Psychological adaptation to jejunoileal bypass for morbid obesity.

Psychological adaptation to jejunoileal bypass procedures in 34 morbidly obese patients was evaluated preoperatively and followed postoperatively for an average of 23 months. Preoperative emotional disturbances were mainly those of mild personality disorders with passive-aggressive, passive-dependent, and emotionally immature traits. Following discharge from the hospital, nine patients (or 24 per cent) developed psychiatric difficulties, characterized by either increased neurotic symptoms and interpersonal problems, or the emergence of psychosis. Male patients and those with the greatest weight loss were statistically more likely to have psychiatric complications. The remaining patients expressed satisfaction with the operation, noted relief from the burden of dieting, experienced less excitement associated with eating, and felt more self-confident and hopeful.
