compliance because the therapy becomes easier to tolerate.

2. The Link to Mouth Breathing and Snoring

When your nose is blocked, your body naturally switches to mouth breathing. While this gets air in, it often comes with downsides, especially during sleep:

• Increased Snoring: Forcing air through the mouth and throat increases the vibration of soft tissues (like the palate and uvula), leading to louder and more frequent snoring. A study published on ScienceDirect highlights how restricted nasal airflow contributes to these vibrations.[5] This isn’t just noise; severe snoring can be a key indicator of underlying sleep apnea.

• Dry Mouth: Waking up feeling parched is a common side effect of mouth breathing all night.

• Poorer Sleep Quality: Both for the person struggling to breathe and their bed partner, disturbed by the snoring noise.

3. Consequences for Sleep Quality

Even if you diligently use your CPAP, significant nasal obstruction can still undermine your sleep quality. 

If the air pressure isn’t delivered smoothly or if leaks constantly wake you up, you might not be getting the restorative deep sleep and REM sleep you need. This can disrupt sleep cycles, disturb your partner, and lead to persistent daytime fatigue, even when you think you’re treating your sleep apnea. Inconsistent therapy due to discomfort means inconsistent results.

4. Practical Tips to Manage the Challenges

If you suspect a deviated septum is interfering with your sleep or CPAP use, here are some actionable steps you can try while you work towards a long-term solution:

• Consider Your Mask Style: If you use a nasal or nasal pillow mask, try switching to a full-face CPAP mask. This delivers air to both your nose and mouth, potentially bypassing some of the nasal obstruction.

• Open Nasal Passages: Over-the-counter external nasal strips or internal nasal dilators can temporarily widen nasal passages to improve airflow during sleep.

• Optimize Sleeping Position: Sleeping on your side often reduces airway collapse compared to sleeping on your back. Using a specialized CPAP pillow can also help maintain the mask seal and comfort in different positions.

• Practice Good Nasal Hygiene: Regularly using saline sprays or a neti pot can help clear mucus and reduce inflammation. Using a humidifier in your bedroom, especially one connected to your CPAP machine, can prevent your nasal passages from drying out.

• Consult the Experts: If these tips don’t provide enough relief, don’t hesitate! Talk to your sleep doctor or an Ear, Nose, and Throat (ENT) specialist. They can properly assess your septum and discuss whether treatments like septoplasty could improve your breathing and CPAP compliance.

Don’t give up on your CPAP therapy! While a deviated septum can add a layer of difficulty, adjustments and addressing the underlying nasal obstruction can make a huge difference. Relief is often possible with the right combination of strategies.

Treatment Options: From Meds to Surgery (and When to Consider Each)

Dealing with a deviated septum isn’t a one-size-fits-all situation. The best approach for you really depends on how severe your symptoms are and how much they’re impacting your daily life and sleep quality. Generally, treatments fall into two main camps: non-surgical options that help manage symptoms, and surgery to correct the underlying structural issue.

1. Non-Surgical Options (Mild to Moderate Symptoms)

If your deviated septum causes mild or occasional issues, or if surgery isn’t desired or necessary, several options can help you breathe easier by managing the symptoms:

• Decongestants: Available as oral pills or nasal sprays, these can temporarily shrink swollen nasal tissues, providing quick relief from congestion. However, Nasal decongestant sprays shouldn’t be used for more than a few days, as long-term use can cause “rebound congestion,” making stuffiness worse.

• Antihistamines: If allergies are making your nasal congestion worse, antihistamines (pills or sprays) can help calm the allergic reaction and reduce stuffiness.

• Nasal Steroid Sprays: These prescription or over-the-counter sprays reduce inflammation in the nasal passages. They don’t work instantly (often taking 1-3 weeks for full effect) but can provide significant ongoing relief when used consistently.

• Nasal Strips or External Dilators: These adhesive strips worn across the bridge of the nose (or small dilators placed inside the nostrils) gently pull the nasal passages open, improving airflow. They’re drug-free and can be helpful for nighttime breathing or snoring.

• Saline Irrigation (e.g., neti pot): Using a saline spray or a neti pot to rinse your nasal passages helps clear out mucus, allergens, and irritants, keeping things moist and less inflamed.

• Lifestyle Adjustments: Simple changes like using a humidifier in your bedroom (especially during dry seasons or if you use heating/AC) and optimizing your sleeping position (side sleeping is often better than back sleeping) can also offer some relief.

Important Note: These methods primarily treat the symptoms (like congestion or inflammation) caused by a deviated septum. They don’t fix the actual crookedness of the septum itself. They are often best suited for people with mild deviations or infrequent symptoms.

2. Surgical Option: Septoplasty

When Is Surgery Necessary?

For significant, persistent symptoms that disrupt breathing and quality of life, surgery might be the best option. The procedure to correct a deviated septum is called septoplasty.

