Food desensitization

"Patients with milk or egg allergies take increasing amounts of the food under medical supervision until they tolerate it, with the great benefit to their quality of life".


What is food desensitization?

Food desensitization or oral food immunotherapy (OTI) is a treatment that is performed in patients who have food allergies and which attempts to modify the response of the body's immune system to those foods to which the patient is allergic.

Desensitization with food consists of the administration of increasing doses of the food to which the person is allergic until a stipulated amount is tolerated. Thanks to this oral immunotherapy treatment, the patient will be able to consume a glass of milk (200 ml) a day or an egg every two days, significantly improving his/her quality of life. The intake of this tolerated amount must be maintained regularly over time in order not to lose the tolerance acquired by the body.

It should not be forgotten that milk and eggs are not only two basic foods, but as ingredients or as traces, they are present in a great amount of cooked products, so the quality of life of allergic patients is clearly affected.

Each patient is assessed individually and throughout the process is supervised by our team of allergists and nurses specialized in the control of this treatment.


Second Opinion,
the peace of mind of knowing

Our team of allergists will review the food allergy reports and tests you submit to assess the possibility of performing food desensitization.
With the maximum comfort,
without moving from home.

First shot, at the hospital.
The reaction is studied.
Very low doses:

take a higher dose,

The same pattern is followed,
by increasing the dose every

The objective is that

the acquired tolerance

By being able to eat food with
small quantities of egg or milk

Fase 6. Desensibilización alimentaria

Overcome milk and egg allergy in one week

When sensitivity to the product is low and if the child's immune system allows it, the 'target dose' can be achieved in five days.

This "express" desensitization process is indicated for patients with a not very high sensitization to these foods and an age between 4 and 10 years old.
