Summary: In modern practice we observe increasing interest in the biopsychosocial approach to issues regarding health and illness. During the last few years there has been a significant rise of morbidity rates in asthma, which together with allergy is now referred to as a contemporary epidemic. This is one of the main reasons for researchers to seek the cause of these diseases among social and psychological aspects. Many reports have been published concerning the presence of psychosomatic origins of asthma and allergy. The occurrence of a large number of coexisting psychological disorders is the main evidence for the importance of the role of integrity between psyche and soma. These psychological disorders may have an influence on the course of illness, exacerbations and treatment of allergic diseases. Our paper defines such terms as psychosomatics and psychosomatic medicine, describes psychosomatic aspects of asthma and allergy and further explores psychological issues modifying the clinical picture of these diseases. Furthermore it presents a model which organizes the therapeutic process supporting pharmacological treatment and offers practical implications that may be helpful in contact with patients with asthma and allergy.
