Asthma is a condition of the airways, which are the structures that allow air to move from your mouth and nose to your lungs. It causes the muscles of the airways to tighten, as well as the lining of the airway to swell and inflame, resulting in the production of sticky mucus. Coughing, wheezing, shortness of breath, and chest tightness might occur as a result of these changes, which restrict the airways and make breathing difficult. Asthma is a common reason for children to visit the doctor, miss school, or be admitted to the hospital. In fact, asthma is thought to affect one out of every ten Australian youngsters. Your child should be able to live a healthy, active life if their asthma is well-managed.
