What happens during an asthma attack? An asthma attack is when the symptoms of asthma become worse. This can happen suddenly. It may also happen gradually. During an attack the airways become narrower leading to the symptoms: An irritant called a trigger reaches the airways. This causes the muscles in the airways to contract. The airway becomes inflamed. It produces excess mucous. This leads to coughing. The airway becomes narrow leading to wheezes and breathlessness.
