There are common threads between seasonal allergies and asthma. The symptoms that are produced by allergies can be the same symptoms that are produced by asthma, and asthma can be triggered by pollen.
According to the Asthma and Allergy Foundation of America, allergic asthma (extrinsic) is the most common type of asthma. It is triggered by inhaled allergens such as pollen and produces asthma symptoms including coughing, wheezing and shortness of breath.
The allergens that trigger asthma will differ for each person. Among the causes are pollen, weather, and air pollutants. If you suspect you may have asthma, it is important that you consult a medical professional. They can help with a treatment program to help with your symptoms.
