Asthma does not have one single cause, but allergies play a large role in at least two out of three patients. Other important factors may be genetics and family history, which is why the asthma and allergy doctors at Arcadia Allergy & Asthma take a detailed history to learn about any possible causes for your asthma. Some significant causes are also linked to pollution, exposure to tobacco smoke, unchecked respiratory infections, as well as strong scents and chemicals.
If you experience any of the symptoms listed above, there can be two major facets that cause them: inflammation due to allergies, which can result in swelling or excess mucus production within your airways. The combination of swelling and mucus production can make it much harder to breathe. Inflammation also causes spasms in the breathing tubes inside the lungs, also adding to your difficulty breathing.
