Distinguishing between nasal polyps and simple rhinitis can be challenging because both conditions involve nasal congestion and discharge. However, while rhinitis is a general inflammation of the nasal lining, nasal polyps are actual physical growths that develop as a result of that inflammation. In the UK, many people mistake polyps for a stubborn cold or hay fever, but there are specific red flag symptoms that point toward a structural blockage rather than just surface swelling.
The most significant indicator of nasal polyps is the persistence and nature of the blockage. While rhinitis symptoms often fluctuate based on allergen exposure or time of day, polyps create a more constant and immovable obstruction. Understanding these subtle clinical differences is essential for ensuring you receive the correct treatment, such as steroid drops or surgery, rather than just antihistamines. A progressive loss of the sense of smell is often the defining symptom that leads to a diagnosis of polyps in the UK.

Persistent loss of smell and taste
One of the clearest signs that you may have nasal polyps rather than simple rhinitis is a significant and long lasting reduction in your sense of smell. In rhinitis, your smell might be dulled because of mucus, but it usually returns once the nose is cleared. Because polyps physically grow in the upper reaches of the nasal cavity, they can block scent molecules from ever reaching the olfactory nerves.
This often leads to a secondary loss of taste, as flavour perception is heavily reliant on the sense of smell. Many UK patients with polyps report that food has become bland or that they can only detect basic sensations like saltiness or sweetness. If your sense of smell has been missing for weeks or months despite using standard nasal sprays, it is a strong indication that a physical growth may be present.
The nature of the nasal blockage
The type of congestion experienced with nasal polyps is often described as feeling like a solid, permanent mass inside the nose. In allergic or non allergic rhinitis, the blockage usually shifts from one nostril to the other or improves after a hot shower or exercise. Polyps do not shrink or shift easily, meaning the blockage feels the same regardless of your activity level or environment.
Secondary signs and facial pressure
Because nasal polyps often block the drainage ports of the sinuses, they lead to symptoms that mirror chronic sinusitis. This includes a dull, aching pressure across the forehead and cheeks. Unlike the sharp pain of an acute infection, the pressure from polyps is often a constant, low level discomfort that persists for months.
Other symptoms that suggest polyps over simple rhinitis include:
- Frequent nosebleeds: Caused by the polyp tissue being more fragile than the normal nasal lining.
- Post nasal drip: A constant sensation of thick mucus at the back of the throat.
- Aching in the upper teeth: Caused by pressure in the maxillary sinuses.
- Changes in voice: A nasal or muffled quality to the speech because of the lack of airflow.
Comparison: Symptoms of Rhinitis vs Nasal Polyps
| Feature | Simple Rhinitis | Nasal Polyps |
| Itching and Sneezing | Very common | Rare |
| Loss of Smell | Temporary or mild | Often severe and persistent |
| Blockage Type | Fluctuating and shifting | Solid and permanent |
| Response to Antihistamines | Usually good | No effect |
| Facial Pressure | Occasional | Chronic and heavy |
| Snoring | Possible | Very common |
| Discharge Colour | Clear or cloudy | Often thick and discoloured |
To Summarise
Nasal polyps are distinguished from simple rhinitis by the permanence of the blockage and the significant impact on the sense of smell. While rhinitis causes itchy, fluctuating congestion, polyps create a solid physical barrier that does not respond to standard allergy treatments. Recognising these signs early, especially a loss of smell and chronic facial pressure, is vital for UK patients to move beyond home care and access more advanced treatments. If your nasal symptoms have become a constant part of your life, it is likely that more than just surface inflammation is involved.
If you notice a visible fleshy growth in your nostril, experience a complete blockage on only one side, or have persistent nosebleeds, book an appointment with your GP immediately.
Can I see nasal polyps myself?
Large polyps near the front of the nose may be visible as a greyish or yellowish jelly like mass if you look in a mirror with a torch. However, many polyps grow much deeper in the nasal cavities and can only be seen with a medical scope.
Do polyps cause pain?
The polyps themselves do not have nerve endings and are painless. However, they cause pain indirectly by blocking the sinuses, which leads to pressure and secondary infections.
Why does my voice sound different with polyps?
When the nasal passages are blocked by growths, you lose the natural resonance in your nose. This results in what doctors call hypo nasal speech, making you sound as if you are permanently holding your nose.
Can rhinitis eventually turn into polyps?
Yes. Chronic inflammation from untreated rhinitis is the primary driver of polyp formation. This is why it is so important to manage nasal allergies and inflammation early.
Will my smell come back after treatment?
In many cases, yes. Once the polyps are shrunk with steroids or removed via surgery, scent molecules can reach the nerves again. However, if the polyps were present for a very long time, some loss of smell may be permanent.
Are polyps more common in people with asthma?
Yes. There is a strong clinical link in the UK between asthma, nasal polyps, and aspirin sensitivity, known as Samters Triad. If you have asthma, you should be particularly alert to signs of nasal polyps.
