Abstract:
Obesity is associated with psoriasis and poses a significant obstacle to psoriasis management. Bariatric surgery is an effective procedure for weight loss, and some reports suggest that it may improve psoriasis. However, more evidence is needed before definitive conclusions can be drawn. Bariatric surgery procedures, in particular the Roux-en-Y gastric bypass, may one day be a viable option for obese patients with refractory psoriasis.
