What is allergy?

Allergy is a reaction of our immune system to a foreign agent called an allergen, which can be of different origin: pollen, dust mites, dust, animal dander, even seeds or food.

Our immune system sometimes identifies these allergens as harmful to the body, even if they are not, and produces antibodies that cause histamine to be released unnecessarily.

What is histamine?

Histamine is a molecule that acts in our body both as a hormone and as a neurotransmitter of the different bile functions, sending messages between cells. For example, it is what makes the stomach produce acid or the brain stay awake, which is why antihistamines tend to make us sleepy.

In addition to these functions, it also acts on the immune system, protecting us from invading substances. The problem occurs when it detects a beneficial substance as an invader and sends the immune system to fight it. That's when it becomes our enemy, and can produce anything from minor irritation to anaphylaxis.

Most allergies cannot be cured, although there are medications to lessen the symptoms and the strength of the histamine reaction.

Symptoms of allergy

Allergy symptoms depend on the allergen involved and can affect the respiratory system, eyes, skin and digestive system. The most severe form of allergy is anaphylaxis, which can be life-threatening.

The medicines used to treat allergies are called antihistamines, which act by blocking the receptors of the histamines produced, reducing or eliminating their effects.

Types of allergies

- Nasal allergy: causes swelling of the nasal mucosa and is called allergic rhinitis. The symptoms of allergic rhinitis are similar to those of the common cold: nasal congestion, itching, sneezing, etc.

- Eye allergy: this is very common and occurs when the allergen comes into contact with the membrane of the eye. This allergy is called allergic conjunctivitis, which is not contagious but causes swelling and redness of the eyelids and conjunctiva, itching, tearing and/or sensitivity to light.
