Summary

It is important for members of the multidisciplinary team to work together for the best outcome for the patient. For the same reasons, we have been organising a joint session at the  ANZOS conference with the National Association for Clinical Obesity Services (NACOS) as well as the Australian and New Zealand Obesity and Metabolic Surgery Society (ANZMOSS), to ensure the attendees get to hear collective views and different perspectives. This year, we look forward to hearing different perspectives on predicting response following bariatric surgery from A/Prof Samantha Hocking, President of NACOS and Jacob Chisholm, President of ANZMOSS. We are also delighted to have Janet Franklin bringing the dietitian’s perspective and Andrew Wilson, Board Member of Weight Issues Network (WIN) highlighting weight stigma and talking about lived experience. This session will explore whether you could predict how well a person will do after surgical weight loss from a medical, dietetic and surgical perspective. Presentations will include pre-operative and post-surgical factors, biomarkers and behavioural factors, and whether it is possible to identify responders and non-responders to surgical weight loss before surgery in terms of weight loss and complication remission? We look forward to having a panel discussion for the last half hour of this session to allow time for a healthy discussion and exchange of views.

PCOS affects up to 13% of women with reproductive, metabolic and psychological features. Lifestyle interventions (diet, exercise and behavioural) for weight management are recommended first-line therapy in prior (2018) International Evidence-based Guideline for Assessment and Management in PCOS. The guidelines have recently been updated using world’s best practice processes involving 61 guideline development group members, a senior steering committee from 7 continents and collaboration with 37 international societies. A large number of systematic reviews were undertaken, which guided over 100 recommendations and practice points and full AGREEII and GRADE were applied across Lifestyle interventions, Diagnosis and screening, Emotional wellbeing and Models of care, Pharmacological therapy and Infertility management. The key updates and recommendations and co-developed translation and dissemination strategies will be presented for the Lifestyle Guideline Development Group. These will cover the key Lifestyle Guideline group topics of effectiveness of lifestyle management, behavioural interventions, dietary interventions, exercise interventions, increased risk of weight gain and weight stigma.
