Question

What allergies? What are their Symptoms?​

Answer 1

Answer:

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.

Common symptoms of an allergic reaction include:

sneezing and an itchy, runny or blocked nose (allergic rhinitis)

itchy, red, watering eyes (conjunctivitis)

wheezing, chest tightness, shortness of breath and a cough.

a raised, itchy, red rash (hives)

swollen lips, tongue, eyes or face
