Our aim is to help patients lose between 60 – 100% of their excess weight (that is, the number of extra kilograms you are carrying over a BMI of 25). The final goal weight you reach depends on several factors including your build, body composition, sex and age. It also depends on how successful you have been in changing your dietary behaviours, lifestyle, and physical activity levels after surgery. The reason why we set a minimum goal of achieving 60% excess weight loss is because this level of weight loss will lead to maximal improvement in any weight-related co-morbidities. In general, most patients having the sleeve gastrectomy will reach their goal weight by 12 months.
