I appreciate your concern for your mother. The question however is very inadequate. Almost all lung diseases can cause breathlessness. What is your mother's diagnosis? Is it asthma
, ILD, heart disease
or something else (or a combination of many)? You said it is asthma. Has it been confirmed? She is asthmatic since how long?
The extent of breathlessness is severe. Remember, asthma is a treatable disease and so severe breathlessness
concerns us. Your short history points toward COPD than asthma. Has she undergone any X-ray or spirometry? Has her Foracort dose been titrated?
will depend on the cause of her illness.
