Study of the Effect of Diet in Overweight or Obese Patients With Psoriasis on Light Therapy

Completed · Not applicable

Conditions studied: Psoriasis, Weight Loss, Diet

In brief

The association between psoriasis and obesity has been questioned by physicians for many years. Studies have shown that the risk of having psoriasis is increased in people with a high body mass index, which is a measurement of obesity. There have been case reports of remission of psoriasis after gastric bypass surgery. Furthermore, other studies have shown that certain inflammatory diseases (such as rheumatoid arthritis) can be improved by dietary changes. The purpose of this study is to assess whether a low carbohydrate or low fat diet can be helpful in the treatment of psoriasis.
