Irritable Bowel Syndrome and Eating Disorders: A Burgeoning Concern in Gastrointestinal Clinics

Gastroenterol Clin North Am. 2021 Sep;50(3):595-610. doi: 10.1016/j.gtc.2021.03.007.

Abstract

Irritable bowel syndrome affects 10% to 15% of the population, and up to 90% of patients with irritable bowel syndrome exclude certain foods to improve their gastrointestinal symptoms. Although focused dietary restrictions are a normal, adaptive response, restrictions can spiral out of control and result in maladaptive restriction. Dietary therapies are rapidly becoming first-line treatment of irritable bowel syndrome, and gastroenterologists need to be aware of red flag symptoms of maladaptive eating patterns and the negative effects of prescribing restrictive diets. There is also growing awareness of the association between eating disorders and gastrointestinal symptoms, including irritable bowel syndrome symptoms.

Keywords: ARFID; Disordered eating; Eating disorder; Irritable bowel syndrome; Orthorexia.
