Description

---

Allergies occur when your immune system reacts to a foreign substance - such as pollen, bee venom or pet dander - or a food that doesn't cause a reaction in most people. Your immune system produces substances known as antibodies.

Some of the symptoms of an allergic reaction include:

• Itchy, watery eyes.
• Itchy nose.
• Sneezing.
• Runny nose.
• Rashes.
• Hives (a rash with raised red patches)
• Stomach cramps.
• Vomiting.

Peanut allergies are among the most common and most fatal of the food allergies, causing anaphylaxis more often than the other four we mention. For some, even a little contact with peanuts can cause an enormous reaction.
