Sadly, there is currently no known cure for asthma. However, numerous treatments have proven to be exceptionally useful in reducing and managing asthma symptoms so that those who suffer from this condition can live as unhindered from it as possible. When asthma is managed effectively, patients can typically experience any or all of the following:   • Absence of breathing difficulties, such as coughing or wheezing, on most days • Sleep through the night without asthma symptoms disrupting your sleep • Exercise without experiencing any asthma symptoms • Pass a spirometry or long-function test • Minimal reliance upon quick-relief medicine (no more than three times per week)
