Yeah it is called galloping hypochondria.

I guess why that's why there is wheezing, shortness of breath, deoxygenated blood, elevated levels of carbon dioxide in the blood and a decreased forced expiratory volume over time. Measuring deoxygenated blood, elevated pCO₂ and blood pH requires sticking a needle into an artery to confirm the respiratory acidosis. They like to use pulse oximetry as a substitute.

Asthma is real enough, the increase in the number of people who are reported to have it is an artifact of said reporting, existence of treatments, etc.
