Description
Katharina Helena Morawitz and colleagues report a 2026 study of biological age after bariatric surgery. Bariatric surgery, weight loss surgery, cuts body weight a lot, yet health gain in the first two years was less studied. The team modelled mortality associated biological age from standard blood markers. Age acceleration is the gap between biological and calendar age. A prospective cohort of five hundred five surgery patients was tracked to two years.
At baseline, age acceleration rose with smoking load and with body mass, most in males. Twelve months after surgery, patients scored on average about five and a half years younger in biological age. The gain held stable to twenty four months. After adjustment for body mass change, the gain shrank to about three and a third years at twelve months. Part of the rejuvenation thus runs apart from weight loss itself, a gain the authors call independent in the title.
