Quick Answer: What is an intragastric balloon?
An intragastric balloon is a minimally invasive device placed in the stomach to assist weight loss. A provider inserts it through the mouth with an endoscope, avoiding surgery and general anesthesia. Filling about one-third of the stomach, it creates early fullness and slows digestion. The six-month program typically helps people with a BMI over 30 achieve moderate weight reduction.
Understanding the Intragastric Balloon System
The intragastric balloon represents a significant advancement in minimally invasive bariatric care. Unlike traditional surgical interventions, this method utilizes a temporary medical implant to physically limit the amount of food the stomach can hold. The term "intragastric" refers to the placement of the device directly inside the stomach cavity.
"The intragastric balloon sits inside your stomach, taking up space... making you feel full and restricting how much you can eat." [1]
This treatment is designed as a comprehensive weight loss program that pairs the physical restriction of the balloon with long-term nutritional and lifestyle counseling. It is particularly effective for individuals who have struggled to lose weight through diet and exercise alone, as obesity often causes the stomach to expand, requiring more food to trigger feelings of fullness.
Candidates for Treatment
In the United States, this therapy is approved for adults with a Body Mass Index (BMI) of about 30 to 40 who have not lost weight with diet and exercise. It serves as a middle-ground option for those who do not qualify for or wish to avoid bariatric surgery.
Category | Description |
Primary Candidates | Individuals with a BMI of 30+ who have not succeeded with traditional weight loss methods. |
Bridge Therapy | Patients with severe obesity (Class III) who use the balloon to lose weight before undergoing safer surgical procedures. |
Surgical Alternative | Those who prefer a temporary, nonsurgical intervention with lower associated risks. |
The Placement Procedure
The insertion of an intragastric balloon is a brief outpatient procedure, typically lasting between 20 and 30 minutes. It does not require incisions or general anesthesia, making it a viable option for many patients.
Preparation: Patients follow a clear liquid diet for several days and fast after midnight before the procedure.
Sedation: A mild sedative is administered to help the patient relax, and the throat is numbed to facilitate the passage of the instruments.
Endoscopic Insertion: A healthcare provider guides an endoscope—a flexible tube with a camera—through the mouth and into the stomach.
Inflation: Once correctly positioned, the balloon is filled with sterile saline or gas, depending on the specific model used.
Finalization: The filling catheter is detached, and the balloon's valve seals automatically to prevent leakage.
Benefits and Expected Results
The primary advantage of the intragastric balloon is its ability to facilitate rapid weight loss without permanent alterations to the digestive anatomy. On average, patients lose approximately 10% of their total body weight or 30% of their excess weight during the six-month treatment period.
Weight loss is typically most significant during the first three months. Beyond the scale, losing even 5% to 10% of body weight can lead to the remission or improved management of obesity-related conditions, including Type 2 diabetes, cardiovascular disease, and hypertension.
Risks and Side Effects
While considered low-risk compared to surgery, the intragastric balloon can cause temporary discomfort as the body adjusts to the implant.
Common Side Effects: Nausea, vomiting, and stomach cramps are frequent during the first few days following placement.
Reflux and Ulcers: Some patients may experience increased acid reflux or the development of peptic ulcers.
Balloon Issues: Though rare, the balloon may deflate or leak, which could lead to an intestinal obstruction if the device migrates. The FDA has also reported rare overinflation, acute pancreatitis, stomach perforation and deaths, so get urgent care for severe or ongoing belly pain, repeated vomiting, a swollen belly or trouble breathing.
Contraindications: The procedure is generally not recommended for individuals with a history of gastrointestinal surgery, hiatal hernias, or active peptic ulcer disease.
Recovery and Long-Term Outlook
After the procedure, patients spend a few hours in recovery before being discharged. The stomach requires time to adapt to the balloon, necessitating a staged dietary progression.
Phase | Duration | Recommended Intake |
Immediate Post-Op | Day 1 | Clear liquids only. |
Adjustment Phase | Days 2–14 | Transition from full liquids to pureed and soft foods. |
Maintenance Phase | Months 1–6 | A long-term, nutritionally balanced diet designed by a specialist. |
After six months, the balloon is removed through a second endoscopic procedure. To maintain weight loss long-term, patients must continue the dietary and lifestyle habits established during the treatment period.
Conclusion
The intragastric balloon offers a powerful, temporary tool for individuals seeking to reclaim their health from obesity. By providing a nonsurgical means to control hunger and portion sizes, it bridges the gap between traditional dieting and permanent surgery. If you are ready to commit to a structured weight loss journey, consult with a healthcare professional to determine if this innovative therapy is right for you.

Frequently Asked Questions
1. How long does the intragastric balloon stay in the stomach?
The device is designed to remain in the stomach for exactly six months, during which time it assists with portion control and satiety.
2. Is general anesthesia required for the procedure?
No, the placement is performed using mild sedation and a local anesthetic to numb the throat, allowing patients to remain awake but relaxed.
3. How much weight can I expect to lose?
Most patients lose an average of 10% of their total body weight, though results depend heavily on adherence to the accompanying diet and exercise program.
4. What happens if the balloon leaks or deflates?
If a saline-filled balloon leaks, the patient may notice a change in urine color (if dye was added). A deflated balloon must be removed promptly to prevent intestinal blockage.
5. Can I feel the balloon inside my stomach?
Patients often feel a sense of fullness or heaviness initially, but most become accustomed to the sensation within a week.
6. What can I eat while the balloon is in place?
After an initial transition through liquids and soft foods, you will follow a healthy, solid-food diet focused on protein and nutrients.
7. Is the weight loss permanent?
Weight loss can be permanent if the patient maintains the healthy lifestyle and dietary habits learned during the six months the balloon was present.
8. Are there any restrictions on physical activity?
Most patients can return to normal activities within a few days, though specific exercise recommendations should be discussed with a provider.
9. Can the balloon be placed if I have had previous stomach surgery?
No, a history of gastrointestinal surgery is typically a contraindication for this procedure due to the risk of complications.
10. How is the balloon removed?
The balloon is removed via a second endoscopic procedure where it is punctured, deflated, and withdrawn through the mouth.
