Dog AllergyThe symptoms of allergies are varied. They range from the everyday sneezing and coughing caused by pollen allergies to skin irritations to the more serious symptoms of anaphylactic shock. These symptoms are dependent upon the type of allergies an individual is experiencing. Allergies can be placed into roughly three different categories including allergic rhinitis, skin and contact allergies, and food allergies which can lead to anaphylactic shock.

Allergic rhinitis is an umbrella term used in reference to many different types of allergies. These include pollen, pet dander, mold, seasonal, dust, and even some foods. They symptoms of allergies caused by allergic rhinitis are as varied as its causes. Some of the most common are:
  • Sneezing
  • Runny nose
  • Congestion
  • Coughing and postnasal drip
  • Itchy eyes, nose and throat
  • Watery eyes
  • Swollen eyes, crusted eyelids, and/or conjunctivitis
These symptoms of allergies will last until exposure to the substance causing the problem ceases. In some cases, an individual may experience these symptoms and mistake them for a common cold. If the symptoms persist for longer than one week, they could be caused by an allergy, and a physician should be consulted.
Symptoms of Allergies
Skin and contact allergies occur when a person comes in physical contact with certain plants (poison ivy, oak, sumac, etc), medications, cosmetics, or chemicals. Symptoms of allergies caused by these factors will typically be visible on the skin, and include:
  • Red patches on the skin, or rash
  • Itchy skin
  • Inflamed skin
  • Welts or hives
Food allergies can sometimes lead to a very dangerous situation known as anaphylactic shock. However, this state can also be caused by allergic rhinitis or skin and contact allergies. Symptoms of allergies that are caused by anaphylactic shock include any of the general symptoms described above plus:
  • Swelling of joints and/or lips
  • Wheezing and/or difficulty breathing
  • Loss of consciousness
  • Headache
  • Nausea and/or vomiting
  • Abdominal cramps
  • Low blood pressure
  • Diarrhea
  • Convulsions
  • Itchy mouth and/or throat
  • Hoarseness or changing of the voice
  • Chest pain or tightness
  • Sweating
  • Confusion
Symptoms of Allergies 1If an individual exhibits any of these symptoms of allergies, in addition to the other general symptoms of allergies, seek medical attention immediately. These allergies are typically caused by a reaction to specific foods such as nuts, fish, eggs, seafood, seeds, and peanuts. If not treated immediately and correctly, anaphylaxis can cause death. However, these cases are rare, as long as appropriate medical care is received as soon as possible.

Overall, the most common symptoms of allergies are runny nose, coughing, congestion, sneezing, and the watery and itchy eyes associated with seasonal allergies. Skin allergies are the second most frequent, but can typically be cleared up with basic home care. Approximately 20 percent of people are affected by the symptoms of allergies in one way or another, but there's usually no need to worry, as long as anaphylaxis is not experienced.
