title: Pudendal nerve entrapment leading to avoidant/restrictive food intake disorder (ARFID): A case report.
abstract: Avoidant/restrictive food intake disorder (ARFID) is a diagnosis in diagnostic and statistical manual of mental disorders-5 (DSM-5) manifested by persistent failure to meet nutritional and/or energy needs. Pudendal nerve entrapment (PNE) often causes pelvic discomfort in addition to constipation and painful bowel movements. Current literature on ARFID is sparse and focuses on the pediatric and adolescent population. No association between PNE and ARFID has been described. We present a case of ARFID in an adult male with PNE resulting from subsequent scarring from testicular cancer surgery. The patient's gastrointestinal symptoms due to PNE caused significant food avoidance and restriction subsequently leading to severe malnourishment. Clinicians should be aware that distressing gastrointestinal symptoms arising from a secondary disease process such as PNE might lead to dietary restriction and food aversion. More research is needed for proper screening, detection, and treatment of ARFID. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:84-87).
