If you’ve been researching gastric balloon options, you’ve probably come across two names again and again: Orbera and Obalon. Both can help you lose weight without surgery—but they work in very different ways, and their results aren’t identical. At Lap Band LA, Dr. David Davtyan has used both systems with thousands of patients across Los Angeles, and he’s seen firsthand what tends to deliver the strongest, most sustainable outcomes. Here’s a clear, side-by-side look at Orbera vs Obalon results, how they compare in real life, and which might be the better fit for your goals and lifestyle.
Why Compare Orbera and Obalon?
When considering non-surgical weight loss, it’s important to understand the details. Orbera and Obalon are the two most well-known, FDA-approved gastric balloon systems, but the differences between them can have a real impact on your experience and results. A thorough gastric balloon comparison helps you make a choice based on facts, not just marketing.
Both are non-surgical gastric balloons — but they work differently
At their core, both systems work by taking up space in your stomach to help you feel full faster and eat less. However, their design, placement method, and the way they feel inside your body are distinct. Orbera is a single, durable balloon filled with saline, while Obalon is a system of three smaller, lighter balloons filled with gas. These Orbera Obalon differences are key to understanding the comparison.
Why understanding results, comfort, and safety helps you choose wisely
Choosing the right tool is about balancing expected weight loss with comfort and safety. Some patients prioritize the most powerful tool for results, while others may prefer a gentler adjustment period. By comparing the clinical data, common side effects, and placement process for both, you can align your choice with your personal health goals and tolerance for initial discomfort.
What we see most often among our Los Angeles patients
In our practice, we find that Los Angeles patients value effectiveness and a clear, structured program. While both balloons are effective tools, the conversation often comes down to the desired level of intervention and the type of support needed to achieve and maintain results. We’ll walk you through what the real-world Orbera vs Obalon experience looks like for people with busy LA lifestyles.
Takeaway: Comparing Orbera and Obalon is about matching the right tool—based on results, comfort, and procedure—to your specific body and goals.
Orbera vs. Obalon — A Quick Overview
Before diving into the results, it’s helpful to understand the fundamental differences in how each system is designed and used.
Orbera: the single fluid-filled balloon
The Orbera gastric balloon is a single, soft, but durable silicone balloon. It is placed in the stomach endoscopically while you are under light sedation. Once in place, it is filled with a sterile saline solution about the size of a grapefruit. It remains in place for six months.
Obalon: the swallowable gas-filled balloon system
The Obalon system is unique because it involves three separate, smaller balloons that are filled with gas. The first balloon is placed via a swallowable capsule attached to a tiny catheter—no sedation is required for placement. Two additional balloons are swallowed and inflated in the following weeks, creating a gradual increase in volume.
Key differences in placement, number of balloons, and removal
The Orbera vs Obalon procedure differences are significant. Orbera involves one balloon placed and removed via endoscopy under sedation. Obalon involves three balloons placed without sedation (you swallow a capsule) but requires an endoscopic procedure under sedation for removal. The single, heavier fluid-filled Orbera balloon often provides a stronger feeling of fullness compared to the three lighter, gas-filled Obalon balloons.
Takeaway: Orbera is a single, fluid-filled balloon placed once via endoscopy, while Obalon is a three-balloon, gas-filled system placed gradually by swallowing a capsule.
How Each Gastric Balloon Works
While both systems occupy space in the stomach, their mechanism of action and treatment timeline differ slightly.
The science behind how balloons create fullness
Both balloons work by physically filling a portion of the stomach, which reduces the amount of food you can eat at one time. This physical presence also stimulates nerve receptors in the stomach wall that send signals of fullness to the brain. This helps you learn portion control and retrain your hunger cues. The weight and volume of the balloon influence how strong this sensation is.
How long they stay in place
The treatment duration for both Orbera and Obalon is six months. This period is designed to be long enough for you to lose a significant amount of weight and, more importantly, to solidify the new dietary and lifestyle habits needed for long-term maintenance after the balloon is removed.
What happens during placement and removal
For Orbera, both placement and removal are quick, 20-minute endoscopic procedures performed under light sedation. For Obalon, the placements are even quicker, in-office procedures where you swallow a pill-sized capsule. However, the removal of all three Obalon balloons is done at the six-month mark through a single endoscopic procedure, similar to the Orbera removal.
Takeaway: Both balloons create fullness for six months, but the placement process is the main distinction: Orbera uses endoscopy, while Obalon uses a swallowable capsule.
Orbera vs. Obalon Results — What the Data Shows
When comparing Orbera vs Obalon weight loss, it’s important to look at both the clinical trial data and the real-world outcomes we see in our practice.
Average total body weight loss (TBWL) for each system
In clinical trials, patients with the Orbera balloon lost, on average, about 10-15% of their total body weight. Obalon patients lost an average of around 6-7% of their total body weight. This difference is significant and is a key factor for many patients when making a decision.
