Allergies are caused by your immune system reacting to a foreign substance such as pollen, dust, mold or dander (flakes of skin from certain animals), or certain foods.
Allergies can cause inflammation in your sinuses, nasal passages, airways, and lungs – all of which are parts of your respiratory system. This inflammation can result in:
- nasal congestion
- watery eyes
- shortness of breath,
- and other allergy symptoms.
Allergies can trigger an asthma attack (allergy-induced asthma). Asthma is a condition in which the airways swell and produce extra mucus, causing difficulty in breathing, coughing, wheezing and chest tightness, among others.
Individuals with allergies are also at higher risk for respiratory infections such as bronchitis, as well as hypersensitivity pneumonitis, a type of allergic reaction that causes inflammation of the lung’s air sacs.
Talk to your doctor for more information on allergy prevention and management.
