Allergy Symptoms

Different people will have different allergy symptoms, depending on what is causing the allergies and the severity of the allergic reaction. For airborne allergies, signs and symptoms can range from mild itching and sneezing to severe hives and shortness of breath. Nasal congestion, coughing, and watery eyes are common symptoms. Other symptoms, such as anaphylactic shock, are the result of a more severe allergic reaction.

 

Allergy Signs and Symptoms: An Overview

An allergy is the body's hypersensitivity to substances in the environment. Depending on what is causing a person's allergies, symptoms can range from mild itching, sneezing, or eczema (inflamed, itchy skin) to severe hives, hay fever, wheezing, and shortness of breath.
 
An extreme allergic reaction can result in anaphylactic shock, a life-threatening situation in which a person's airway swells shut and blood pressure drops.
 
This eMedTV article will discuss symptoms related to airborne allergies. Airborne allergies include seasonal allergies, such as hay fever (also known as pollen allergy), and perennial (year-round) allergies to things like dust or pets.
 
The medical names for these symptoms include allergic rhinitis and rhinosinusitis.
 

Common Symptoms

Allergy symptoms are familiar to many people.
 The most common symptoms of airborne allergies include:
 
  • Sneezing, often with a runny or clogged nose
  • Coughing and postnasal drip
  • Itching eyes, nose, and throat
  • Watering eyes
  • Conjunctivitis (inflammation of the membrane that covers the eye)
  • "Allergic shiners" (dark circles under the eyes caused by increased blood flow near the sinuses)
  • "Allergic salute" (in a child, persistent upward rubbing of the nose that causes a crease mark on the nose).
