Gastric bypass surgery can improve psychiatric behaviours

Bariatric surgery can results in improvements in patients’ psychiatric behaviours such as eating behaviours, mood disorders and body image, although the mechanism as to why is not clear, according to a study by Portuguese researchers. Published in the Archives of Clinical Psychiatry (São Paulo), the paper ‘A psychiatric perspective view of bariatric surgery patients’, states that despite these improvements clinicians should be aware that a risk of suicide and substance abuse (especially alcohol) after gastric bypass surgery remain in some patients.

AMOS: Gastric bypass benefits most adolescents

Teenagers suffering from severe obesity generally feel worse than their peers, but after undergoing gastric bypass nearly all experience improved mental health. One in five, however, still suffers from symptoms of depression - some quite seriously. These are the results of a study, ‘Two-year trends in psychological outcomes after gastric bypass in adolescents with severe obesity.’ from Lund University in Sweden, published in Obesity.

Most bariatric patients have at least one mental disorder

According to a study carried out by researchers in Germany 84% of the patients seeking bariatric treatment screened positive for at least one mental health disorder. Utilising a computerised Patient Health Questionnaire (PHQ), the researchers from RWTH Aachen University Hospital and St Elisabeth Hospital Geilenkirchen, Germany, found that the automated reporting system “appears to be a useful instrument for pre-surgical assessment of bariatric patients in routine medical settings”.

Psychological factors prevent patients completing surgery

Many bariatric surgery candidates often drop out of the surgical process because they experience surgical anxiety and/or they believe that they can lose weight on their own, without surgery, according to research by investigators led by Dr David Mahony from PsyBari, Brooklyn, New York, US. Although these obese patients present with co-morbidities, these conditions do not sufficiently motivate patients to complete the surgical process.

Obesity could be evidence of psychosomatic disorders

There is evidence that morbidly obese patients could suffer from psychosomatic disorders, according to a study, published in the journal Psychotherapy and Psychosomatics. However, the results suggest that these syndromes are not specifically linked to obesity.
