Bariatric Surgery Tied to 22% Lower 5-Year Stroke Risk

atients with obesity who underwent bariatric surgery had 46% lower odds of stroke 1 year later, similar odds of stroke 3 years later, and 22% lower odds of stroke 5 years later, compared with matched control patients, in new research.

Michael D. Williams, MD, presented the study findings (abstract A002) at the annual meeting of the American Society for Metabolic & Bariatric Surgery.

The findings are “very good news,” even though the protection against stroke declined further out from the surgery, John D. Scott, MD, scientific program chair of the ASMBS meeting, told this news organization.

The investigators matched more than 56,000 patients with obesity who had bariatric surgery with an equal number of similar patients who did not have this surgery, from a large national insurance database, in what they believe is the largest study of this to date.

Surgery is an effective and durable method for weight loss. It also can improve comorbid conditions, particularly diabetes and hypertension.”The impact of bariatric surgery on remission of type 2 diabetes is well known, Williams noted, and other studies have reported how bariatric surgery affects the risk of major adverse cardiovascular events — a composite of stroke, myocardial infarctioncoronary artery disease, and all-cause death — including a study presented in the same meeting session.
