What’s the Connection? Nasal Polyps and Coexisting Conditions

Slide 2:

Nasal polyps are growths inside the nose or sinuses. 

They’re not cancerous, but large polyps can:

• Make it hard to breathe

• Harm your quality of sleep

• Reduce your ability to smell and taste

• Cause infections 

Certain allergies and conditions that cause inflammation can increase the risk of getting nasal polyps. 

Slide 3:

In some people, the immune system senses and tries to attack infections that aren’t really there. This is called type 2 inflammation.  

Type 2 inflammation may be the link between nasal polyps and many other conditions that go along with them, such as:

Slide 4:

Asthma and other respiratory diseases

Conditions that impact the airways and lungs making it harder to breathe

Slide 5:

Atopic dermatitis, also known as eczema

A chronic (long-term) condition that makes skin dry, itchy and inflamed 

Slide 6:

Food allergies 

An immune system overreaction to eating certain foods

Slide 7: 

Eosinophilic esophagitis (EOE)

An immune system disease that makes it difficult to swallow

Slide 8:

Prurigo nodularis

A chronic skin condition that causes firm, severely itchy bumps 

Slide 9:

Having nasal polyps along with one of more of these conditions can worsen symptoms and cause them to recur. 

Because type 2 inflammation may be the cause of both nasal polyps and other condition(s), treating the inflammation might improve symptoms.

Slide 10:

If you have nasal polyps and one or more of these other conditions, talk to your healthcare provider. Understanding the underlying cause of your nasal polyps can help your HCP create the right treatment plan for you.
