Asthma is a long-term inflammatory disease of the airways of the lungs. Variable and recurring symptoms include reversible airflow obstruction, and bronchospasm.
Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath.
There are certain allergens or irritants such as cigarette smoke, chemicals, mold, dust, or other substances commonly found in the person's environment that can trigger asthma.
Different illnesses, viruses, or infections can also be a factor in adult asthma.
Respiratory problems during infancy and childhood can cause wheezing which develops into asthma later on in life. Some children who experience viral respiratory infections go on to develop chronic asthma.
