Abstract Psoriasis is a chronic inflammatory skin disease that is associated with obesity and myocardial infarction. Obesity‐induced changes in lipid metabolism promote T helper 17 (Th17) cell differentiation, which in turn promotes chronic inflammation. Th17 cells have central roles in many inflammatory diseases, including psoriasis and atherosclerosis; however, whether treatment of obesity attenuates Th17 cells and chronic inflammatory diseases has been unknown. In this study, we found an increase in Th17 cells in a patient with obesity, type 2 diabetes and psoriasis. Furthermore, weight loss with diet and exercise resulted in a decrease in Th17 cells and improvement of psoriasis. This case supports the hypothesis that obesity leads to an increase in Th17 cells and chronic inflammation of the skin and blood vessel walls, thereby promoting psoriasis and atherosclerosis.
