Do you have asthma?
Asthma is medically defined as airway obstruction that can be reversed with medications. What symptoms do patients suffer from? Most people associate asthma with wheezing, severe shortness of breath and constant utilization of inhalers. The vast majority of patients never suffer from severe asthma on a constant basis but may have periodic attacks. Asthma symptoms may consist of cough when exercising, when laughing or when exposed to certain substances, shortness of breath, wheezing, inability to catch a full breath or becoming winded easily. Symptoms can range from extremely mild to life-threatening.
- The number of people with asthma continues to increase with about 1 out of every 12 persons in the United States suffering from asthma, or about 25-30,000,000 people.
- Asthma affects children more commonly than adults, but asthma is found in all age groups.
- Asthma is very often misdiagnosed and treated as upper respiratory tract infections or recurrent “colds”.
Airway inflammation in the common factor that affects all asthmatics. This inflammation whether it be caused by exposure to substances that cause allergies or substances that cause irritation produce swelling of the airways and mucus.
Diagnosing asthma and its severity is extremely important. Treatment depends on multiple factors but can range from avoidance of those substances that cause symptoms, rescue bronchodilators such as albuterol, inhaled steroids, leukotriene inhibitors, oral steroids or monoclonal antibodies and the usage of allergy shots or immunotherapy to recalibrate immune system and prevent inflammation.
What causes asthma symptoms?
One of the main causes of asthma is exposure to substances that cause allergies. These include indoor and outdoor substances including dust mites, cats, insects, pollens, molds, foods. Asthma can also be caused by exposure to chemicals or other substances that cause irritation of the airways as well as infections, strong smells or exercise.
Diagnosing asthma may be difficult at times. Your Asthma and Allergy specialist will take a detailed l exam, perform a physical examination and use additional tools to make this diagnosis. Pulmonary Function Testing and allergy testing are the major tools used to assess and diagnose asthma.

If you frequently experience shortness of breath or you hear a whistling or wheezy sound in your chest when you breathe, you may have asthma — a chronic condition that causes inflammation and narrowing of the bronchial tubes, the passageways that allow air to enter and leave the lungs. If people with asthma are exposed to a substance to which they are sensitive or a situation that changes their regular breathing patterns, the symptoms can become more severe.
Asthma symptoms affect an estimated 26 million Americans — 19 million adults and 7 million children — and are one of the leading causes of absences from work and school. Asthma often runs in families; according to the World Health Organization, about half the cases are due to genetic susceptibility and half result from environmental factors. Although there is no cure for asthma, effective treatments are available. Asthma can be best managed by seeing an allergist.
There are two types of asthma: allergic (caused by exposure to an allergen) and nonallergic (caused by stress, exercise, illnesses like a cold or the flu, or exposure to extreme weather, irritants in the air or some medications).
- Shortness of breath
- Chest tightness
- Wheezing (a whistling or squeaky sound in your chest when you breathe, especially when exhaling)

- Outdoor allergens, such as pollens from grass, trees and weeds
- Indoor allergens, such as pet dander, dust mites and mold
- Certain drugs and food additives
- Irritants in the air, such as smoke, chemical fumes and strong odors
- Colds, the flu or other illnesses
- Exercise (although people with asthma can benefit from some exercise)
- Weather conditions, such as cold air or extremely dry, wet or windy weather
Asthma Management and Treatment
Prevention of symptoms is the best strategy. A person with asthma should know what situations trigger an attack and avoid them whenever possible. If asthma attacks are severe, are unpredictable or flare up more than twice a week, consultation with an allergist can help to determine their cause and provide long-term treatment that controls or eliminates the symptoms.

Asthma Facts and Figures
Studies show that people with asthma who see a specialist, such as an allergist, reduce their:
- Emergency room visits
- Hospital stays
- Visits to the doctor because they are sick
- Missed days from work or school
- Health care costs
If asthma is left unmanaged or is misdiagnosed, it can be deadly:
- Asthma is among the most common chronic childhood illnesses, accounting for 10.5 million missed school days a year. It also accounts for 14.2 million lost workdays for adults.
- Every year, about 14 million Americans see a doctor for asthma. About 1.4 million patients visit a hospital outpatient department for asthma; almost 1.75 million go to a hospital emergency room.
- The number of people in the U.S. diagnosed with asthma is increasing. The greatest rise in asthma rates is among black children, with an almost 50 percent increase from 2001 through 2009.
- Researchers estimate asthma-related costs, including the direct cost of health care and indirect costs such as decreased worker productivity, at around $60 billion annually.
Many people with asthma manage the condition well and can live a healthy and productive life by avoiding triggers and following their allergists’ instructions. If left unmanaged or misdiagnosed, asthma can be fatal; about 3,300 people die from it annually.
