Asthma is a predisposition to chronic inflammation of the lungs that reversibly narrows the airways (bronchi). Your airways are essentially tubes that carry air in and out of your lungs. Asthma causes the inside walls of these airways to become swollen and sore, making them very sensitive. As a result they can react strongly to items that you are allergic to. When your airways react to these items then they get narrower causing your lungs to get less air. This can cause coughing, shortness of breath, wheezing and chest tightness – all symptoms of asthma.
When the asthma symptoms are worse than usual it is called an asthma attack. Severe asthma attacks can cause your airways to close so much that you do not get enough oxygen to your vital organs. Severe asthma attacks can cause people to die.
Asthma attacks can be prevented by avoiding triggering factors such as rapid temperature changes or allergens. Other preventative methods include drug treatment such as inhaled corticosteroids and then long-acting beta-2 agonists when necessary.
Typically asthma is the result of genetic and environmental factors, which can influence the severity of the asthma and how well it responds to medication. It affects approximately 7 percent of the United States’ population.
The airway obstruction in asthma is typically reversible. However, if it is left untreated asthma can cause a chronic inflammation of the lungs and irreversible obstruction.
