Although asthma can be managed relatively easily, it remains a potentially deadly illness. While genetics can play a large role in the development of asthma, environmental factors can also cause a person to develop the illness. Nor does a person have to be born with it. Specialty Asthma and Allergy Doctors see thousands of adults a year who never suffered as children. Furthermore, the American Academy of Allergy Asthma & Immunology, roughly 8% of adults in the US had asthma.
A number of factors may increase your asthma risk:
Allergens both inside the home, such as dust mites and pet dander, and outside, such as pollens and dust.
Smoke, whether from a smoker or fire, can be both a factor and trigger for asthma.
Certain chemicals used for cleaning, particularly those that have fumes or include particles that can be airborne.
Environmental pollution can be a significant cause for the development of asthma, and allergies. If you live in an area where smog is a frequent problem, particularly in the summer months, this can be a serious problem for your lungs, even beyond causing the development of asthma.
Acid reflux, more commonly known as heartburn, can contribute to the development of asthma. When the digestive system pushes food back up the esophagus, stomach acid is included with the food, burning the esophagus. With the close proximity of the esophagus and airway passages, the acid may also trigger asthma.
Obesity is also a likely contributing factor as a greater percentage of those who have asthma are obese, compared to those who are overweight or at a normal weight.
