Obesity surgery: dietary and psychosocial expectations and reality.

: Psychosocial and dietary habits have been compared in patients considering (Pre n = 33) or who had (Post n = 32) surgery for morbid obesity. Failure of conventional diets was attributed to lack of self-discipline (Pre 92% [22/24] vs. Post 87% [20/23], NS). Consumption of fast foods fell (Pre 70% [23/33] vs. Post 16% [5/32], p < 0.0001). Preoperative patients had unrealistic social expectations. They exaggerated the prospect of improved friendship (Pre 67% [22/32] vs. Post 34% [11/21], p < 0.05), erroneously anticipated better sex (Pre 78% [25/32] vs. Post 50% [15/30], p < or = 0.05), predicted better acceptance at work (Pre 85% [23/27] vs. Post 50% [15/30], p < or = 0.05), and misanticipated improved relationship with their partner (Pre 77% [20/26] vs. Post [47% 8/17], p < or = 0.05). Two factors predicted becoming employed following surgery: age (became employed [n = 5] 28 +/- 2 years vs. remained unemployed [n = 12] 44 +/- 4 years, p < 0.05) and percentage of excess weight lost (became employed 76 +/- 11 vs. remained unemployed 51 +/- 7, p < 0.05). The free support group was "useful" (17/17), yet only 5% attended regularly. Patients considering obesity surgery had specific unrealistic psychosocial expectations. They infrequently availed themselves of postoperative professional help. We identify the features associated with gaining employment.
