What are the symptoms of allergies?

Almost all of us are allergic to something. Indeed, some illnesses or discomforts are caused by allergies that we do not know. While nearly half of the world’s population can be affected by allergies according to WHO data, it is important to be able to identify symptoms. There are many signs indicating the existence of a variety of types of allergies. Considering that some allergic reactions can lead to death, it is therefore necessary to know how the symptoms of allergies manifest themselves.


Symptoms of a food allergy

You know that you are a food victim when you observe an almost immediate reaction or 1 to 2 hours after ingesting the provocative food. This type of allergy is one of the most dangerous because it can be fatal. You should therefore pay close attention to the following symptoms:

  • Edema of the face;
  • Urticaria;
  • Abdominal pain, diarrhea;
  • Oral pruritus;
  • Difficulty breathing ;
  • Loss of consciousness ;
  • Cardiac arrest, in extreme cases.

If you are faced with this type of symptoms and you have any doubts, you should absolutely consult an allergist. The specialist will confirm that it is indeed an allergic reaction because it can be a decoy. Indeed, some people can develop a non-allergic hypersensitivity which can be likened to an allergy. It is therefore up to the specialist doctor to decide.

To determine if it is indeed an allergy, the allergist will do skin tests and blood tests during his examination. In some cases, the specialist may also perform a reintroduction test for the food in question. If the tests are conclusive, the patient will be prohibited from consuming this offending food and will be recommended an emergency kit with an adrenaline pen.

Symptoms of skin allergy

A skin allergy can take different forms. Its symptoms vary depending on how long it takes to appear. We distinguish :

Urticaria which can result from an allergy to drugs, food or hymenoptera venoms. This form may worsen with the onset of facial edema or severe anaphylaxis. This type of reaction is very dangerous.

The appearance of eczemas that present with itching or erythema with dry patches.

The appearance of a set of skin lesions in reaction to the application of a drug or an allergen to the skin.

Skin allergy can be caused by various contacts with products such as metals, cosmetics or chemicals or even drugs. This is why the allergist must give the patient an interview to be able to determine the cause very quickly. This is how he can establish the type of allergy from which the patient suffers and the treatment indicated.

Symptoms of respiratory allergy

A respiratory allergy manifests itself in several ways, although the main symptom is difficulty in breathing. The latter is caused by a dry cough, wheezing or tightness of the cage thoracic. It can be manifested by:

  • Rhinitis which is inflammation nasal mucous membranes;
  • Conjunctivitis which is inflammation the conjunctiva of the eye which turns red;
  • Asthma which is inflammation respiratory tract.

If you notice these symptoms, a visit to the allergist will help determine the source of the allergy. To treat this type of allergy, desensitization of the allergenic agent is necessary.
