The intragastric balloon is the only bariatric procedure that doesn't cut, staple, or permanently rearrange anything. A deflated silicone balloon is placed in your stomach through an endoscope -- a camera down the throat, no incisions -- inflated with saline, and left there to take up space. It makes you feel full faster, eat smaller portions, and lose weight. Then, six to twelve months later, it comes out the same way it went in.
That simplicity is both the appeal and the limitation. The balloon produces real weight loss -- typically 20-35% of excess body weight -- but it produces less than surgical options, and whatever you lose comes back if you haven't changed your relationship with food by the time the balloon is removed.
How the procedure works
Placement
The procedure takes 20-30 minutes under conscious sedation -- not general anesthesia. An endoscope (a flexible tube with a camera) is passed through the mouth and into the stomach. The deflated balloon follows, is positioned under direct visualization, and inflated with 400-700 ml of sterile saline. The endoscope comes out, the balloon stays. Most patients go home the same day or after a brief observation period.
The first 3-5 days after placement are rough. Nausea, cramping, and vomiting are common as the stomach adjusts to the foreign object. Your programme should prescribe anti-nausea medication in advance -- if they don't mention this, ask.
Life with the balloon
Once the adjustment period passes, the balloon works by mechanical restriction. Your stomach has less room for food, so you eat less. But the balloon alone doesn't teach you what to eat or why you overeat -- that's the job of the nutritional and behavioural programme that should come bundled with placement.
Reputable programmes include monthly nutritionist consultations, dietary coaching, and sometimes psychological support throughout the balloon period. This isn't optional window dressing. The research is clear: patients who receive structured dietary support during the balloon period lose more weight and keep more of it off after removal than patients who get the balloon alone.
Removal
At 6 months (or 12 months for newer models), the balloon is deflated endoscopically and removed. Same sedation, same procedure, same recovery. The stomach returns to its original size within days.
And this is the moment of truth. If you've used the balloon period to build new eating habits, reduce portion sizes, and address the behavioural patterns that caused the weight gain -- you have a chance of maintaining the loss. If you haven't, the weight comes back. The literature is unambiguous about this.
The rebound problem
Published data shows that a significant proportion of patients regain most or all of the weight lost within 12-24 months of balloon removal. The balloon is a tool, not a treatment -- it creates a window of opportunity, but it doesn't close the window behind you. Any programme that doesn't talk about the post-removal plan before placement is selling a device, not a solution.
Who the balloon is actually for
Good candidates
- BMI 30-40 who don't qualify for or don't want surgery. The balloon fills the gap between "diet and exercise" and "operating room."
- Patients who need to lose weight before another procedure. Some surgeons use the balloon as a bridge -- helping patients lose enough weight to reduce surgical risk before a joint replacement, cardiac procedure, or even a sleeve.
- Patients who've been denied surgical coverage and aren't candidates for self-pay surgery abroad. The balloon costs less and requires less medical infrastructure, making it more accessible.
- Patients who tried and failed non-invasive approaches but aren't ready for the permanence of surgery.
Poor candidates
- BMI above 45-50. The balloon won't produce enough weight loss to meaningfully change the clinical picture. These patients need a sleeve, bypass, or duodenal switch.
- Patients with active gastric ulcers, large hiatal hernias, or prior gastric surgery. The balloon sits inside the stomach -- existing structural problems make placement risky or impossible.
- Patients unwilling to commit to the dietary programme. The balloon without behavioural change is an expensive way to lose weight temporarily.
What a gastric balloon costs in Colombia
A gastric balloon at an accredited Colombian hospital typically costs $2,500 to $4,500. That includes the endoscopy, sedation, balloon device, placement, observation, and a set number of follow-up visits. The programme-level nutritional support (monthly sessions for 6 months) is usually bundled in Colombia; in the US, it's often billed separately.
The US self-pay price for the same procedure is $6,000 to $9,000. No major US insurance carrier covers the gastric balloon for weight loss -- it's considered investigational by most payers, despite FDA clearance and a substantial evidence base.
The two-procedure trap
Some patients get a balloon, lose 30 pounds, regain it, and then get a sleeve -- paying for both. If you're considering the balloon because you're nervous about surgery, that's reasonable. But if the evidence says you'll likely need surgery anyway (BMI 40+, significant metabolic disease), the balloon may add cost and delay without changing the destination. Have this conversation with a surgeon before choosing the balloon, not after.
The balloon in Colombia -- what to expect
The trip is shorter
Because the balloon is an outpatient endoscopic procedure, the in-country stay is shorter than for surgical options. Most patients spend 5-7 days in Colombia rather than the 12-14 days recommended for a sleeve or bypass. That reduces accommodation and companion costs meaningfully.
Follow-up matters more, not less
The balloon's effectiveness depends almost entirely on the dietary programme that accompanies it. Before choosing a Colombian provider, confirm that the programme includes structured nutritional follow-up -- ideally monthly for the full balloon period -- and that this can be done via telehealth after you return home. A programme that places the balloon and sends you home without a follow-up plan is offering a device, not a treatment.
Removal logistics
The balloon must be removed on schedule. If you had it placed in Colombia, you have two options for removal: return to Colombia (another short trip and a second round of travel costs), or have it removed by a gastroenterologist at home. Most US gastroenterologists can remove a standard intragastric balloon -- it's a routine endoscopic procedure. Confirm this arrangement before placement, not after.
Balloon types available in Colombia
| Balloon type | Duration | Placement | Key characteristic |
|---|---|---|---|
| Orbera | 6 months | Endoscopic | Most widely studied, FDA-cleared. The benchmark device. |
| Spatz3 | Up to 12 months | Endoscopic | Adjustable volume. Can be tightened during the treatment period. |
| Elipse / Allurion | ~4 months | Swallowable capsule | No endoscopy for placement or removal -- the balloon deflates and passes naturally. |
The Orbera is the most established device with the longest track record. The Spatz3 offers the advantage of adjustability -- if you plateau, the balloon can be filled with more saline. The Allurion capsule eliminates the need for endoscopy entirely, which is appealing but means the physician has less control over placement and no ability to inspect the stomach during the procedure.
The honest assessment
The gastric balloon is a legitimate bariatric tool. It produces meaningful weight loss in the right patients, it carries lower procedural risk than surgery, and it costs less. For patients with a BMI of 30-40 who aren't ready for or don't qualify for surgery, it's a reasonable option.
It's also the option most likely to disappoint if expectations aren't calibrated. The weight loss is modest compared to surgery, the rebound risk is real, and the balloon is temporary by design. It works best as part of a comprehensive programme with dietary support, behavioural change, and a clear plan for what happens after removal.
The balloon creates space -- in your stomach and in your calendar -- to build new habits. What you build in that space determines whether the weight stays off.
