Gastrointestinal symptoms and disorders in patients with eating disorders

Open access
Sato, Yasuhiro, Fukudo, Shin·2015·Clinical Journal of Gastroenterology

Abstract

The two most clinically serious eating disorders are anorexia nervosa and bulimia nervosa. A drive for thinness and fear of fatness lead patients with anorexia nervosa either to restrict their food intake or binge-eat then purge (through self-induced vomiting and/or laxative abuse) to reduce their body weight to much less than the normal range. A drive for thinness leads patients with bulimia nervosa to binge-eat then purge but fail to reduce their body weight. Patients with eating disorders present with various gastrointestinal disturbances such as postprandial fullness, abdominal distention, abdominal pain, gastric distension, and early satiety, with altered esophageal motility sometimes seen in patients with anorexia nervosa. Other common conditions noted in patients with eating disorders are postprandial distress syndrome, superior mesenteric artery syndrome, irritable bowel syndrome, and functional constipation. Binge eating may cause acute gastric dilatation and gastric perforation, while self-induced vomiting can lead to dental caries, salivary gland enlargement, gastroesophageal reflux disease, and electrolyte imbalance. Laxative abuse can cause dehydration and electrolyte imbalance. Vomiting and/or laxative abuse can cause hypokalemia, which carries a risk of fatal arrhythmia. Careful assessment and intensive treatment of patients with eating disorders is needed because gastrointestinal symptoms/disorders can progress to a critical condition.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
