This article will discuss the common causes and risk factors of dyshidrotic eczema. It will also cover how genetics and lifestyle choices play a factor in the development of the condition.
Common Causes
The cause of dyshidrotic eczema is not known, but what experts do know is that the condition is not contagious, and women are more likely than men to develop skin rashes. Specific triggers can cause the condition to appear.
Some triggers that can cause dyshidrotic eczema include:
Contact with metals: many of the items that people touch throughout the day have metal in them. This includes clothes, jewelry, and coins. Nickel is one of the more common triggering metals. Warm weather: as temperatures rise, some people find that the weather can trigger their dyshidrotic eczema. Stress: stress has been found to be a trigger. Preexisting allergies: people with allergies are more likely to have dyshidrotic eczema than those without allergies. Wet hands: frequently damp hands can trigger the rash. Shampoos and soaps: certain shampoos and soaps may irritate the skin, triggering dyshidrotic eczema.
A healthcare provider can help identify a person’s triggers. Though not all triggers can be avoided, many of them can. Staying away from triggers can reduce the likelihood of developing the rash.
Lifestyle Risk Factors
Lifestyle risk factors for dyshidrotic eczema are factors that a person has control over. These include:
Exposure to allergens and irritantsSmokingUltraviolet light exposure
A few risk factors that are not always avoidable are atopic dermatitis, hyperhidrosis (excessive sweating), and receiving intravenous immunoglobulin therapy.
Summary
Dyshidrotic eczema is a rash that develops on the hands and feet. It causes itchy, fluid-filled bumps that occasionally appear or come and go. As they start to heal, the bumps form a red, scaly patch on the skin. Experts do not know what causes this, though they have identified several triggers, such as contact with metals, wet hands, and stress.
A Word From Verywell
Dyshidrotic eczema can interfere with your life and work. The bumps it forms on your hands and feet are intensely itchy and can become infected if scratched open. It’s important to work with your healthcare provider to identify your triggers. Eliminating or minimizing your exposure to them can reduce the incidence of the rash.
