Triggers of atopic eczema during childhood

How is it related to the atopic process?

Triggers of atopic eczema change throughout a child's life, as well as the development of immunity, digestion, skin and nervous system. What causes eczema in a baby may not be the same problem in a toddler or school-age child.

It is this development that is described by the term atopic march.

What is atopic march?

The atopic march refers to a typical sequence of atopic diseases that appear in a certain temporal order in some children:

• frequent food allergies in infancy,
• allergic rhinitis in toddlers and preschoolers,
• some children subsequently develop asthma.

It is important to know that the atopic march is not fate. It is a description of a frequent development, not an inevitable scenario. By working with triggers early, its course can be significantly influenced or stopped.

0–1 year: baby

Diet and immature immunity play a major role

In the first year of life, the immune system is immature and very sensitive. The skin and intestines are still maturing, and the permeability of the mucous membranes is higher.

The most common triggers of eczema during this period:

• food allergens (through breast milk or directly in complementary foods),
• immature gut microbiome,
• diseases, vaccinations, teething,
• household chemicals (detergents, cosmetics).

At this age, eczema is very often the first sign of an atopic process. This is where targeted work on diet and the intestines makes the most sense.

1–3 years: toddler

Combination of diet and environment

In toddlers, the immune system reacts in a more complex way, and the child encounters more stimuli.

Common triggers:

• persistent or newly emerging food allergens,
• repeated infections and antibiotics,
• body stress (lack of sleep, illness),
• expanding the diet to include industrially processed foods,
• contact with environmental allergens.

Eczema can:

• improve and return again,
• or move into other forms of hypersensitivity (runny nose, cough).

3–6 years: preschool age

The environment and respiratory tract come to the fore

During this period, the atopic march begins to shift in some children:

• made of leather,
• into the respiratory tract.

Triggers of eczema and other problems:

• pollen and dust allergy,
• mold, mites,
• stress and emotional strain,
• poor quality diet with high sugar content,
• weakened microbiome.

Eczema may be milder, but you may experience:

• allergic rhinitis,
• chronic phlegm,
• coughing or wheezing.

School age and adolescence

Nervous system, stress and long-term strain

In older children and adolescents, they play a greater role:

• stress,
• hormonal changes,
• long-term strain on the body,
• quality of diet and sleep.

Eczema can:

• to worsen significantly again,
• or persist in a milder but chronic form.

What follows from this?

Atopic eczema:

• not an isolated skin problem,
• is part of the broader picture of immune development,
• and often represents the first step in the atopic process.

The sooner you can:

• reduce the inflammatory burden,
• adjust your diet,
• support the intestines and microbiome,
• reduce unnecessary triggers,

the greater the chance that the atopic march will stop or be significantly reduced.

How can the atopic process be influenced?

The atopic march is not something that “has to happen.” It is a description of a common development, not an inevitable scenario. It is during childhood that we have the greatest opportunity to influence its course.

The following helps to alleviate or stop it:

• elimination–exposure diet, which helps to uncover real triggers while supporting the return of tolerance,
• working with food allergens– targeted, gradual introduction of allergens back into the diet,
• reduction of chemical loadin the household (detergents, cosmetics, cleaning products),
• support for the intestines, immunity and overall body load.

It is the combination of these steps that makes the most sense – not suppressing symptoms, but addressing the causes.

This application is designed to guide you through this process step by step - from the first suspicions, through working with allergens to long-term calming of the body. With a properly guided procedure, the atopic process can be significantly reduced or, in some cases, completely stopped.

Summary

• Eczema triggers change over the years.
• In babies, diet dominates, in older children, environment and stress.
• The atopic march describes the typical but controllable development of allergic diseases.
• Early work with diet and triggers can fundamentally change its course.
