Does asthma worsen with age?
With age, the immune system’s response to inflammation becomes blunted, making it harder to fight off infections that can trigger asthma exacerbations.
What causes non atopic asthma?

What is considered severe asthma?

A chest X-ray typically won’t show if a person has asthma, but can tell if something else (such as pneumonia or a foreign body in the airway) could be causing symptoms similar to asthma.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
