Study indicates obesity may be linked to severity of psoriasis symptoms.
(1/23, McDermid) reported that the results of a study published in the
Journal of Dermatological Science
"strengthen the link between obesity and severity of psoriasis symptoms." In the study, patients' Psoriasis Area and Severity Index (PASI) "scores correlated positively with...three measures of obesity," body mass index (BMI), percent body fat, and visceral adiposity. Notably, they found "the strongest correlation" in visceral adiposity. The researchers wrote that "increased visceral adiposity increases the secretion of tumour necrosis factor (TNF)-α and interleukin (IL)-6, which might play an important role on the induction and the maintenance of psoriasis."
