Asthma is caused by inflammation of the airways. This makes it difficult for air to pass through causing difficulty breathing. The lining of the airways can become red, inflamed and narrow with or without mucus present. This makes breathing difficult and can lead to an asthma attack, which can sometimes be fatal.
