What’s New in Eczema (atopic dermatitis)

Eczema (atopic dermatitis) - Dr. Chiang | Magan Clinic

Many skin diseases are ignored and dismissed by both patients and providers because it’s “just the skin.” However, research has shown an increasing understanding that simply having some skin diseases increases the risk of internal side effects. The evidence has been strongest for psoriasis which has been linked to metabolic syndrome including diabetes, high blood pressure, elevated cholesterol, and obesity. It also increases the risk of coronary artery disease. Thus, patients are at elevated risk for heart disease and stroke. Thankfully, treatment of moderate to severe psoriasis may decrease these risks.

More recently, studies have shown that children with eczema (atopic dermatitis) are also at risk for internal side effects, especially elevated blood pressure and obesity. In addition, there is an elevated risk of mental health issues including depression, anxiety, conduct disorder, and autism that increases with the severity of skin disease. In addition, female teenagers may have an increased risk of suicidal behavior.

If you wish help in improving your skin disease or have any other skin concerns, please make an appointment for dermatology consultation at (626) 331-6411.
