Primary hypothesis: As compared to non-surgical treatment, bariatric surgery will be associated with higher rates of remission, and lower rates of new-onset drug treated hypertension during a follow-up period of ≤ 10 years.\n2. Secondary hypotheses: Changes in the usage of other drugs, particularly drugs related to obesity related comorbidities, will differ significantly between patients undergoing bariatric surgery or non-surgical treatment during the follow-up period. </p><br/><p><b>Study Design:</b> Observational research (coded as: SEVCO:01002 from https://fevir.net/sevco); Parallel cohort design (coded as: SEVCO:01011 from https://fevir.net/sevco); Longitudinal data collection (coded as: SEVCO:01028 from https://fevir.net/sevco)</p></div>"
