Comorbidities

Asthma, COPD, atopic dermatitis, nasal polyps: different diseases, one shared mechanism

Do you live with a chronic respiratory or skin condition?

Symptoms such as shortness of breath, coughing, a blocked nose, itching and loss of smell can become so familiar that we end up seeing them as 'normal'.

But they are not. You can expect more from your daily life... and it starts with a better understanding of what is happening in your body.

For example, did you know that asthma, COPD, atopic dermatitis and nasal polyps can sometimes be linked? This link is called type 2 inflammation. This process triggers persistent inflammation throughout the body and is responsible for many symptoms that affect the skin, nose and airways.1-3

Type 2 inflammation: a common thread between several conditions

Don't let your symptoms take over your daily life. Watch the video below to discover the link between asthma, COPD, atopic dermatitis and nasal polyps, and to find out how a better understanding of your condition can improve your quality of life.

Did you know?

Some people experience asthma, atopic dermatitis and nasal polyps simultaneously. These conditions are all linked by the same underlying mechanism: type 2 inflammation.

 

 

Up to 50% of people with nasal polyps also have asthma.4

 

15% of people with asthma also have atopic dermatitis.5

 

Approximately 26% of people with atopic dermatitis also live with asthma.6

 

People with asthma, COPD, atopic dermatitis or nasal polyps often believe that their condition is 'under control'. In reality, however, this is rarely the case. A few figures illustrate this:

  • Among people with severe asthma, 73% believe their condition is well controlled, but only 15% actually are.7
  • In COPD, the disease can remain unnoticed for a long time: it is estimated that 2 out of 3 patients are undiagnosed.8
  • Atopic dermatitis and nasal polyps can also significantly affect quality of life,9-11 causing sleep disturbances, fatigue, social isolation or anxiety.

Living well with your condition is possible.

It all starts with a better understanding of your health and appropriate follow-up with your doctor.
