AbstractObjectiveThe increasing global prevalence of obesity, coupled with its association with chronic health conditions and rising healthcare costs, highlights the need for effective interventions; however, despite the availability of treatment options, the ongoing success of primary interventions in maintaining long‐term weight loss remains limited. This study examined the prescription medication dispensing changes following sleeve gastrectomy in Australians aged 45 years and over.MethodsIn a retrospective analysis of 847 bariatric surgery patients from the New South Wales 45 and Up Study, the assessment of medication patterns categorizing into three groups: gastrointestinal, metabolic, cardiorespiratory, musculoskeletal, and nervous systems was conducted. Each drug class was analyzed, focusing on patients with dispensing records within the 12 months before surgery. This study employed interrupted time‐series analysis to compare pre‐ and post‐surgery medication usage.ResultsWith a predominantly female population (76.9%) and an average age of 57.2 (standard deviation 5.71), there were statistically significant reductions in both unique medications (12.5% decrease, p = 0.004) and total medications dispensed (15.9% decrease, p = 0.003) from 12 months before surgery to 13–24 months after bariatric surgery. All medication categories, except opioids, showed reductions. Notably, the most significant reductions were observed in diabetes (38.6%), agents acting on the renin‐angiotensin system (40.4%), lipid modifying agents (26.5%), anti‐inflammatory products (46.3%), and obstructive airway diseases (53.3%) medications during this time frame.ConclusionThese findings suggest that sleeve gastrectomy provides an effective therapeutic intervention for patients with comorbidities requiring multiple medications, especially for obesity‐related diseases such as diabetes, cardiovascular, respiratory and musculoskeletal disorders.