Clinical trial outcomes vs. real-world patient results
While clinical trials provide a benchmark, real-world results can vary. At our Los Angeles clinics, we consistently see patients achieve results at the higher end of these ranges, and sometimes beyond, with a comprehensive support program. However, the trend remains the same: Orbera generally produces a higher average weight loss than Obalon. This is likely due to the single balloon’s larger volume and weight, which creates a more powerful sense of satiety.
Why lifestyle support impacts success more than balloon type
The balloon is just a tool. The most critical factor in your success is your commitment to the accompanying nutrition and lifestyle program. A patient with an Obalon who is highly engaged with their dietitian may have better results than a less-engaged patient with an Orbera. That’s why we build a robust, six-month coaching program around every balloon placement.
Takeaway: Clinical data and our real-world experience show that Orbera typically leads to significantly more weight loss than Obalon, but patient commitment to the lifestyle program is the ultimate driver of success.
Before-and-After Results — What to Expect in 6 Months
Looking at the journey month by month helps paint a clearer picture of the gastric balloon experience.
Typical weight loss milestones month by month
With both systems, the most rapid weight loss occurs in the first three months. This is when the balloon’s restrictive effect is most novel and your motivation is high. After month three, weight loss tends to slow down to a steadier pace. This is a normal and expected part of the process, as the focus shifts from rapid loss to habit formation for long-term maintenance.
Visual differences: volume, appetite, and energy levels
Orbera before and after stories often highlight a dramatic reduction in appetite from day one due to the balloon’s substantial presence. Obalon patients report a more gradual decrease in appetite as each of the three balloons is added. With successful weight loss from either system, patients universally report a significant increase in energy levels, improved mobility, and a noticeable change in how their clothes fit.
What our Los Angeles patients report most often after 6 months
After six months, patients from across Los Angeles tell us the biggest change isn’t just their reflection in the mirror. It’s the newfound confidence and freedom they feel. They talk about having the energy to hike in the Santa Monica mountains, feeling comfortable at beach gatherings, and no longer feeling like their weight is holding them back from enjoying the active LA lifestyle.
Takeaway: The most significant Orbera vs Obalon before and after difference is the initial appetite suppression, but both paths can lead to life-changing improvements in energy and confidence over six months.
Comfort and Tolerance — Which Feels Easier to Live With?
The adjustment period is a key part of the Orbera vs Obalon comparison. How your body adapts in the first week can set the tone for your journey.
How your body adjusts in the first week
The first 48-72 hours after placement are the most challenging for both systems. The body is adjusting to a foreign object, which commonly triggers nausea, cramping, and abdominal discomfort. However, these symptoms are generally more pronounced with the Orbera balloon due to its larger size and fluid-filled weight.
Common side effects (and how we minimize them)
Nausea, vomiting, and cramping are the most common Orbera side effects, and they are also seen with Obalon, though often to a lesser degree. At Lap Band LA, we manage this proactively with a take-home medication kit and close follow-up. While the Obalon adjustment may be milder for some, the Orbera symptoms are temporary and typically resolve within a few days.
What to expect day to day
After the initial adjustment, most patients adapt well to either balloon. The feeling of fullness becomes the new normal. Some patients with Orbera are more consistently aware of the balloon’s presence, which they find helpful for portion control. Obalon patients may feel the restriction is less intense, which can be more comfortable but may also be less effective at curbing appetite.
Takeaway: Obalon generally offers a gentler initial adjustment period, but Orbera’s more intense side effects are temporary and often correspond with more powerful appetite suppression.
Safety and FDA-Approved Studies
Both Orbera and Obalon have undergone rigorous testing to receive FDA approval, and both are considered safe when placed by an experienced physician.
What clinical trials show about complication rates
Clinical trials for both devices have demonstrated a strong safety profile. The most serious risks, such as balloon deflation or intestinal obstruction, are very rare. The most common issues are the initial intolerance symptoms (nausea and vomiting), which can sometimes lead to a patient requesting early removal, though this is uncommon.
Safety records and long-term outcomes
Both balloons have been used in hundreds of thousands of patients worldwide with solid safety records. The Orbera FDA approval and the Obalon FDA approval are based on data showing that the benefits of the weight loss achieved far outweigh the risks for appropriate candidates.
Our patient screening and follow-up process at Lap Band LA
The key to gastric balloon safety is a thorough screening process and diligent follow-up care. At Lap Band LA, we conduct a comprehensive medical evaluation to ensure you are a candidate. Our close monitoring during the first week and regular check-ins throughout the six months allow us to manage side effects and address any potential issues early.
Takeaway: Both balloons have strong, FDA-supported safety profiles; the most critical safety factor is choosing an experienced doctor who provides thorough screening and follow-up.
