The symptoms of bronchial asthma in children, such as cough attacks, characteristic wheezing breathing, and dyspnoea, often disturb children’s good night’s rest and limit their activity during the day. The symptoms of asthma fluctuate depending on the infectious factor, sensitisers, environmental conditions, weather, air quality, and presence of other stress factors. The onset of asthma in a child may be very non-specific, making it difficult to diagnose it, implement effective treatment, and maintain appropriate control and prevention of aggravations. Asthma and allergy are often present simultaneously, complicating the diagnostic and therapeutic process, although it has been impossible to establish a fully evident and perceptible cause of asthma so far.
