The chronic obstructive airway dis- wheeze caused by variable or intermittent nar- eases can be divided into whether the obstruc- rowing of the intra-pulmonary airways. In the former case the severity of these symptoms has a wide range, patient usually has asthma, in the latter case from very mild intermittent with symptoms only chronic obstructive pulmonary disease, abbrevi- upon provocation, to severe persistent with large ated COPD. There is no precise definition definitions, and the division is only meant as of asthma, and therefore the prevalence is hard to a first approximation. We know, however, that it is commoner matory diseases mainly of the lower respiratory in children than in adults, and more common in tract: in asthma there is an inflammatory pro- boys than in girls.
