Asthma and Allergies on the Rise in the US

Cases of asthma and allergic diseases are increasing worldwide, not just in low and middle income countries but in developing countries, including the United States, as well. Furthermore, studies have shown the incessant increase in the complexity and severity of allergic diseases and asthma especially in children and young adults. For instance, a study conducted by the Centers for Disease Control and Prevention, food allergies among children increased by approximately 50% between 1997 and 2011. Meanwhile, for every 12 people in the United States, at least one is suffering from asthma. That is about 25 million people. From 2001 to 2011, the CDC claims that the number of Americans suffering from asthma rose by 28 percent, and the greatest rise in rates of asthma was among children.

The rise in asthma and allergy rates is observed due to many factors. First, it has been theorized that too much cleanliness could be the blame. The “hygiene hypothesis” proposes that children are insusceptible to dirt, bacteria, and other infectious agents early on, and their under-stimulated immune systems goes on the offense when subjected to benign stuff such as food. Previous studies have shown that children in day cares, known as nests for spreading germs, suffer from fewer allergies than those raised in homes with limited contact with other kids. However, there is still no proof as to the validity of the hygiene hypothesis.

Another factor that could also be contributing to the allergy increase is the rise in carbon dioxide levels in the atmosphere. The third one to consider is smog and other types of air pollution. A test tube experiment has given sufficient evidence for the link between pollution and allergies, however it has remained difficult to prove in large populations. Moreover, climate change, change in ambient temperatures have caused diverse consequences on human health, including the trigger of allergies and asthma.

Although several factors have been enumerated, the real culprit for allergies depends on the symptoms specific to each individual person.

Stuart H. Agren, M.D.

Stuart H. Agren, M.D. completed his undergraduate studies at the University of Utah and went on to earn his Doctor of Medicine from Tulane University School of Medicine in 1974. He completed additional training at L.D.S. Hospital in Salt Lake City, Utah and then established his private medical practice starting in 1975. Dr. Agren completed a mini-residency in Industrial Medicine at the Robert Johnson School of Medicine at Rutgers University and also completed training to become a certified Medical Review Officer.

Dr. Agren was the Medical Director at TRW and McDonnell Douglas in Mesa, Arizona and at Stauffer Chemical and Kennecott Copper in Salt Lake City, Utah. He also served as an adjunct faculty member at Arizona State University.

In his private medical practice, Dr. Agren specialized in family practice and allergy. In his work as a private practice allergist, he was one of the first doctors in the country to prescribe sublingual immunotherapy to his patients as an alternative to subcutaneous immunotherapy (allergy shots). He has also been a trailblazer in the field of food allergy treatment and research, developing a program to treat multiple food allergies simultaneously using sublingual immunotherapy. Dr. Agren has been featured on local CBS, NBC, and ABC news affiliates and won the peer-nominated “Top Doc” award from Phoenix Magazine.

After 20 years in private practice, Dr. Agren became the Founder and President of AllergyEasy, which helps primary care physicians around the country offer allergy testing and sublingual immunotherapy treatment to their patients. Over 200 physicians in over 32 states use the AllergyEasy program to help their patients overcome environmental and food allergies and asthma.
