Gastrointestinal dysfunction in Chinese patients with fat-phobic and nonfat-phobic anorexia nervosa

Although gastrointestinal and other somatic symptoms are common in patients with anorexia nervosa (AN), and a growing cross-national literature indicates that not all anorexic patients exhibit the core diagnostic symptom of fat phobia, the relationship between somatic symptoms and anorexic illness remains unclear. Our objective was to evaluate gastrointestinal dysfunction (GD) in Chinese patients with fat phobic (FP) and nonfat phobic (NFP) anorexia nervosa. A total of 113 FP- and 28 NFP-AN outpatients underwent standardized clinical assessment and completed a new 8-item GD scale and other psychopathological measures. A majority (79.4%) of AN patients reported at least some gastrointestinal complaints on the GD scale (Cronbach's alpha = 0.78). FP-AN patients scored significantly higher than NFP-AN patients. The FP-AN with high GD group reported a higher level of specific and general psychopathology than the FP- and NFP-AN with low GD groups. Contrary to expectations, gastrointestinal symptoms were more common in FP-AN than NFP-AN patients. FP-AN with high GD was more severe than FP- and NFP-AN with low GD. The current fat phobic conceptualization of the anorexic illness may overlook its phenomenologic heterogeneity and reify a dichotomy that is inconsistent with patients' varied experience of food restriction
