BACKGROUND: This study was conducted to assess the impact of abdominoplasty and lower body lift surgery following massive weight loss on both the general quality of life and the sexual life of patients. METHODS: We performed a multicenter prospective study on the quality of life after massive weight loss using three scoring questionnaires: The Short Form 36 questionnaire, the Female Sexual Function Index questionnaire, and the Moorehead-Ardelt Quality of Life Questionnaire. Seventy-two patients who underwent lower body lift and 57 patients who underwent abdominoplasty in three centers with pre and post-operative evaluation were included. RESULTS: The mean age of the patients was 43.2 ± 13.2 years. All categories of the SF36 questionnaire were statistically significant at 6 months, and all categories except health change were significantly improved at 12 months post-operative. Overall, the Moorehead-Ardelt questionnaire showed a higher quality of life in general (1.78 ± 0.92 and 1.64 ± 1.03, at 6 and 12 months respectively) and in all domains (self-esteem, physical activity, social relationships, work performance, and sexual activity). Interestingly, global sexual activity improved at 6 months but not at 12 months. Some domains of sexual life improved at 6 months (desire, arousal, lubrication, satisfaction), but only the desire stayed improved at 12 months. CONCLUSION: Abdominoplasty and lower body lift improve the quality of life of patients after massive weight loss as well as the sexual quality of life. This should be an additional valid reason for promoting reconstructive surgery for massive weight loss patients.
