The most common allergens are found in connection with handling animals, pollens, house dust, house dust mites, molds, some drugs and many foodstuffs, especially fish, eggs, milk and nuts. Bee and wasp stings may cause allergic reactions and occasionally these stings can have fatal results. Additionally, feathers, wool, dyes, cosmetics and perfumes may sometimes act as allergens. Common Allergies Allergic reactions or diseases may involve any part of the body, the most frequently involved being the nose and chest with symptoms resulting such as hay fever, rhinitis or asthma. The skin and eyes also commonly show allergic symptoms.
Anaphylactic shock is severe allergy which affects many organs at the same time.
This can cause a rapid decrease in blood pressure, fainting and, occasionally, death. Such reactions though, are rare. If you suffer from hay fever, the pollens of grasses, weeds and trees are the main causes of this type of allergy, although mold spores can also cause the symptoms. The lining of the nose becomes swollen and exudes a runny discharge. Spells of sneezing and itchiness of the throat and palate also occur and the eyes may be similarly affected.
