Symptoms Check List for Different Types of Allergies

Allergies are generally caused by an over reaction of an overly sensitive immune system due to some foreign substance such as cat dander, pollen, peanuts or bee venom.

Substances that cause allergic reactions are called allergens. Sometimes they can be very specifically identified (such as dust mites), but in other cases there may be a suite of things that triggers reactions (such as allergies to prawns or seafood).

Most allergens are relatively harmless such as hay fever. Allergies are relatively very common and affect about 20-30% of the population are affected by allergies to pollen and dust.

About 30 - 40% of people regularly experience some form or allergy in their lives and there is evidence that the incidence is increasing. The worst times for allergies are spring and autumn due to the increase in pollen in the air.

The most serious form of allergic reaction is anaphylaxis, which can be life threatening. Anaphylaxis requires an urgent response as a medical emergency.

People may go into cardiac arrest and may require resuscitation, oxygen and intravenous fluids. Severe cases may require injection of adrenaline (epinephrine) into the muscles to revive the heart.

Many people known to be susceptible to severe allergic reactions and potential Anaphylaxis carry an epinephrine autoinjector with them for emergency treatment.
