Common allergies and symptoms

17in;" align="JUSTIFY">Allergy symptoms affect mostly the eyes, nose, lungs, skin and stomach. Allergies may seem different but, in fact, they all are an exaggerated manifestation of the immune system.

Hay fever

Allergic rhinitis is caused by polen and it’s the most common seasonal allergy. People can react to indoor allergens, for example dust mites, animal dander or molds. Symptoms involve swelling in the ear, throat, nose area:

  • Runny or stuffed nose;
  • Intense sneezing;
  • Itchy ears, nose or throat
Asthma

 

Asthma is a chronic disease of the airways, many times associated with allergies. It is caused by the swelling of the bronchial tubes, therefore the person cannot inhale in the lungs as much air as he or she needs. The main symptoms are:

  • coughing
  • wheezing
  • shortness of breath
Eyes Allergy

 

Eyes allergy (Allergic conjunctivitis) manifests itself by the swelling of he membranes that cover the ball of the eye and the ones underneath the eyelid. This is caused by an allergic reaction. The main symptoms are:

 

  • Redness in the eye area
  • Watery, itchy eyes
  • Membrane inflammation

Allergic Rash

The allergic rash (or atopic dermatitis) is a skin condition that appears when a person already suffers from hay fever or asthma; it is not caused by skin contact with an allergy factor. The main symptoms are:

  • Red, irritated, dry or itchy skin
  • Erruption on the face, most commonly in children
  • Erruption around the eyes, elbows and knees
Nettle rash

Also calles hives or urticaria, are a series of modifications (swelling, itchiness, colouring) on the skin level, anywhere on the body. These reactions can be caused by a food or drug allergy, but they can also be caused by exposure to certain chemicals.

The main symptoms are:

  • Red swellings on the skin
  • Intense itching
Severe Allergic Reaction

When the allergen reaches the circulatory system very quickly (for example, an insect sting, or a person eats something that is allergic to), the allergic reaction is very strong – it is also called anaphylactic shock – and it can cause death. The fact that makes it so dangerous is that it affects many organs at the same time and the organism can collapse into shock.

Any number of the following symptoms can appear:

  • Urticaria or red changes in the skin colour
  • Stuffy nose
  • Swelled throat
  • Nausea, stomach pain, vomiting
  • Breathing problems breath, wheezing
  • Low blood pressure or shock caused by deficitary blood circulation.
