Study of Asthma Step-up in Real Life (SURFE)
The goal of this observational study is to learn about the frequency needed for stepping-up treatment in patients with mild and moderate bronchial asthma. The main questions this study aims to answer are: * What is the frequency and duration in which patients of asthma need to step up their treatment? * Can the criteria described in this study be applied and validated to test need for step up of asthma treatment? Participants will follow the treatment they are already receiving according to established guidelines and will be asked for regular visits for examination and spirometry. They will record symptoms score, each time they use the prescribed rescu inhaler, and morning and evening peak expiratory flow.
