Bariatric Surgery for Resistant Hypertension: Working in Progress!

Purpose of ReviewTo discuss the recent evidence pointing the benefits of the bariatric surgery on blood pressure control in patients with obesity and hypertension. Particular focus is devoted to discuss the potential impact on resistant hypertension.Recent FindingsGrowing evidence suggest that bariatric surgery promotes not only a significant reduction in the anti-hypertensive medication while maintained blood pressure control but also a significant proportion of hypertension remission as compared to the usual care. In a sub-analysis of the GATEWAY trial using both office and 24-h ambulatory blood pressure monitoring, the prevalence of resistant hypertension significantly decreased after 12 months in the surgical group whereas the numbers remained stable in the control group.SummaryDespite the lack of robust evidence, preliminary findings underscore the strong need to explore the potential role of bariatric surgery on resistant hypertension in patients with obesity. This statement is justified not only for the burden of obesity in this scenario but also for the unmet demands in managing resistant hypertension appropriately by multiple drug-therapy or the lack of real utility of procedures like renal denervation and carotid baroreflex activation.