During septoplasty, a surgeon works through the nostrils (no external cuts are usually needed) to straighten the septum by trimming, repositioning, or removing parts of the bone and cartilage. This is the only way to correct the deviated structure physically.

• Who is Septoplasty For?

• Individuals with moderate to severe septal deviation causing significant nasal blockage.

• CPAP users who struggle with mask comfort, seal, or airflow due to nasal obstruction.

• People experiencing chronic sinus infections, frequent nosebleeds, or sleep disturbances are directly related to their deviated septum.

• Pros:

• It offers a permanent fix for the structural problem.

• It can dramatically improve nasal airflow and make breathing easier.

• It may reduce snoring and significantly improve CPAP adherence and comfort by creating a clearer path for the air. A PubMed study suggests septoplasty can improve nasal function in OSA patients, sometimes helping reduce symptoms or making CPAP therapy much easier to tolerate.[6]

• Cons:

• It’s an outpatient surgery, but it does involve a recovery period (usually a week or two of swelling/stuffiness).

• Like any surgery, there are small risks, such as bleeding, infection, or very rarely, changes to the external shape of the nose or numbness.

Comparison of Treatment Options

Here’s a quick overview to help compare the different approaches:

When to Talk to Your Doctor

Consider scheduling a consultation with an Ear, Nose, and Throat (ENT) specialist or your sleep doctor if you:

• Struggle to use your CPAP comfortably because of a blocked nose.

• Experience frequent nosebleeds or chronic sinus infections.

• Notice persistent nasal congestion, especially if it’s worse on one side and doesn’t improve with basic remedies.

• Are tired of just managing symptoms and want to explore long-term solutions for better breathing.

Deciding on treatment involves weighing the severity of your symptoms against the pros and cons of each option. A specialist can help you determine the best path forward for your situation.

Home Sleep Test for Diagnosing Sleep Apnea at Home

After learning about deviated septums and sleep apnea, you might be asking yourself, 

“Could I actually have sleep apnea?” 

If concerns about snoring, fatigue, or breathing interruptions are on your mind, finding answers doesn’t have to mean spending a night tangled in wires at a sleep lab. There’s a much simpler, more comfortable way to get clarity right from your own bed.

Introducing Sleeplay’s Home Sleep Test (HST)

A Home Sleep Test, like the FDA-cleared NightOwl device offered by Sleeplay, is designed to screen for Obstructive Sleep Apnea (OSA) conveniently and accurately at home. In simple terms, it involves wearing a small, easy-to-use sensor (usually on your finger) while you sleep for a few nights.

This clever little device gathers important data about your sleep, including:

The test typically involves wearing the sensor for about three nights to capture reliable data. A board-certified sleep physician then reviews the results to provide a diagnosis if applicable.

What Does the Home Sleep Test Detect?

It’s essential to be clear: a Home Sleep Test is specifically designed to diagnose Obstructive Sleep Apnea (OSA). It won’t tell you if you have a deviated septum – that requires an examination by an ENT specialist or other medical professional.

However, if a deviated septum is contributing to or worsening sleep apnea symptoms, the HST is a crucial tool for identifying and diagnosing the OSA itself. Knowing if you have OSA is the first step toward getting the proper treatment, whether that involves CPAP therapy, lifestyle changes, or addressing contributing factors like nasal obstruction.

Home Sleep Test vs. In-Lab Sleep Study

Why choose a Home Sleep Test? Here are a few key advantages compared to traditional in-lab polysomnography (PSG):

• Cost: HSTs are generally significantly more affordable than in-lab studies.

• Comfort & Convenience: You get to sleep in your own bed, in your normal environment, making the results more reflective of a typical night’s sleep.

• Wait Times: Scheduling an HST and getting results is often much faster than waiting for an appointment at a busy sleep lab.

• Accessibility: No need to travel, arrange overnight stays, or take extra time off work. The test kit is delivered to you.

The Simple Process

Getting tested at home is straightforward:

1. Receive Device & App: You’ll get the small NightOwl sensor and instructions on how to download a companion app on your smartphone.

2. Wear the Sensor: Simply wear the sensor on your finger as instructed for the specified number of nights (usually three).

3. Get Your Results: Data is typically transmitted automatically via the app. Once reviewed by a sleep physician, you’ll receive a detailed report and diagnosis if applicable.

Snoring Solutions and Lifestyle Tips That Can Help

Heard complaints about your nightly noise levels? While loud or persistent snoring can be linked to conditions like sleep apnea (especially if paired with fatigue or gasping), not all snoring signals a serious health issue. Sometimes, it’s just simple snoring!

If you’re looking for manageable, affordable ways to quiet things down, this section offers some “first step” strategies you can try right at home.

