Food allergy! Causes and manifestations

Allergy occurs when the body's immune system overreacts to exposure to a certain substance.

Allergic symptoms are more severe in infants and children, but they can appear at any age, even if until then you had no problems with a certain food that you ate without problems for years.

Food allergies can be of 2 types:

1.Immediate allergy

This manifests itself immediately after the ingestion of food, is mediated by antibodies of the class of immunoglobulins E (IgE) and is the type of reaction that can potentially be severe up to anaphylactic shock.

2. Delayed allergy

Reactions can occur even after 6 hours after ingesting the food.

Late allergic reactions are mediated by other types of immune reactions, with the involvement of memory cells, which will recognize and trigger the signal of allergic inflammation in the tissues.

The symptoms take various forms: oral, gastrointestinal, cutaneous, cardiovascular, systemic manifestations, so the symptoms can vary from diarrhea and vomiting, headaches and nausea, skin itching, palpitations and panic attacks.

What is anaphylaxis (anaphylactic shock)?

Anaphylaxis is a potentially fatal reaction that includes difficulty in breathing and the induction of a state of shock throughout the body; reactions can simultaneously affect different parts of the body (for example, stomach pain accompanied by skin rash).

Anaphylactic shock can cause the following signs and symptoms: feeling of weakness, dizziness, headache, ringing in the ears, visual disturbances caused by arterial hypotension, which can progress to vascular collapse.

If you have symptoms associated with an allergy, go to the nearest medical point to benefit from correct medical care!

Health, better than all!
