My attention has been drawn to this particular study and to other aspects of this matter. Therefore, I am aware of the work that is being done in this area. The causation and treatment of asthma are very complex issues involving a combination of environmental, physiological, psychological, metabolic and other factors.
As regards the particular point of this study, namely, the Buteyko breathing technique, I would make the following observation. The use of any treatment modality in any area of medical practice is a matter for individual practitioners based on best practice, as reflected in the research literature, standards and guidance provided by professional bodies and practitioners' individual experience. The Department is not in a position, therefore, to advocate the use of any particular programme of treatment in the complex and difficult area of asthma management.
