A question we are often asked…what is a nasal polyp?
Typically, a polyp is an abnormal tissue growth that projects from a mucous membrane. In the nose and sinuses, however, nasal polyps develop a bit differently. The mucosal lining of the nose and sinuses gets heavy due to inflammation or excess mucous gland production. The heavy tissue begins to “plop down”, sort of like stalactites. causing an obstruction.
The most common polyps in the nose and sinuses, unlike polyps in the intestines, are not tumors or growths. If the swelling can be reduced medically, and there still is elasticity in the tissues, they can go back up, and basically resolve. However, once this elasticity is gone, the polyps may need to be removed surgically.
Polyps and Allergies
Although no one knows exactly why polyps arise in some sinuses and not others, there does seem to be a correlation between polyps and allergies or asthma. This link is not fully understood, however, and the development of polyps is more commonly related to inflammation. The good news is that polyps are typically benign, but can be extremely irritating.
While some people have small nasal polyps and never know it, larger polyps can:
- Block the airway, making it difficult to breathe
- Block the opening to the sinuses, causing recurrent sinus infections
- Block the tubes to the ears, causing middle ear infections
If you suffer from allergies, asthma, chronic sinusitis, or nasal mastocytosis, you may be at risk for nasal polyps.
It is important to ask, “What is a nasal polyp?” because occasionally, tumors can be mistaken for nasal polyps. Additionally, polyps themselves may bleed or cause pain.

Frequently Asked Questions
A nasal polyp is an abnormal tissue growth that develops from the mucosal lining of the nose and sinuses due to inflammation or excess mucus production. Unlike typical tumors, these polyps often form when the mucosal tissue becomes heavy and droops, causing obstruction.
Nasal polyps differ from intestinal polyps in that they are generally not tumors. They result mainly from swollen mucosal tissue that loses elasticity and droops, whereas intestinal polyps are often true growths or tumors.
There is a recognized correlation between nasal polyps and allergies or asthma, although the exact cause of polyps is not fully understood. Polyps commonly develop due to inflammation, which may be linked to allergic reactions or respiratory conditions like asthma.
Large nasal polyps can block the airway, making it difficult to breathe. They may also obstruct sinus drainage leading to recurrent sinus infections, and block ear tubes causing middle ear infections.
If the mucosal tissue still retains elasticity and swelling is reduced medically, nasal polyps can recede and resolve without surgery. However, if the tissue becomes too stretched and loses elasticity, surgical removal might be necessary.
You should consult a doctor if you experience symptoms like difficulty breathing, frequent sinus or ear infections, or if you suspect nasal polyps. It's important because sometimes tumors can be mistaken for polyps, and polyps themselves can cause bleeding or pain.
