So now that we have a better picture of how these two health conditions function, the question becomes ... is there a relationship between allergies and asthma? It's true that those with certain allergies (usually allergies that affect the nose and eyes, such as dust mites, animal dander, mold or pollen) are more likely to develop asthma than say ... those without allergies or those with allergies in other classifications, such as food allergies. But it's also true that many of those with allergies never develop asthma at all. In addition, there are other factors that can contribute to a person's asthma. Unmonitored exercise, for example. Or other illnesses, such as colds or the flu. Scientists aren't sure what lies at the root cause of asthma. Various studies are looking at a variety of factors, including air pollution, obesity, and as strange as it might sound, even the lack of exposure to viruses and bacteria in childhood (which may prevent the immune system from growing stronger). What we do know is that exposure to indoor allergens, pollen, animal dander, grass ... in other words, allergy-related factors, are often found in asthmatics. Often, but not always. And it also appears that asthma tends to run in families. If both parents have asthma, there's actually a 40% probability their children will develop the disease as well.

Of course, new treatments are coming along all the time, and considerable research is currently dedicated to finding ways to modify, abolish or diminish the affect allergies have on the body. It's believed that with the successful control of allergies can come the successful control of asthma, particularly in younger sufferers. In the meantime, here's what we know ... asthma can be triggered by allergic reactions, but it can also be triggered by nonallergic reactions. Most asthma attacks result from exposure to allergens such as pollen, household dust, and mold. These attacks can be influenced by indoor or outdoor environments. Because a majority of asthma sufferers are affected by some form of allergies, it's worth the effor to work closely with your doctor to try to identify and control all potential allergens within your influence.
