The two most common allergies are food allergies, which occur when the body has an adverse reaction to a certain food that has been consumed, and seasonal allergies from grass, plants, tree pollen or mold. Drug allergies may affect many Americans as well. Drug allergies occur when the body has a negative reaction to a medication and the immune system responds causing an allergic reaction.

Pet and seasonal allergies may cause itchy eyes and sneezing, while skin allergies may cause rashes and itchy skin. Allergies may be hereditary, as children whose parents have allergies may be more prone to developing allergies.

Symptoms of the various types of allergies may vary. Food allergy symptoms may include a tingling in the mouth and swelling of the lips, cramps, upset stomach, diarrhea, skin reactions such as hives, stuffy nose and dizziness.
Symptoms of drug allergies may include hives, eczema, rash, blisters, coughing, runny nose, breathing problems, fever and in severe reactions, anaphylaxis. Anaphylaxis may include hives, trouble breathing, and may be deadly so emergency treatment is often required.

The best way to avoid allergies may be to avoid those things that cause allergic reactions. A doctor may prescribe medication that may help stop or relieve an allergy if a food or drug that causes an allergic reaction is ingested.

Emergency treatment may be required if ingesting a drug or food causes a severe reaction. Individuals with drug allergies may wear bracelets to indicate their allergies. This may help alert physicians or paramedics of the allergy and could save the individual's life.

Seasonal allergies and pet allergies may be harder to avoid. Nasal sprays and medications may help patients find relief from these types of allergies. Allergies may also be linked to certain dietary habits and altering diet habits has been linked to preventing certain allergies (such as with gluten).
