Various allergy triggers include pollen, molds, dust mites, animal hair and insect bites, lactose or gluten protein present in cereals like wheat, rye, and barley cause unwanted, painful, and irritating allergies. Among all the allergic reactions, asthma has the most adverse symptoms caused by triggers like atmospheric changes, molds, pollen, and dust mites. Let us examine the most common triggers.
 

Pollen Allergy Triggers

The pollen trigger often causes asthma. An exposure to pollen triggers can lead to many allergic symptoms like nasal congestion, running nose or sneezing, wheezing or breathlessness. Pollen or more commonly the seasonal pollen allergies mainly start from January and continue until November. Therefore, people exposed to pollen from trees, flowers, grass, or weeds might get symptoms of the allergy, most distressingly through an asthma attack. Antihistamine drugs are prescribed for treating asthma or any other seasonal pollen allergy symptoms.

Mold and Mildew Spores as Allergy Triggers

If you are sensitive to allergy triggers like mold or mildew spores, you suffer from mold allergy. Mold triggers can cause asthma. Congestion, sneezing, coughing, and watery eyes are some symptoms of mold allergy. Mold as a trigger chiefly affects people during summer and autumn. Avoiding the factors responsible for mold growth can prevent asthma and other mold allergies.
 

Dust Mites as Allergy Triggers

Another common allergy trigger is dust mites found in household dust. Such allergy triggers also cause asthma and other allergy symptoms similar to the pollen and mold. Treatments for these also include antihistamine drugs, similar to the medicines prescribed for pollen allergies.
 

Animal/Pet Hair as Allergy Triggers

Animal hair and dander holds a special type of substance that creates a protein that causes a varied range of allergies. For people prone to asthma, keeping a pet-free safe zone in the home in case you have pets can help you reduce the allergic symptoms.
 

Gluten Protein as Allergy Triggers

Certain foods cause allergy in humans. Certain food triggers can cause even asthma. Gluten intolerance can often remain hidden or it can surface under specific conditions. Gluten sensitivity or gluten intolerance is among the most distressing forms of allergic reactions after asthma. Wheat, barley and rye contain a protein named gluten, which is the real allergy trigger causing numerous hazardous allergic reaction and growing severe symptoms like extreme abdomen pain, diarrhea and bloating. Gluten triggers also cause many autoimmune disorders and celiac disease. Avoiding gluten protein containing foods and consuming gluten-free diets can prevent this allergy.
