What is asthma?

In Greek, the word asthma means "to pant." The fundamental etiology of asthma remains unknown, but it is defined as "a reversible-obstructive airway disease in which the airways become narrow, resulting in laboured breathing." Various triggers 2 cause inflammation in the bronchial tubes and can lead to permanent structural changes within the bronchial wall.

Although the exact causes of asthma are not known, there is a lot of information available on how to manage the condition.

What are the symptoms of asthma?

The inflammation that occurs in the bronchial tubes makes it hard to get air into the respiratory system.

During an asthma attack, chemical mediators such as histamine are released and the linings of the bronchial tubes become swollen and inflamed.

During an asthmatic attack, any or all of these symptoms may occur:

Generally speaking, this is possible, but exercise can be a trigger and both the person exercising and anyone with that person should be aware of the potential problems.

After several minutes of strenuous exercise, an asthma attack can occur. It is believed that the key factor in this attack is the loss of heat and water from the tissues lining the respiratory tract, as the airways work to warm and humidify the increased volume of incoming air.
