Datamonitor Healthcare Respiratory Disease Analysis: Asthma
August 10, 2020Asthma is a chronic respiratory condition characterized by recurrent wheezing, coughing, and breathlessness, which occur in acute events known as exacerbations. Often triggered by factors such as exercise, allergen or irritant exposure, change in weather, or viral respiratory infections, these flare-ups can vary significantly in frequency and severity. Attacks consist of swelling of the lining of the bronchial tubes, which narrows airways and results in a reduction of airflow into and out of the lungs. Historically considered to be a single disease, asthma is now viewed more as an overlapping assemblage of individual phenotypes with various underlying pathophysiological processes leading to symptoms.
The Global Asthma Report has estimated that asthma affects 339 million people worldwide. It is the most common noncommunicable ailment among children, and is often poorly controlled. Asthma can be difficult to define and diagnose, and some diagnostic measures are physically demanding on the patient. Currently, there is no “gold standard” in diagnosis, which makes finding a standard definition difficult. Some studies suggest that over a quarter of adults diagnosed with asthma do not have clear evidence of this condition.
