Gastric balloon guide

A gastric balloon is a non-surgical weight loss procedure that involves placing an inflatable silicone device temporarily in the stomach to reduce its capacity, helping patients feel fuller faster and eat less. This minimally invasive approach serves as an alternative for individuals who haven't achieved success with conventional weight loss methods but may not qualify for or desire more extensive bariatric surgeries. The procedure typically takes about 20-30 minutes and is performed endoscopically, with the balloon remaining in place for approximately six months.

What is a Gastric Balloon?

A gastric balloon is a soft, expandable medical device designed to occupy space in the stomach to aid weight loss. Made from silicone material that’s resistant to stomach acid, the balloon is inserted into the stomach while deflated, then filled with a sterile saline solution or gas until it reaches approximately the size of a grapefruit. The filled balloon reduces the available space in the stomach, creating a sensation of fullness that helps patients consume smaller portions and feel satisfied with less food.

There are several types of gastric balloons available, including single balloons, dual-balloon systems, and adjustable balloons. Each variant offers slightly different features, placement methods, and duration of treatment. Most balloons remain in place for six months, though some newer options can last up to a year. The temporary nature of this intervention makes it particularly suitable as a kickstart to longer-term lifestyle changes rather than a permanent solution to weight management.

How Does a Gastric Balloon Work?

The gastric balloon works through several mechanisms that collectively support weight loss. Primarily, the balloon creates a mechanical barrier that physically occupies space in the stomach, reducing its capacity for food. This spatial restriction means patients feel full after consuming smaller amounts of food, naturally decreasing their caloric intake without the feeling of deprivation that often accompanies dieting.

Beyond the physical space limitation, the balloon also delays gastric emptying—the process by which food leaves the stomach and enters the small intestine. This slower emptying extends the feeling of fullness between meals, reducing hunger and snacking behaviors. Additionally, the presence of the balloon may influence hormonal signals related to hunger and satiety, though research on this mechanism is still emerging.

The placement procedure is relatively straightforward and doesn’t require surgical incisions. A specialized doctor uses an endoscope (a thin, flexible tube with a camera) to guide the deflated balloon through the mouth, down the esophagus, and into the stomach. Once positioned correctly, the balloon is filled with sterile saline solution or gas through a small catheter. The entire procedure typically takes 20-30 minutes and is performed under mild sedation or anesthesia. Patients usually return home the same day after a brief monitoring period.

Is Gastric Balloon Safe?

Gastric balloon procedures are generally considered safe when performed by qualified healthcare providers on appropriate candidates. As a non-surgical intervention, it carries fewer risks than invasive bariatric surgeries. However, like any medical procedure, it isn’t without potential complications. Common side effects include nausea, vomiting, abdominal pain, and reflux, particularly in the days immediately following placement. These symptoms typically subside within a week as the body adjusts to the balloon’s presence.

More serious but rare complications may include balloon deflation, intestinal obstruction, stomach perforation, or ulceration. Modern balloons contain a harmless dye that changes urine color if the balloon leaks, alerting patients to potential deflation. The risk of complications can be minimized through proper patient selection, experienced providers, and adherence to follow-up care.

The temporary nature of gastric balloons contributes to their safety profile. Since the device is removed after six months (or up to twelve months for certain types), the body isn’t subjected to long-term foreign object exposure. The removal procedure is similar to the placement—an endoscopic process that deflates and extracts the balloon under mild sedation.

Gastric Balloon Effectiveness and Expected Results

Research shows that patients with gastric balloons typically lose between 10% and 15% of their initial body weight during the treatment period. This translates to approximately 20-50 pounds, depending on starting weight. Results vary significantly between individuals based on their commitment to recommended lifestyle changes, initial weight, medical conditions, and metabolism.

The most significant weight loss usually occurs in the first three months after placement when the balloon’s effects on appetite and satiety are strongest and patient motivation is highest. After removal, maintaining weight loss requires continued adherence to dietary changes and regular physical activity. Studies indicate that without sustained lifestyle modifications, patients may regain a portion of the lost weight within 1-2 years after balloon removal.

Gastric Balloon Costs and Provider Options

The cost of gastric balloon procedures varies significantly based on geographic location, the type of balloon used, provider expertise, and included services. Comprehensive treatment packages generally include the pre-placement evaluation, the procedure itself, the balloon removal after 6-12 months, and varying degrees of nutritional and lifestyle support.


Provider/Balloon Type Average Cost Range Duration What’s Typically Included
Orbera Gastric Balloon $6,000-$9,000 6 months Placement, removal, limited follow-up
Obalon Balloon System $8,000-$11,000 6 months Three balloons placed gradually, removal, some support
ReShape Duo $7,000-$9,000 6 months Dual balloon system, placement, removal, basic support
Spatz3 Adjustable Balloon $8,000-$12,000 Up to 12 months Adjustable balloon, longer duration, placement, removal
Allurion Elipse $4,000-$7,000 4 months Swallowable balloon, self-deflating (no removal procedure)

Prices, rates, or cost estimates mentioned in this article are based on the latest available information but may change over time. Independent research is advised before making financial decisions.

Most medical insurance plans do not cover gastric balloon procedures as they’re often classified as elective weight loss treatments. However, some providers offer financing plans that allow patients to spread the cost over 12-24 months, making the treatment more financially accessible. When comparing providers, potential patients should consider not just the upfront cost but also the comprehensiveness of the support program, provider experience, and success rates.

Conclusion

The gastric balloon offers a middle-ground option in weight loss interventions—more intensive than lifestyle modifications alone but less invasive than bariatric surgery. Its temporary nature makes it particularly suitable as a kickstart to healthier habits or for those needing to lose weight before qualifying for other medical procedures. Understanding what the gastric balloon is, how it works, its safety profile, and expected results can help individuals make informed decisions about whether this option aligns with their weight loss goals and health needs.
