Nasal Airway Obstruction: Why You Can't Breathe Through Your Nose

Do you feel blocked up all the time? Maybe you breathe through your mouth at night, wake up tired, or run out of air on a short walk, even when you are not sick. If that sounds like you, the good news is that you are not stuck with it.
A cold or an allergy flare can block your nose for a week or two, then clear up. But when the block lasts for weeks or months, and a nasal spray doesn't help, the cause is often the shape of your sinuses or nasal valve.
That problem is called nasal airway obstruction, and it needs a different fix than what you can get at the drugstore.
Chesapeake Bay ENT helps patients with a blocked nose across Hampton Roads.

Nasal Obstruction vs. Nasal Congestion

Congestion and obstruction can feel the same, and most people call both a stuffy nose. But they are not the same thing, and the difference matters for how you get better.
Nasal congestion comes from swelling or mucus in the nasal cavity, usually from a cold, the flu, or allergies. It tends to come and go, and it often clears on its own or with a nasal spray.
Nasal airway obstruction is a real blockage inside the nose that doesn't go away. A nasal spray or an allergy pill will not fix it, because they cannot change the shape of your airway. If your stuffy nose has lasted a long time, you may have chronic nasal congestion or true nasal obstruction, and an ENT can tell you which one you have.

A quick airway check

Here is a quick nasal obstruction test you can do right now.
Put two fingers on each cheek next to your nose. Then press and pull out to the sides and breathe in. If that makes it easier to breathe, a part of your nose called the nasal valve may be the problem.
This test is called the Cottle maneuver, and an ENT exam can confirm your diagnosis.

What Causes Obstructed Nasal Airways?

A few things can block airflow and cause obstructed nasal airways. Most cases come from one of these:

Nasal valve collapse

The nasal valve is the narrowest part of the nose, and if it is weak, it caves in when you breathe in. This is the most common cause, and it is often missed. VivAer is designed to fix it.

A deviated septum

The wall between your nostrils leans to one side, which makes that side harder to breathe through.

Enlarged turbinates

These small ridges inside the nose can swell and stay swollen, crowding the nasal cavity and reducing airflow.

Nasal polyps

These are soft growths that come from long-term swelling and block the nose.

Allergies and sinus infections

Ongoing allergies or repeated sinus infections keep the nose swollen, and over time that swelling can act like a block.

If your block doesn’t go away with nasal sprays or other over-the-counter treatments, you may have chronic nasal obstruction. An exam finds the cause, so you get the right fix.

Nasal Obstruction Symptoms

Nasal obstruction symptoms are more than a stuffy nose. Most people notice:
  • A blocked nose that nasal spray doesn't fix
  • Mouth breathing at night or during exercise, especially
  • Snoring or poor sleep
  • Fatigue
  • One-sided nasal breathing
When your nose is blocked, you breathe through your mouth to get air, which dries out your mouth and throat and can make you snore. It can also wake you up repeatedly, so you never feel rested. A nasal spray may help for an hour, but it cannot open a nose that is too narrow.

A Minimally Invasive Treatment Option

You do not always need surgery to fix a blocked nose.
For a weak nasal valve, a minimally invasive option called VivAer may help.
It's done in the office in about 15 minutes, with no cutting, and you go home the same day. Most people get back to their normal day right away.

Nasal Obstruction Treatment

The best nasal obstruction treatment depends on the cause, so care starts with an exam.
For a stuffy nose from allergies, a nasal congestion treatment like an allergy pill, a nasal spray, or allergy shots can help. These ease swelling, but they don't fix a blockage caused by your nose's shape. If you have looked for a stuffy nose treatment for months with no luck, the cause may be your anatomy, not allergies.
For a weak nasal valve, VivAer Nasal Airway Remodeling opens the airway in the office without surgery, and in studies, 96% of patients said their breathing improved. Enlarged turbinates can be treated with turbinate reduction, and a badly deviated septum can be fixed with a small surgery called septoplasty.
An ENT will help you pick the right path.

When to See an ENT

Most short stuffy noses clear up on their own. See an ENT if your blocked nose lasts more than a few weeks, or if a nasal spray, allergy pill, or decongestant doesn't help. It is also worth a visit if the block keeps you up at night or wears you out during the day. Watch for warning signs too, such as one side that stays blocked, a block that worsens, or a stuffy nose with facial pain, nosebleeds, or a reduced sense of smell.
At Chesapeake Bay ENT, your first visit includes a nasal exam to find the cause, so your care fits the real problem instead of a guess.

When to See an ENT

What is the difference between nasal congestion and nasal obstruction?

Nasal congestion is usually temporary, caused by a cold, the flu, or allergies, and it often clears with medication. Nasal airway obstruction is a structural issue that restricts airflow whether or not you are sick. It is chronic and persistent, and it usually needs specialist evaluation and treatment rather than over-the-counter remedies.

Can nasal airway obstruction be treated without surgery?

Yes. In many cases, the Vivaer treatment addresses the structural cause in the office in under 15 minutes, with no incisions, no tissue removal, and a same-day return to activity. Many patients notice a difference soon after, and full results build over a few weeks. Some other cases may need a different treatment method.

How do I know if my blocked nose is structural or just congestion?

A self-test called the Cottle maneuver can help. Place two fingertips on your cheeks on either side of your nose and pull outward. If your breathing gets easier, nasal valve obstruction may be contributing. An ENT evaluation gives you a definitive answer.

When should I see a doctor for a blocked nose?

See an ENT when nasal blockage has lasted more than a few weeks, has not responded to over-the-counter medication, or is affecting your sleep, energy, or daily quality of life.
