Asthma

Asthma

Athma is a chronic lung condition where the airways become constricted by inflammation.  Of the approximately 25 million people suffering from asthma, around 7 million are children.  Asthma is often diagnosed during childhood, and its severity may increase or decrease over time. 

Patients will usually not exhibit symptoms all of the time.  Instead, they will have asthma attacks triggered by illness, stress or allergens.  During these attacks, the airways will narrow and cause chest tightness, wheezing, and a dry cough.  The patient may have a difficult time catching his or her breath, and dizziness can follow.  Severe asthma attacks can lead to asphyxiation if left untreated as the lungs will not be able to get enough air/oxygen to support the body. 

People with asthma have chronically swollen airways.  This makes them much more sensitive to inhaled allergens and other substances.  Although asthma attacks themselves can be treated to reduce the severity of symptoms, there is no cure for asthma itself.  Patients with this condition must focus on maintenance and prevention. 

One common treatment for asthma patients is a "rescue inhaler," which provides emergency relief from tightening airways.  This inhaler consists of a cartridge of pressurized albuterol vapor.  When inhaled, the albuterol works to open the airways and help the patient get more oxygen.  A similar treatment can be offered through a nebulizer when an inhaler is unavailable or impractical, such as in an infant.  Steroids like Prednisone can also help to reduce inflammation and provide relief. 

Depending on the severity of your asthma, you may be placed on a maintenance inhaler or other medications to take daily.  These are meant to reduce the frequency and severity of asthma attacks and reduce your reliance on rescue inhalers.  Even if you are on a maintenance program, however, having an emergency supply of albuterol can be helpful.  Be sure to discuss your treatment options with your doctor to determine the best way to keep yourself safe and protect the health of your lungs.
