Obesity is present in as many as 45% of patients with psoriatic arthritis and is associated with increased disease activity and decreased treatment response. Data suggest that overweight and obese patients are less likely to achieve sustained minimal disease activity compared with patients of normal weight. A recent study showed that weight loss can improve preexisting psoriatic arthritis.

IBD is not the most common comorbidity associated with psoriatic arthritis, but patients with psoriatic arthritis have been found to have an increased risk for IBD as well as subclinical bowel inflammation. The presence of IBD is an important consideration that may influence treatment choice.

A recent study found that patients with psoriatic arthritis were 43% more likely to develop diabetes than people in the general population, even after controlling for obesity.

Patients with psoriatic arthritic have an increased incidence of nonalcoholic fatty liver disease and liver abnormalities. Patients with psoriatic arthritis and nonalcoholic fatty liver disease may not be able to attain minimal disease activity levels.
