The prevalence of underweight is increased in chronic pancreatitis outpatients and associates with reduced life quality.

Background: Underweight is a well-known complication of chronic pancreatitis (CP), but little is known about its prevalence in the outpatient setting. We investigated the prevalence of underweight in outpatients with CP and its association with quality of life (QOL) and various risk factors.

Methods: This was a cross-sectional study of 166 outpatients with CP that was conducted at a tertiary referral center.