Understanding Your Snoring Type

Knowing why you snore can help you find the right solution. Here’s a quick guide:

Anti-Snoring Tools Worth Trying

Based on the likely cause of your snoring, here are some popular tools and devices:

• Nasal Solutions (For Nasal Blockage/Snoring):
  

• Nasal Strips/Dilators: External nasal strips or internal dilators physically open the nasal passages. The NozeSeal Strapless CPAP solution can also help if sleep apnea is diagnosed.

• Bongo Rx: A prescription EPAP (Expiratory Positive Airway Pressure) device using small nasal inserts to create pressure that keeps the airway open.

• Saline Rinses/Sprays: Help clear congestion and reduce inflammation naturally.

• Mouth Solutions (For Mouth Breathing/Snoring):
  

• Mouth Tape: Gentle adhesive strips (like Hush Mouth Tape or CPAPhero tape) encourage nasal breathing by keeping the lips sealed. A study published on ScienceDirect suggests that preventing mouth breathing can reduce airway collapse and snoring.

• Oral Appliances (MADs): Custom-fitted or boil-and-bite devices (like myTAP or SmartGuard) worn in the mouth to move the lower jaw slightly forward, preventing the tongue from blocking the airway.

• Positional Aids (For Back-Snoring):
  

• Positional Trainers: Wearable devices (like the CPAPology Sleep Noodle bumper belt) make back-sleeping uncomfortable and encourage you to stay on your side.

• Smart Nora: A contact-free system with a pillow insert that gently moves your head when it detects snoring sounds, stimulating airway muscles without fully waking you. Positional therapy is often effective as gravity has less effect on the airway when side-sleeping (this is also supported by the ScienceDirect study).

Lifestyle Adjustments for Quieter Nights

Don’t underestimate the power of simple habits! These low-cost, sustainable changes can significantly reduce snoring risk:

• Sleep on Your Side: Gravity is less likely to cause your tongue or throat tissues to collapse into your airway.

• Maintain a Healthy Weight: Excess weight, especially around the neck, can narrow the airway.

• Avoid Alcohol and Sedatives Before Bed: These relax throat muscles, making airway collapse and snoring more likely.

• Use a Humidifier: Keeping bedroom air moist can reduce nasal and throat irritation and congestion.

• Manage Allergies: Treat allergies effectively with antihistamines, nasal steroid sprays (as discussed previously), or by reducing allergens in your bedroom (HEPA filters, dust mite covers).

• Quit Smoking: Smoking irritates and inflames airway tissues, contributing to snoring and sleep apnea.

Top 5 Tips to Try Tonight for Better Breathing

1. Try sleeping on your side (use pillows for support).

2. Rinse your nose with saline before bed.

3. Consider an over-the-counter nasal strip.

4. Skip alcohol within 3-4 hours of bedtime.

5. Elevate your head slightly with an extra pillow (if comfortable).

Still Snoring Despite Trying Everything?

It might be time to test for sleep apnea!

If you’ve given these tips and tools a fair shot and the snoring persists, especially if it’s loud, disruptive, or accompanied by daytime fatigue, it might be more than just simple snoring. It could be a sign of underlying obstructive sleep apnea.

Don’t ignore persistent symptoms. It might be time to consider getting tested.

FAQs

What is a deviated septum? 

A deviated septum means the thin wall (septum) made of bone and cartilage that divides your two nasal passages is off-center or crooked. This makes one nasal passage smaller than the other, which can obstruct airflow and make breathing through your nose more difficult.

Can a deviated septum cause sleep apnea? 

While a deviated septum doesn’t directly cause obstructive sleep apnea (OSA), it can definitely make it worse or bring underlying OSA to light. The nasal obstruction increases the effort needed to breathe, which can contribute to airway collapse further down in the throat, especially during sleep.

Are a deviated septum and sleep apnea related? 

Yes, there’s a known connection. Studies show people with a deviated septum have a significantly higher risk of also having or developing obstructive sleep apnea. The deviated septum contributes to nasal obstruction, which can worsen OSA symptoms or make treatments like CPAP harder to use effectively.

How common is a deviated septum? 

It’s incredibly common! Experts estimate that up to 80% of people have some degree of septal deviation, though many don’t experience severe symptoms or might not even know they have it unless it causes noticeable breathing problems.

Should I worry about a deviated septum and sleep? 

You should pay attention if you have symptoms. A minor deviation might not affect your sleep at all. However, if your deviated septum causes significant nasal congestion, difficulty breathing, loud snoring, or forces you into mouth breathing at night, it can certainly disrupt your sleep quality and could be worsening conditions like sleep apnea. It’s worth discussing with a doctor if you have concerns.

What are the symptoms of a deviated septum? 

Common symptoms include persistent nasal congestion (often worse on one side), difficulty breathing through your nose, frequent nosebleeds, noisy breathing during sleep (including snoring), recurrent sinus infections, and sometimes facial pain or pressure. You might also find yourself preferring to sleep on one particular side to breathe more easily.

