BY A STAFF REPORTER: All types of asthma affect the tubes that carry air in and out of the lungs called the bronchi, or bronchi. There are several types of asthma that are classified according to either the cause of the condition or what causes the symptoms. Allergies are a major cause of bronchial asthma. Inhalation of certain substances called allergens can cause an allergic reaction, which can lead to irritation, inflammation, and swelling of the airways. Wheezing and coughing are common symptoms that can occur with an allergic asthma attack.
