Commonest allergy symptoms in adults



Another common allergy trigger among North Americans is pollen. And pollen allergies can act if you share an environment with trees, grass, and flowering plants. Pollen allergens are airborne, so they are especially difficult from spring through fall when plant life is in bloom and pollen can be inhaled.

Sea food

Seafood allergy is one of the most common food allergies in adults, with more than 2% of American adults affected. Shellfish allergies also usually develop later in life, unlike many others. So not only do sufferers have to say no to shrimp, oysters, lobster, clams, mussels and crab; they also need to be wary of coming into contact with things like vitamins (i.e. glucosamine), pet food, and restaurant cross-contamination.

animal hair

Sure, you love Fido and Fluffy, but as soon as they crawl into your lap, you end up with a runny nose and watery eyes. Pet hair allergies come from the oil that animals secrete from their coats as well as from the proteins in their hairs.


Even though more children are affected by egg allergies, they are still a concern for 20% of them who take the reaction with them into adulthood. Eggs are also often hidden in the sneakiest places, including in vaccines, medicines, anesthetics, and baked goods.
