Eczema is a form of dermatitis. “Itis” is the medical term for inflammation, and “derm” refers to the skin. Therefore, any skin inflammation is called dermatitis. However, eczema is most commonly associated with atopic dermatitis, an allergic condition closely linked to asthma and hay fever.

Eczema often runs in families, and the risk is higher if one parent is affected, with a significantly higher risk if multiple family members have it. It usually starts in infancy. Fortunately, while one in five children may develop eczema, two-thirds will outgrow it by their mid-teens.

Genetics play a significant role, with a three in five chance of developing eczema if one parent has it and a four in five chance if both parents are affected. In cases of eczema, the oily protective layer of the skin is reduced.

The exact reason why one child may be affected while another is not remains unclear. Factors like pollution, climate change, and diet might play a role. It is well-known that food allergies, such as cow’s milk allergy in babies, can be a common cause of eczema.

These food allergies often come with other symptoms. If there is any doubt, it is advisable to refer to information on the cow’s milk protein allergy.
