Discontinuation of blood pressure-lowering, glucose-lowering, and lipid-lowering medications following bariatric surgery: A nationwide cohort study in South Korea
Surgery for Obesity and Related Diseases(2024)
Abstract
Background
Limited evidence exists on the pattern of medication use for hypertension, diabetes mellitus (DM), and dyslipidemia after bariatric surgery among Asian patients.
Objective
To investigate the pattern in the use of blood pressure-lowering-, glucose-lowering-, and lipid-lowering medications following BS in Korean patients with morbid obesity.
Setting
This study is a retrospective cohort study using the Health Insurance Review and Assignment claims database of South Korea (from 2019 to 2021).
Methods
We included patients who underwent BS between 2019 and 2020 in South Korea. We evaluated the treatment pattern of blood pressure-lowering-, glucose-lowering-, and lipid-lowering medications at 3-month intervals for 1-year following BS, including medication use, individual medication classes, and the number of medications prescribed. Further, we estimated remission rates for each disorder based on patient characteristics by defining patients who discontinued their medications for at least two consecutive quarters as remission.
Results
A total of 3,810 patients were included in this study. For 1-year following BS, a marked decrease in the number of patients using blood pressure-lowering-, glucose-lowering-, and lipid-lowering medications was observed. The most remarkable decrease occurred in glucose- lowering medications, which decreased by approximately −75.1% compared with that at baseline. This tendency was consistently observed when analyzing both the number of medications prescribed and the specific medication classes. Regarding remission rates, patients who were female, younger, and received the biliopancreatic diversion-duodenal switch as their BS showed a relatively higher incidence of remission than other groups.
Conclusion
BS was associated with a decrease in the use of medications for hypertension, DM, and dyslipidemia.
