Allergies: symptoms

The symptoms of allergies are very different. They can appear more or less brutal and violent, on different organs and devices. Here are some of these symptoms:

1 - Respiratory allergies.

They are caused by air allergens, pneumallergens, such as pollen but also molds, mites, animal hair or chemicals such as detergents.

In children, food allergy can also be expressed by respiratory signs that range from rhinitis (hay fever) often associated with conjunctivitis to the asthma attack. The symptoms are: runny nose, sneezing, scratching nose ...

2 - The cutaneous manifestations.

These allergies can appear very early in life, this is the case of atopic dermatitis that strikes infants from the first months of life. The baby suffers from eczema that scratches more or less. Severe forms of eczema are quite impressive.

This allergy can be food related to a food introduced early, such as:

  • the egg white,
  • gluten (allergy to gluten)
  • peanut (allergy to peanut).

These forms of allergy disappear most often with the years, sometimes in adulthood. Later, these people may be the victims of contact allergies (jewelry, watch band) or professional dermatitis due to contact with irritating industrial products (cement, pesticides, heavy metals ...). The symptoms of this allergy is the appearance of a red skin, which scratches, and which desquamates.

3 - Quincke's edema.

Quincke's edema affects the subcutaneous tissues and the mucous membranes especially of the throat. There is an edema of the hypodermis. The symptoms are pretty impressive. Quincke's edema can affect any part of the body, but especially the face. It is dangerous and requires urgent medical treatment because it can cause asphyxiation due to edema located in the throat.

4 - Anaphylactic shock.

Anaphylactic shock is a sudden allergic event that can be fatal for cardio-circulatory failure. It imposes urgent measures such as the administration of adrenaline. Some allergens are more likely to cause shock in sensitized people:

  • foods such as groundnuts, fish or shellfish
  • medicines such as antibiotics (beta-lactams) or nonsteroidal anti-inflammatory drugs;
  • the venoms of snakes and wasps.
