Clinical Implications

Taken together, although more and higher quality evidence is required on pharmacological and surgical weight loss interventions, these limited data support the role of proactive screening and treatment of obesity in patients with psoriasis and PsA, and highlight obesity as an important modifiable risk factor in the development of psoriasis. As obesity is an independent risk factor for other long-term conditions associated with psoriasis such as cardiovascular disease, weight loss also holds the promise of reducing overall extracutaneous morbidity. Achieving a healthy weight is thus a key treatment goal in psoriasis.
