Nervous system conditions and consciousness


When your child is experiencing a severe allergic reaction this may have impact on his/her level of consciousness. In an allergic reaction to tree and/or grass pollen (hay fever), house dust mites and pets a very severe allergic reaction with impact on your child’s consciousness will not occur that quickly. In an allergic reaction to insect sting, a drug allergy and a food allergy that risk does exist though.

Below a number of symptoms are stated which can be caused by an allergic reaction. These symptoms are all related to the consciousness:

  • Feeling light-headed
  • Double vision
  • Dizziness
  • Less responsive
  • Fainting
  • Unconsciousness

Certainly the last two phenomena are mainly seen in a very severe allergic reaction, also known as an anaphylactic reaction.

What is an anaphylactic reaction?

Anaphylaxis is a potentially severe or life-threatening allergic reaction that can occur very quickly, as fast as within a couple of minutes after exposure to the allergen. It can be triggered by an allergy to a particular food, biting or stinging insect and/or medication.

The symptoms occur in different organs: the eyes, the skin, the gastrointestinal tract and the lungs. Your child often gets multiple symptoms at once. Worst case scenario is a rapid and strong fall in blood pressure which will make your child lose consciousness. When this situation occurs an anaphylactic shock is in progress. This is a life-threatening emergency situation that can be fatal.

Please contact a physician as soon as possible in case of an anaphylactic reaction and/or dial 112.
