A severe episode of the respiratory disease asthma; generally consisting of coughing, wheezing, pressure in the chest, and shortness of breath. Often brought on by an asthmatic's trigger which can be irritants in the air(tobacco smoke,pollution, strong fumes), exercise, allergens (pollen, dander), cold air, etc. Those who have been diagnosed with the disease often have emergency medication in the form of an inhaler on hand to help hinder any sudden attacks. In severe cases, an asthma attack can result in the need for urgent hospitalization. These attacks should under no circumstances be taken lightly, as they can become life-threatening.
One of Bob's asthma triggers is vigorous exercise. Bob joins the basketball team. On the first day of practice, he was so excited that he forgot to take his inhaler beforehand. The coach had the team perform harsh running drills and Bob soon had an asthma attack.
