Asthma is a chronic and long term condition which effects a person’s lungs causing them to become inflamed and thus narrowing the airway. Its like trying to breath through a snorkel that someone is squeezing closed.
It is hard to breath during an asthma attack because the airways get irritated, causing the muscles around them to contract and the cells to create more mucus, both of which block airflow. It can be genetic or environmentally caused, and attacks can flare up due to allergens or other irritants. A long list of genes are associated with asthma, most of which have something to do with regulating inflammation.
