Allergic dermatitis in infants – causes and treatment

Dermatitis in newborns appears quite often, because it is scary to even imagine how many foreign substances, various microbes await us around.

Protection and guarantee of a quiet life is our immunity, which does not allow us to break the constancy of the internal environment and rage it inside us. But even in this practically perfect mechanism there are failures when an inadequately strong reaction develops to a small, harmless impact from the outside.

Reasons for the appearance

Let’s try to imagine a small newborn child who has spent so much time in a sterile, comfortable environment. His immunity has just begun to work, his mother supplied him with some of the necessary antibodies. When faced with unknown factors, an imperfect protection system can often make a mistake and take quite ordinary, everyday things for a danger. Allergic dermatitis is especially likely if the family has patients with bronchial asthma or other similar diseases.

At the same time, the amount of immunoglobulin E in the child’s body increases, it begins to accumulate under the skin and mucous membranes in special cells. Cells react to it, throwing biologically active substances into the surrounding space that damage tissues. There are quite a few of these compounds, but the most famous of them is perhaps histamine. That is why the main manifestations of allergies are damage to the skin and organs where there are mucous membranes (nose, mouth, respiratory tract, stomach and intestines).

Since most of the allergens in babies are food, proper functioning of the digestive system will help to avoid or at least reduce such pathological processes. New baby organs should get to know the products gradually so that they do not become overloaded. Otherwise, many toxins are formed inside the intestines, which the liver and kidneys are not able to neutralize. Being in the blood for a long time, they irritate the immune system and lead to a worsening of the condition.


Most often, dermatitis spreads over the face, on the limbs, their extensor surfaces, less often on the trunk. A rash appears in the form of separate specks covered with a scab. The skin becomes wet, crusted, becomes dry, thickened, reddened. The child suffers from itching, he becomes irritated, nervous, does not sleep well, refuses to eat. The situation is aggravated by teething, adding a new type of food to food.


If the disease is not treated at this stage, microbes, of which there are many around, begin to multiply on the wet damaged surface. A secondary infection, purulent complications join. In addition, the constant imbalance between different parts of the immune system leads to the development of other types of allergies, including bronchial asthma.

A sick baby needs special care to protect him from harmful substances. Use gentle hypoallergenic lotions, detergents, soft towels, which you need to gently blot the skin with. To reduce the chlorine content in water, it is defended or filtered in advance. Clothes are selected from natural fabrics, loose fit, without rough seams.

Much attention is paid to nutrition. New dishes are added gradually, avoiding products known for their allergenicity. Various preservatives, dyes, taste improvers are strictly prohibited. For such children, it is better to cook porridge, fruit juices and mashed potatoes on their own, and not buy ready-made ones in the store.

More attention and care will certainly pay off with the health of the child and the good mood of the parents.
