Quincke's edema is swelling of the tissues, which occurs when a person comes in contact with the substance to which he is allergic. It must then act very quickly, because in the absence of any treatment a fatal anaphylactic shock may occur.
Most people live in harmony with the harmless substances that surround them. When an element is recognized as foreign by the body (it is called antigen) the immune system will want to defend the body by fighting the intruder. When dysfunction of this immune system occurs, innocuous substances will be considered as antigens and in some cases induce a general allergic reaction.
This consists in releasing molecules (histamine and lymphokines). Both will act on the vessels by dilating them and causing swelling in the tissues.
If the reaction takes place immediately after contact with the allergenic substance, one can within minutes or even seconds, face angioedema, which can be followed by anaphylactic shock. It must then react immediately to avoid aggravation. The more the person has already had a history, the faster must be the reaction.
The general feeling of uneasiness of the person must arouse alertness. It is accompanied by a multitude of signs that appear almost simultaneously:
- hot flushes
- generalized urticaria on the body
- stomach ache
- voice modification
- heart that beats very fast
- drowsiness (especially in children)
- swelling of the area of the eyes, tongue, lips, pharynx
At this stage of swelling of the face and if it is not stopped, the airways where the air passes will shrink more and more. This is how Quincke's edema can lead to anaphylactic shock that can end in cardiopulmonary arrest. Hence the importance of taking this symptom very seriously.Want to react, share your experience or ask a question? See you in our FORUMS Allergy or A doctor answers you!
