Patients with severe obesity and Type 2 Diabetes experience a greater reduction in all-cause mortality from bariatric surgery compared to those with severe obesity alone.

If you have severe obesity and Type 2 Diabetes, bariatric surgery offers an even greater survival benefit than for those with obesity alone. This makes it a particularly strong consideration for managing your health and longevity.

The subgroup analysis for T2D status showed that patients with T2D who had undergone bariatric surgery had a pooled HR of all-cause mortality of 0.49 (95% CI: 0.45–0.54, P < 0.001, I2 = 0%) compared with matched nonsurgical subjects, and patients without T2D who had undergone bariatric surgery had a pooled HR of all-cause mortality of 0.68 (95% CI: 0.57–0.82, P < 0.001, I2 = 0%) compared with matched nonsurgical subjects. The difference between the T2D subgroup and no T2D subgroup was statistically significant (heterogeneity between subgroups: P = 0.001, I2 = 90.5%, Fig. 4).
