Food Allergy

Nearly 2% of adults have a food allergy. And there are more and more!

The reasons?

Internationalization of food consumption (kiwi or sesame, for example) and increasingly frequent consumption of products from the food industry (contamination of food by allergens during storage, manufacturing, packaging … ).

The main manifestations of contact allergy are atopic eczema, urticaria or angioedema, digestive and respiratory disorders, and anaphylaxis.

5 food groups are responsible for the majority of food allergies:
THE LATEX GROUP  : avocado, kiwi, banana, chestnut.
THE GROUP “ROSACEA”: apricot, cherry, raspberry, peach, pear, apple, plum.
THE GROUP “NUTS”: almond, hazelnut, walnuts, brazil nuts, cashew nuts, pecans, pinion, pistachio.
THE “OMBELLIFERES” GROUP: dill, carrot, celery, coriander, fennel, anise seeds, caraway seeds, parsley.
THE “WHITE EGG AND PEANUT” GROUP 
BUT ALSO: crustaceans, sesame, lupine, curry, sheep’s milk, meat, etc.

ATOPIC ECZEMA

Atopic eczema is a disease that affects the skin and mucous membranes. The most common symptoms of this disease are:

  • Irritation lesions occurring on very dry skin
  • Redness
  • Itches
  • Desquamations (skin shovel) and crusts sometimes

In young people, eczema is mainly located on the wrists, knees or elbows but also on the face and upper body.

QUINCKE URTICARIA OR EDEMA

Urticaria is an itchy rash that appears on the skin. The main symptoms of urticaria are:

  • Lesions (which look like nettle bites)
  • Red plates
  • Severe itching

When urticaria is located in the head, hands or feet, it becomes a swelling that can become very impressive especially in the face (edema inside the mouth or throat).

In case of edema, you must immediately call the SAMU by dialing 15.

DIGESTIVE AND RESPIRATORY DISORDERS

Symptoms

  • nausea
  • vomiting
  • Stomach aches
  • Diarrhea
  • Constipation
  • Stuffy nose
  • Itchy nose
  • sneezing
  • Red eyes
  • Eyes that sting, scratch or cry
  • Difficulty breathing, whistling …

When the whole body reacts: there is urgency!
We then speak of “anaphylaxis”. It is a serious manifestation of food allergy. It will often start with allergic signs in the skin (hives), mouth and throat (tingling, swelling) and then continue with breathing difficulties. There may even be a drop in blood pressure with a loss of consciousness. It is called an anaphylactic shock, it is a real life emergency, it is treated by the injection of adrenaline.
