What causes excess mucus production in asthma?


Updated: 25th November 2019

Leukotrienes are chemicals that are released from the lungs in people with asthma, causing inflammation and increased mucus production in the airways. They also cause the muscles lining the airways to contract, which narrows the airways. It's also useful for preventing asthma triggered by exercise.

Keeping this in consideration, what parts of the respiratory system is affected by asthma?

Asthma affects the small airways (bronchioles) that carry air in and out of the lungs. If you have asthma your airways can become inflamed, swollen and constricted (or narrowed) and excess mucus is produced. More than 5.2 million people in the UK receive treatment for asthma - including 1.1 million children.

Which body system is affected by asthma?

The examination of the GIT amongst asthmatics has shown various pathological alterations, some of which correlate to that seen in the respiratory system, under similar conditions, and may have arisen due to bronchial asthma using the mucosal immunological system as a means of affecting this region of the body.

Where Does asthma affect?

With normal breathing, air flows in through the nose or mouth and then into the windpipe (trachea). From there, it passes through the airways (bronchial tubes), into the lungs, and finally back out again. In people with asthma, the airways are inflamed (swollen) and produce lots of thick mucus.
