Energy balance
Post-operative weight regain is a common long-term risk associated with bariatric surgery, driven by reduced energy expenditure and hormonal changes, requiring lifestyle adherence.
Expect that weight maintenance requires ongoing effort. Monitor your weight, adhere to dietary guidelines, and stay active, as biological changes (like reduced energy expenditure) can promote regain if lifestyle habits slip.
