Allergies can be seasonal (worsening during certain times of the year, such as pollen allergies in the spring) Common allergens include weed or grass pollen, dust mites, animal dander, mold, insect stings and a variety of food types, such as eggs, shellfish, nuts and grains. If you come in contact with something to which you are allergic, your immune system considers it dangerous and releases a chemical called histamine to counteract it.
The release of histamine can cause a variety of symptoms, including a skin rash, headache, sneezing, runny nose, swelling, nausea and diarrhea. The most severe reaction, known as anaphylaxis, can be life-threatening.
