What’s New in Eczema (atopic dermatitis)


Eczema has been increasingly associated to cardiac risk factors. The first is obesity. As the prevalence of eczema has been increasing in the past few decades (up to 20% of children and 10% of adults), a research review concluded it may be related to the increasing prevalence of obesity worldwide. This would make sense as eczema is partially a disease of a dysfunctional immune system, overactive in some ways, underactive in other ways. Obesity does result in a chronic low-grade inflammation that would theoretically worsen eczema. Overall, the, the analysis did indeed find a modest association between being overweight/obese and an increased prevalence and severity of eczema. As a side note, I am often asked if there is any diet that would improve eczema. I am not aware of one, but healthy weight loss should help.

In addition, separate studies found that eczema increased the odds of hypertension and prediabetes. This may be intrinsic to eczema itself. It may also be partially due to increased rates of alcohol usage and smoking along with decreased exercise activity found in population studies of patients with eczema. These poor health habits may be secondary to the increased stress of having itchy skin and visible rashes along with poorer heat tolerance (ie, poor sweating).

If you or your child has eczema, of whatever severity, I look forward to seeing you. Hopefully optimal management of the eczema will decrease the risks of obesity, hypertension, and prediabetes. Please make an appointment for a dermatology consultation at (626) 331-6411.
