Some studies of children and young people with atopic eczema found that one-third to nearly two-thirds also had a food allergy. Having a food allergy increases the likelihood of your atopic eczema being severe.
Allergies do not always play a role. There are many other things likely to bring out eczema, including: cold weather, dampness, harsh soaps, washing too much and rough clothing.
Triggers can make atopic eczema worse, although they do not necessarily cause the condition. Hormones are also powerful chemicals that are produced by the body and have a wide range of effects. Changes in the levels of certain hormones can affect the symptoms of atopic eczema in some women.
Many women’s eczema is worse at certain times during their menstrual cycle. Some women have a flare-up of their eczema in the days before their period.
The hormonal changes during pregnancy can also affect atopic eczema: more than half of all pregnant women find their symptoms get worse, one-quarter of pregnant women find their symptoms improve.
While stress is known to be associated with atopic eczema, it is not fully understood how it affects the condition. Some people with eczema have worse symptoms when they are stressed. For other people, their symptoms cause them to feel stressed.
