Peters JE, Basnayake C, Hebbard GS, et al. - Findings demonstrated a high prevalence of disordered eating among adult patients suffering from gastrointestinal illness, especially those with disorders of gut-brain interaction (DGBI).

• In this systematic review, studies investigating disordered eating in adult patients with a primary gastrointestinal diagnosis were identified from MEDLINE, PubMed, and PsycInfo databases.

• Eligible 17 studies were included which revealed that disordered eating prevalence ranged from 13–55%.

• A higher prevalence was evident in patients with DGBI compared with those suffering from organic gastrointestinal disorders.

• Female gender, younger age, gastrointestinal symptom severity, anxiety and depression, and lower quality of life were the factors that were related to disordered eating.

• It is a challenge for clinicians to ascertain if a patient's primary underlying diagnosis is that of an eating disorder or gastroenterological disorder.

• An unmet need to detect at-risk cases is still there, so that psychological intervention can be incorporated in the treatment strategy.