Cost and Value — Which Is More Affordable Long-Term?
Gastric balloon procedures are typically self-pay, so understanding the cost and what it includes is essential.
Why Orbera and Obalon costs vary
The cost can vary based on geographic location and what is included in the program. The Obalon system, involving three separate balloon placements and the manufacturing of three devices, can sometimes be priced differently than the single-balloon Orbera procedure. However, the final price often reflects the comprehensive nature of the program.
What’s included in Lap Band LA’s transparent pricing
When considering the gastric balloon cost in Los Angeles, it’s important to look at the total package. Our all-inclusive pricing at Lap Band LA covers the initial consultation, the device itself, the placement and removal procedures with anesthesia, and the full six-month aftercare program. This includes regular appointments with our dietitian and medical team, ensuring you have the support you need to maximize your results.
Cost vs. durability of results
The true value of a procedure is not just its price, but the durability of its results. Given that Orbera tends to produce more significant weight loss, many patients see it as providing a greater return on their investment. The goal is to lose the weight and keep it off, and a stronger head start can be invaluable for long-term success.
Takeaway: While the Orbera vs Obalon cost can be comparable, the value should be measured by the potential for greater weight loss and the comprehensiveness of the support program included in the price.
Who’s the Best Candidate for Each Balloon?
The ideal candidate for a gastric balloon generally has a Body Mass Index (BMI) between 30 and 40. However, certain nuances might make one balloon a better fit than the other.
BMI and lifestyle factors that affect eligibility
Both balloons are FDA-approved for adults with a BMI in the 30-40 range who have been unable to lose weight through diet and exercise alone. The best candidates are those who are ready to commit to the six-month program and make lasting lifestyle changes.
When Orbera works better (and why)
Orbera is often the preferred choice for patients who want the most powerful non-surgical tool available. If your primary goal is to achieve the maximum possible weight loss and you feel prepared to manage a few days of more intense side effects, Orbera is likely the better option. Its single, larger volume provides a more profound and consistent feeling of fullness.
When Obalon might be a better fit
Obalon might be considered for patients who are extremely anxious about the endoscopic placement or who are very sensitive and concerned about the initial side effects. The swallowable placement and more gradual inflation can feel less intimidating. However, this comes with the trade-off of typically less significant weight loss.
Takeaway: Orbera is generally better for those prioritizing maximum results, while Obalon may appeal to those who prioritize a milder initial experience and non-endoscopic placement.
Real Patient Stories — What We Hear Most Often
While anonymized, the themes we hear from patients offer real-world insight into the Orbera vs Obalon experience.
“I chose Orbera for the simplicity and results.”
Patients who choose Orbera often tell us they were drawn to the “one-and-done” placement. They liked the idea of a single, robust device and were motivated by the superior weight loss results shown in studies. They felt that enduring a few tough days upfront was a worthwhile trade-off for a more powerful tool.
“I picked Obalon because I wanted something lighter.”
Patients who opted for Obalon frequently mention that the idea of swallowing a capsule was less daunting than an endoscopy. They were attracted by the promise of a gentler adjustment period and felt the lighter, gas-filled balloons would be more comfortable to live with day-to-day.
What both groups say about motivation and follow-up support
Regardless of the balloon they choose, successful patients consistently say the same thing: the support program was the key. They credit their regular meetings with our dietitian and the accountability of our follow-up appointments as the factors that truly taught them how to eat and maintain their progress.
Takeaway: Patient reasoning often boils down to a choice between Orbera’s power and Obalon’s gentler approach, but both groups agree that the support program is what drives lasting success.
Long-Term Results — What Happens After the Balloon Comes Out
The six-month balloon period is the training phase. True success is measured by your ability to maintain your new, healthy weight for years to come.
How to maintain your new weight
After the balloon is removed, you must consciously apply the skills you’ve learned. This means continuing to practice portion control, making mindful food choices, staying physically active, and managing emotional eating triggers. The balloon is gone, but the habits must remain.
Follow-up care and coaching programs that make the difference
This is where a high-quality aftercare program becomes so important. We offer long-term follow-up and coaching to provide the accountability and support needed to navigate life after the balloon. Whether it’s a small tweak to your diet or a strategy for an upcoming vacation, we’re here to help.
Why we focus on maintenance at Lap Band LA

Takeaway: Long-term success depends entirely on continuing the healthy habits learned during the 6-month program, ideally with the support of a dedicated maintenance plan.
The Bottom Line — Orbera vs. Obalon in 2025
So, which balloon gives the best outcome? When comparing Orbera vs Obalon in 2025, the evidence and our extensive experience point to a clear conclusion.
A side-by-side summary of results, cost, and comfort
In summary, Orbera typically delivers greater weight loss results. The costs for the complete programs are often comparable, making Orbera a higher value proposition in terms of dollars per pound lost.
