Baseline Stomach Volume and Normal Meal Capacity
Placeholder: healthy stomach capacity before any device is placed.
- ~1,200 mL: Functional capacity (placeholder typical adult range)
- ~75 mL: Empty resting volume (placeholder collapsed state)
- 100%: Meal size baseline (placeholder reference portion)
- ~4 hrs: Gastric emptying (placeholder solid meal average)
Stomach as a distensible reservoir
Placeholder: stretch receptors signal fullness once volume rises.
Candidacy for volume-based therapy
Placeholder: moderate obesity, surgery-averse patients considered first.
Balloon Insertion — Deflated Delivery, In-Situ Saline Inflation
Placeholder: outpatient endoscopic procedure, no incisions required.
- ~20–30 min: Procedure time (placeholder outpatient sedation)
- 300–700 mL: Fill volume range (placeholder saline + dye)
- 0: Incisions required (placeholder transoral delivery)
- 1–2 days: Recovery time (placeholder typical adjustment)
Transoral catheter delivery
Placeholder: deflated balloon guided down the esophagus under sedation.
In-stomach saline inflation
Placeholder: balloon filled with saline and marker dye endoscopically.
Reduced Effective Stomach Capacity While the Balloon Sits in Place
Placeholder: balloon volume directly displaces available meal space.
- 40–60%: Capacity remaining (placeholder depends on fill size)
- Earlier: Stretch-receptor trigger (placeholder reduced volume needed)
- Lower: Portion tolerance (placeholder smaller meals fit)
- Modest ↑: Reflux risk (placeholder monitored clinically)
Physical volume-displacement mechanism
Placeholder: less empty space means fullness cues arrive sooner.
Balloon type and fill considerations
Placeholder: larger fill volumes displace more space, more discomfort.
Early Satiety, Smaller Meals, and Accruing Weight Loss Over Six Months
Placeholder: smaller portions sustained across the indwelling window.
- 6 months: Indwelling duration (placeholder standard protocol)
- 8–18%: Average weight loss (placeholder of body weight)
- 30–70%: Meal size reduction (placeholder vs baseline portion)
- Recommended: Adjunct coaching (placeholder diet/behavior support)
Satiety-driven behavior change
Placeholder: repeated small-meal cues help reshape eating habits.
Tracking progress during treatment
Placeholder: weight trend logged monthly alongside dietary coaching.
Balloon Removal at Six Months — Durability Depends on Habits Formed
Placeholder: balloon extracted endoscopically; long-term results vary by habits.
- Endoscopic: Removal method (placeholder deflate then extract)
- Faster: Weight regain (no habits) (placeholder reverts toward baseline)
- More durable: Weight maintained (habits) (placeholder sustained routines)
- 6 months: Total indwelling time (placeholder device removed on schedule)
Endoscopic extraction procedure
Placeholder: balloon deflated, grasped, and withdrawn transorally.
What determines long-term durability
Placeholder: habits formed during treatment predict post-removal trend.
Placeholder highlight: sustained habit change outweighs the device itself.
