Gastric balloon guide
A gastric balloon is a non-surgical weight loss procedure designed for individuals struggling with obesity who haven't found success with diet and exercise alone. This temporary medical device is placed in the stomach and partially filled with saline solution, reducing the available space in the stomach and helping patients feel fuller faster. Unlike surgical weight loss procedures such as gastric bypass or sleeve gastrectomy, the gastric balloon is reversible and typically remains in place for 6-12 months, depending on the specific type used. It serves as a tool to help patients develop healthier eating habits while providing the physical restriction that can make portion control easier.
What is a Gastric Balloon?
A gastric balloon is a soft, expandable medical device made of silicone that is temporarily placed in the stomach to aid weight loss. The procedure begins with the deflated balloon being inserted through the mouth and down the esophagus using an endoscope (a thin, flexible tube with a camera). Once positioned correctly in the stomach, the balloon is filled with a sterile saline solution, sometimes mixed with a small amount of methylene blue dye. This dye serves as a safety feature—should the balloon leak, the patient’s urine will turn blue, alerting them to seek medical attention immediately.
There are several types of gastric balloons available today, including single balloons, dual balloons, and adjustable balloons. The most common varieties in clinical use include the Orbera balloon (single balloon system), the ReShape Duo (dual balloon system), and the Spatz3 (adjustable balloon), each with slightly different designs and placement durations. Most balloons remain in place for 6 months, though some newer models can stay for up to 12 months.
How Does a Gastric Balloon Work?
The gastric balloon works through several mechanisms that collectively contribute to weight loss. First and foremost, the balloon occupies space in the stomach, reducing its capacity and helping patients feel satisfied with smaller portions. When the stomach contains less food, patients experience earlier satiety, which helps reduce overall caloric intake. Additionally, the presence of the balloon slows gastric emptying (the rate at which food leaves the stomach), prolonging the feeling of fullness after meals.
Beyond these physical effects, the balloon serves as a behavioral training tool. During the months the balloon is in place, patients work with dietitians and healthcare providers to establish healthier eating habits and lifestyle changes. This comprehensive approach combines the physical restriction of the balloon with behavioral modification, aiming to create sustainable weight loss that continues even after the balloon is removed. Most patients undergo regular follow-up appointments to monitor progress, discuss challenges, and make adjustments to their diet and exercise routines.
Is Gastric Balloon Safe?
The gastric balloon procedure has demonstrated a favorable safety profile compared to invasive bariatric surgeries. As a non-surgical intervention, it avoids the risks associated with general anesthesia and surgical complications such as infections and incision healing problems. However, like any medical procedure, gastric balloons are not without risks.
Common side effects include nausea, vomiting, and abdominal discomfort, particularly in the first few days after placement. These symptoms typically resolve within a week as the body adjusts to the presence of the balloon. More serious but rare complications can include balloon deflation, intestinal obstruction, gastric perforation, and esophageal or gastric ulceration. The risk of serious adverse events is generally considered low, with studies reporting severe complication rates of less than 2%.
Patient selection plays a crucial role in safety outcomes. Gastric balloons are typically recommended for patients with a Body Mass Index (BMI) between 30 and 40, who have been unable to achieve weight loss through diet and exercise alone, and who do not have certain gastrointestinal conditions such as hiatal hernia, ulcers, or previous gastric surgery. Proper screening and adherence to these criteria help minimize risks.
Gastric Balloon Types and Options
Several gastric balloon systems are available, each with distinct features that may benefit different patients. The table below compares some of the widely used gastric balloon systems:
| Balloon System | Placement Duration | Fill Volume | Special Features | Average Weight Loss Potential |
|---|---|---|---|---|
| Orbera | 6 months | 400-700 ml | Single balloon system, extensive clinical data | 10-15% of total body weight |
| ReShape Duo | 6 months | 750-900 ml (two balloons) | Dual balloon design for added safety | 7-10% of total body weight |
| Spatz3 | Up to 12 months | 400-700 ml (adjustable) | Can be adjusted during placement period | 15-20% of total body weight |
| Obalon | 6 months | 250 ml per balloon (up to 3) | Swallowed as a pill, no endoscopy for placement | 7-10% of total body weight |
| Elipse | 4 months | 550 ml | Self-deflating, passes naturally without removal procedure | 10-15% of total body weight |

Effectiveness and Expected Results
The effectiveness of gastric balloons varies among patients, but research indicates average weight loss of 10-15% of total body weight during the treatment period. A systematic review of clinical studies showed that patients typically lose between 10-45 pounds (4.5-20 kg) while the balloon is in place. Several factors influence success rates, including patient adherence to dietary guidelines, participation in supervised exercise programs, and regular follow-up with healthcare providers.
Long-term success depends largely on the patient’s ability to maintain the lifestyle changes adopted during treatment. Studies tracking patients after balloon removal show varied results, with some maintaining weight loss and others regaining weight over time. The most successful patients are those who use the balloon period as an opportunity to fundamentally change their relationship with food and establish sustainable exercise habits.
Recovery and Lifestyle Changes
Recovery from gastric balloon placement is relatively quick compared to surgical weight loss procedures. Most patients experience nausea, stomach discomfort, and possibly vomiting during the first 3-5 days after insertion. These symptoms are typically managed with prescribed medications and gradually subside as the body adapts to the balloon.
The effectiveness of the gastric balloon depends heavily on accompanying lifestyle changes. Patients are typically placed on a structured diet plan that progresses from liquids to pureed foods and finally to small, nutrient-dense meals. Regular physical activity is encouraged, starting with light exercise and gradually increasing intensity. Behavioral therapy and support groups can also play important roles in addressing emotional eating patterns and providing ongoing motivation.
