Gastric Balloon Before Bariatric Surgery — What Is Bridge Therapy?

2026-03-10 · 9 min read

Bariatric surgery (sleeve gastrectomy, gastric bypass) offers effective long-term results; however, not every patient is ready or eligible for surgery. The approach that fills this gap is known as "bridge therapy."


What Is Bridge Therapy?

Bridge therapy is a temporary intervention applied to prepare for bariatric surgery. The goals:

  1. Preoperative weight loss: A 5–10% body weight loss is targeted to reduce surgical risk.
  2. Metabolic improvement: A positive effect on blood sugar, blood pressure, and fatty liver.
  3. Behavioral change: Developing portion-control habits — improves postoperative adherence.

Advantages of the Allurion Balloon as a Bridge Therapy

Unlike traditional endoscopic balloons, the Allurion:

  • Requires no endoscopy → No sedation/anesthesia risk in the morbidly obese patient.
  • Placed in 15 minutes → The patient goes home the same day.
  • Digital monitoring → Your physician follows the process remotely, and adherence is high.

In Ienca et al.'s study of 1,770 patients, a mean 14.9% TBWL was documented (Obes Surg 2020, PMID: 32279182). Before bariatric surgery, this loss significantly reduces surgical risk and liver size.


Who Benefits from Bridge Therapy?

ProfileRole of Bridge Therapy
BMI 35–45, not ready for surgeryPreoperative weight loss + habits
Hepatic steatosis (fatty liver)Liver size reduction (hepatic shrinkage)
Wanting to reduce surgical riskMetabolic parameters are improved
Wanting to postpone the surgery decisionA temporary but effective solution
BMI 30–35, on the surgical borderlineAlternative or preparation

Bridge Therapy Protocol

Typical process:

  1. Joint evaluation with a bariatric surgeon
  2. Allurion Balloon placement (~15 min)
  3. Months 4–6: Weight loss + nutrition habits
  4. Natural excretion of the balloon at ~week 16
  5. Surgical readiness evaluation

In a multicenter retrospective study (2025, Obes Surg, PMID: 41037243), it was shown that IGB placement did not adversely affect post-bariatric outcomes and optimized the preparation period.


Bridge Therapy and Long-Term Outcomes

The one-year weight-maintenance data are also encouraging: in Caballero et al.'s study of 522 patients, it was documented that 95% of patients maintained at least part of their weight loss after the Allurion Program (Obes Surg 2025, PMID: 40676353).


Conclusion

With bridge therapy, bariatric surgery can become both safer and more effective. With its endoscopy-free design, the Allurion offers an option that can be applied even in high-risk patients.
