A general practice of 2000 patients will contain approximately one hundred asthmatics who have had symptoms or received treatment in the past year; many of those with symptoms may not have had their disease recognised Asthma is a common condition yet it continues to be underdiagnosed and undertreated. Asthma is easy to recognise in patients who develop wheezing and airflow obstruction shortly after a specific stimulus, but there is no universally acceptable definition ofasthma that includes more chronic illness. The characteristic feature ofasthma is reversibility ofairflow obstruction over short periods of time, usually either bronchoconstriction in response to specific stimuli or bronchodilatation in response to treatment. Clinically, the important feature is the recognition ofairflow obstruction and the appropriate treatment, rather than the precise diagnostic label used. Nevertheless, the use of terms such as "wheezy bronchitis" in children with asthma, intended to spare parental anxiety, is associated with inadequate use ofbronchodilator therapy and is therefore best avoided. The particular problems ofdiagnosing asthma in young children will be dealt with in a later article. A commonly used definition ofasthma is: a disease characterised by wide variations over short periods of time in resistance to airflow in intrapulmonary airways.
