Asthma (from the Greek) is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction and bronchospasm.[2] Common symptoms include wheezing, coughing, chest tightness, and shortness of breath.
It means having airways that are inflamed, making you and them especially sensitive to substances ranging from pollution to dust. Exposure to these and other triggers can cause the narrowing and swelling of the airways, as well as increased production of mucus, making it very difficult to breathe. An asthma attack occurs when these asthma symptoms become particularly intense.
If it important to know what trigger affects you or a family member’s asthma. In addition to pollution and dust mentioned above, secondhand smoke is another obvious one along with mold.
