ASTHMA

What is Asthma?

Asthma is a lung condition that causes wheezing, coughing, and shortness of breath. It is caused by inflammation (swelling) of the lining of the airways in your lungs. Asthma is a chronic condition, which means you will probably have it the rest of your life. Some people have coughing or wheezing only during or after physical activity. This is called Exercise-induced asthma. Asthma may be mild, moderate, or severe. An asthma attack may last a few minutes or for days and attacks can happen anywhere and at any time. Severe asthma attacks can be fatal. It is very important to get treatment for asthma so you can live a healthy, active life. An estimated 22.9 million people (7.7 percent) of the population have current asthma.

How does Asthma occur?

If you have asthma, the airways in your lungs are inflamed, even when you do not have any symptoms. When your airways are exposed to irritants or allergens, the airways become more swollen and begin to make excess mucus. The muscles in the walls of the airways begin to contract. These reactions cause the airway openings to become smaller, making it harder for air to move in and out. Wheezing is the sound of air moving through the narrowed air passages. The extra mucus in the airways causes coughing.

Often asthma attacks are triggered by everyday situation and environmental factors, which typically fall into three groups:
 
1. Allergens – These make up the largest group of triggers. Pollen, animal dander, mold, mildew, cockroaches, and dust mite are common airborne triggers.

2. Irritants – These include perfumes, household cleaning products, aerosol sprays, smoke, industrial chemicals, and air pollution. People with asthma may react to even a small amount of these substances.  

3. Physical conditions – Include such things as viral infections, colds, or flu that cancause flare-ups. Exercise, weather changes, cold air, and emotional stress are other triggers in this category.

What are the symptoms?Symptoms of asthma are:
  • Wheezing
  • Coughing
  • Shortness of breath
  • Chest tightness
How is it diagnosed?We will ask about your history of breathing problems and will do a physical exam.  You may have one or more breathing tests. You may be tested before and after taking medication to measure your response to bronchodilators. A single attack of wheezing does not necessarily mean that you have asthma. Certain infections and some chemicals can cause wheezing that lasts for a short time and then does not occur again.How is asthma treated and managed?Asthma has different causes in different people, and therefore individualized therapy is wise. Personalized plans for treatment may include:

  • Environmental control measures to avoid your asthma triggers

  • Medication
  • An asthma action plan
  • A partnership between you, your family, your allergist and other healthcare
    providers
You and your allergist can work together to ensure that your asthma is well
managed, so that you can participate in your normal activities.Since asthma is a chronic disease, it requires ongoing management. This includes
using proper medications to prevent and control your asthma symptoms and to
reduce airway inflammation. There are two general classes of asthma medications,
quick-relief and long-term controller medications. Your allergist may recommend one
or a combination of two or more of these medications.
