Is eczema hereditary?

In general, whether eczema is hereditary depends on specific circumstances. Most cases of eczema are not inherited; however, in rare cases, inheritance may occur if there is a clear familial clustering. Detailed analysis is as follows:

The occurrence of eczema may be related to allergic factors, unhealthy lifestyle habits, and individual physical conditions, rather than necessarily being directly associated with family genetics. If eczema is caused by external factors such as living environment, dietary habits, or allergens, and there are no family members with the condition, it typically will not be inherited.

If the eczema is atopic dermatitis or shows a clear familial clustering, it may be hereditary. Atopic dermatitis is a type of eczema with a typical family genetic history, which may lead to weakened skin barrier function, making the skin more susceptible to external irritants and allergens, thus triggering eczema. It may also be accompanied by allergic rhinitis, allergic conjunctivitis, or allergic asthma. In such cases, appropriate medications should be used under the guidance of a physician for targeted treatment.

It is important to maintain clean and moisturized skin, avoid excessive friction and scratching, and pay attention to both personal and family medical history. Adjusting living conditions and dietary habits appropriately can help reduce the risk of eczema.
