Abstract

SUBJECT: In view of the epidemic increase in severe obesity and the ineffectiveness of conservative weight-loss interventions, bariatric surgery delivers compelling results for patients with class II (BMI ≥ 35 kg/m²) and class III obesity (BMI ≥ 40 kg/m²), not only in reducing weight over the long term, but also in reducing obesity-related somatic comorbidity and improving psychosocial functioning and quality of life. Investigations into the psychosocial aspects of obesity surgery have proliferated over the last 15 years, providing a huge amount of essential research data. Yet the results are partly contradictory and highly dependent on the duration of follow-up.
METHODS: Based of a narrative review, this article provides an overview of the current status and recent developments of the reciprocal effects between bariatric surgery and psychosocial functioning. The review focused on eight domains representing important psychosomatic and psychosocial aspects of bariatric surgery.
RESULTS: Especially in cases of class II and III obesity, bariatric surgery is the only means to reduce bodyweight significantly and permanently, though they carry with them the associated risk factors of metabolic, cardiovascular, and oncological diseases.With regard to psychosocial and psychosomatic aspects, studies with a short-term catamnesis (approx. 3 years) speak in favor of an improvement in the quality of life including mental disorders. If we consider studies with longer follow-ups, however, the results are not as uniform. In particular, we observe an increase in harmful alcohol consumption, self-harm behavior, and suicide risk.
CONCLUSIONS: In light of mental well-being and thus also quality of life, bariatric surgery would appear to convey an elevated risk for a minority of patients.Yet identifying these patients before surgery has so far been insufficient.
