Causes of Nasal Polyps

Causes of Nasal Polyps

So just what are the causes of nasal polyps? There are several reasons why nasal polyps can develop. They are tied to inflammation in the nose or the sinuses however there is still a great deal that isn’t fully understood about them. Many experts have their theories and ideas regarding their causes but it can be hard to pinpoint the exact causes of nasal polyps for an individual. It is generally through a process of elimination that the underlying factors are identified and then addressed.


Numerous studies show that there may be a genetic link to developing nasal polyps. Finding out that your siblings or parents have them too could help you to find a solution that works. Many people though are embarrassed by them, so they don’t ask others around them. They don’t even want to tell their doctor that they have nose polyps.

Other people have them, but they are small and not causing any symptoms so they may not even be aware that they exist. While people of all ages can get them, they tend to develop in those over the age of 40 with men being prone to developing nasal polyps twice as much as women.

Causes of Nasal Polyps and Allergies

There are various types of allergies that can result in the development of nasal polyps. This includes, among other things, an allergy to aspirin. Allergies to dust and pollen can cause them too due to the irritation that takes place inside of the nose. A person may also be allergic to various types of chemicals that are found in the home or work environment which tend to create inflammation of the sinuses leading to polyp growth.

Nasal polyps can also be prevalent with many other respiratory diseases, such as, chronic sinusitis (due to bacterial and fungal infections), allergic rhinitis and asthma. It appears that nasal polyps are more common in people with non-allergic rhinitis and non-allergic asthma, rather than allergic types of these conditions.


When an individual suffers from an asthma attack, they tend to focus on their breathing. However, the nasal passages are also adversely affected. They become inflamed and that can trigger nasal polyps developing. This is especially true if there is any type of bacteria in the nasal passages. The more frequently that someone has asthma attacks, the more likely the polyps are to develop.

Nasal Blockage

We tend to take the complexity of the nasal passages for granted. That is until they don’t work like they should. A very common reason why nasal polyps develop for some people has to do with the passages being blocked. As a result, the mucus can accumulate and result in the area becoming inflamed and infected resulting in the perfect environment for the development of nasal polyps.

If the sinus passages are blocked for an unusually lengthy period of time you may want to get to your doctor and get them looked at so that they don’t develop into one of the causes of nasal polyps.

Food Sensitivity

Foods that you enjoy eating can actually be part of the problem relating to nasal polyps developing. A food sensitivity means that your body doesn’t react well to certain ingredients. The food sensitivity can also be experienced if certain ingredients are consumed in large quantities.

For instance if you have a big night with alcohol you may well notice that your sinuses start to block up for no apparent reason or if you regularly consume large amounts of processed foods or dairy foods, then you may notice an increased blockage in your nasal passages. Whatever happens you might have to start a process of elimination to try and find the culprit that is causing your nasal polyps condition.
