Asthma is a chronic disease involving the airways in the lungs. These airways, or bronchial tubes, allow air to come in and out of the lungs.
People with a family history of allergies or asthma are more prone to developing asthma. Many people with asthma also have allergies. This is called allergic asthma.
Occupational asthma is caused by inhaling fumes, gases, dust or other potentially harmful substances while on the job.