What are the symptoms of sleep apnea? 

Hallmark symptoms of obstructive sleep apnea include loud, disruptive snoring, witnessed pauses in breathing during sleep (apneas), gasping or choking sounds during sleep, excessive daytime sleepiness or fatigue despite adequate hours in bed, morning headaches, dry mouth upon waking, difficulty concentrating, and mood changes like irritability.

How can I tell if my breathing problems are from my nose or sleep? 

It can be tricky as symptoms overlap (like snoring). Generally, problems primarily from a deviated septum involve nasal congestion, difficulty inhaling through the nose, and maybe nosebleeds. Sleep apnea symptoms center more around events during sleep (breathing pauses, gasping) and the consequences after sleep (severe daytime fatigue). If you experience symptoms from both categories, it’s best to consult a doctor.

Do I have a deviated septum? 

While symptoms like chronic one-sided nasal blockage strongly suggest it, you can’t diagnose a deviated septum yourself. An Ear, Nose, and Throat (ENT) specialist can diagnose it definitively through a physical examination, sometimes using a small camera (endoscope) to look inside your nose.

Is loud snoring a sign of a deviated septum or sleep apnea? 

A deviated septum can cause loud snoring due to turbulent airflow through a narrowed passage. However, it’s also a primary symptom of sleep apnea, often accompanied by breathing pauses and daytime fatigue. If snoring is loud and persistent, it warrants investigation for both possibilities.

How does a deviated septum affect CPAP therapy? 

A deviated septum can make CPAP therapy more challenging. The nasal obstruction can block the flow of pressurized air, requiring higher machine settings, which may lead to discomfort, mask leaks (especially with nasal masks), and ultimately make it harder for users to stick with their therapy (lower compliance).

Can a deviated septum make my CPAP mask leak? 

Yes, it can. If the CPAP pressure needs to be turned up high to get past the nasal blockage caused by the deviated septum, that force can make it more difficult to maintain a proper seal with your mask, leading to air leaks, especially with nasal or nasal pillow styles.

What kind of CPAP mask is best if I have a deviated septum? 

Many people with significant nasal obstruction from a deviated septum find a full-face mask more comfortable and effective. Because it covers both the nose and mouth, it can deliver the therapy air even if nasal breathing is difficult. However, personal preference varies, so discuss options with your sleep specialist or CPAP provider.

Can fixing my deviated septum help my CPAP? 

Absolutely. Undergoing septoplasty (surgery to straighten the septum) can significantly improve nasal airflow. For CPAP users, this often means they can use lower, more comfortable pressure settings, experience fewer mask leaks, and find it much easier to tolerate and stick with their therapy long-term. It doesn’t cure the OSA, but it optimizes the CPAP treatment.

Why does my nose feel blocked with my CPAP? 

There could be a few reasons. The deviated septum itself might be physically blocking the airflow. The constant air pressure, especially if high, can sometimes cause nasal tissues to swell slightly (congestion). Also, the airflow can be drying, leading to irritation and congestion – using the CPAP humidifier is essential to help prevent this.

How is a deviated septum treated? 

Treatment depends on symptom severity. For mild issues, managing symptoms with medications like nasal steroid sprays (for inflammation), decongestants (short-term use only), or antihistamines (if allergies contribute) might be enough. Saline rinses and nasal strips can also help. The only way to correct the underlying structural problem is through surgery (septoplasty).

Can surgery fix a deviated septum? 

Yes, septoplasty is a surgical procedure specifically designed to correct a deviated septum. The surgeon straightens the wall between your nasal passages, providing a permanent solution to the structural blockage.

Are there medications for a deviated septum? 

There are no medications that can physically straighten a deviated septum. However, medications like nasal steroid sprays, decongestants, and antihistamines can effectively treat the symptoms associated with it, such as nasal congestion, swelling, and inflammation, making breathing easier.

Can a home sleep apnea test detect sleep apnea caused by a deviated septum? 

A home sleep test (HST) is designed to detect and diagnose Obstructive Sleep Apnea (OSA). It measures breathing patterns, oxygen levels, and respiratory effort to identify apnea events. While it won’t diagnose the deviated septum itself, it will accurately determine if you have OSA, which may be influenced or worsened by your deviated septum.

What are the best snoring solutions if I have a deviated septum? 

If your snoring is primarily due to nasal blockage from the deviated septum, nasal strips or dilators can help open passages temporarily. Saline rinses and managing any allergies are also beneficial. If you resort to mouth breathing, mouth tape might help encourage nasal breathing (if possible). For severe, persistent nasal obstruction causing snoring, septoplasty surgery might be the most effective long-term solution to improve nasal airflow. Lifestyle changes like side-sleeping and avoiding alcohol before bed are always good supporting strategies.
