Adherence

Patients who transfer hospitals for secondary MBS are significantly younger, have fewer obesity-related comorbidities (hypertension, GERD), and are more likely to undergo secondary surgery for recurrent weight gain compared to those who stay.

If you are younger and generally healthy but are experiencing weight regain after your first bariatric surgery, you are part of a common group that seeks a second opinion or a different surgeon for revisional surgery. This is often driven by dissatisfaction with the amount of weight lost rather than medical complications.

GoodSupportsHIGH confidence
At baseline, these patients on average were younger (37.9 vs. 42.5, p < 0.001), less often had hypertension or GERD... At secondary surgery... the indication was more often recurrent weight gain (49.0% vs. 23.0%, p < 0.001).
