Gastric Balloon
What is a Gastric Balloon?
A gastric balloon, also known as an intragastric balloon, is a soft, silicone balloon that is inserted into the stomach to help with weight loss. The balloon is filled with saline or gas, taking up space in the stomach and making the patient feel fuller with less food. This procedure is designed to be a temporary, non-surgical weight loss option, typically lasting for six months to one year.

How Does the Gastric Balloon Procedure Work?
The gastric balloon procedure is relatively simple and quick. It is typically performed as an outpatient procedure, meaning that the patient can go home the same day. Here’s how the procedure works:
- Consultation and Evaluation: The process begins with a consultation with a weight-loss specialist who will evaluate whether the gastric balloon is the right option based on the patient’s weight, medical history, and overall health. The patient will undergo various tests to ensure they are suitable candidates for the procedure.
Insertion of the Balloon: The balloon is inserted into the stomach through the mouth using an endoscope, a thin, flexible tube with a camera at the end. This is a minimally invasive procedure that is done under mild sedation, so the patient remains comfortable throughout the process. Once the balloon is in place, it is filled with sterile saline or gas until it expands to take up a portion of the stomach.
- Recovery: The procedure itself takes about 20-30 minutes, and patients are usually monitored for a few hours after the insertion before being discharged. Patients can typically return to their normal activities the next day, but may experience mild nausea or discomfort for the first few days as their body adjusts to the balloon.
- Balloon Removal: After six months to a year (depending on the type of balloon), the gastric balloon is removed. This is done through a similar endoscopic procedure, where the balloon is deflated and taken out through the mouth.
Types of Gastric Balloons
There are several types of gastric balloons available, and the most suitable option depends on the patient’s specific needs and the recommendation of their healthcare provider. Some common types of gastric balloons include:
- Saline-Filled Balloons: These are the most common type of gastric balloons. They are filled with sterile saline once they are placed in the stomach. Some saline-filled balloons can be adjusted over time to increase or decrease the volume based on the patient’s progress.
- Gas-Filled Balloons: Instead of saline, these balloons are filled with a special gas, making them lighter and more comfortable for some patients. They are typically smaller and may cause fewer side effects, such as nausea.
- Swallowable Balloons (e.g., Elipse Balloon): These balloons are swallowed in the form of a capsule and then inflated with liquid or gas once inside the stomach. Unlike other gastric balloons, they do not require an endoscopic procedure for insertion or removal and pass naturally through the digestive system after several months.
Who is a Good Candidate for a Gastric Balloon?
The gastric balloon is a suitable option for individuals who are moderately overweight or obese but do not meet the criteria for bariatric surgery. Ideal candidates for the procedure include:
- BMI (Body Mass Index) between 27 and 40: The gastric balloon is typically recommended for individuals with a BMI between 27 and 40 who need to lose 20-50 pounds (9-23 kg).
- Failed Weight-Loss Attempts: Those who have tried but struggled to lose weight through diet and exercise alone may benefit from the additional support provided by the gastric balloon.
- No Previous Stomach Surgery: Patients who have not undergone previous stomach or bariatric surgeries are generally good candidates for the gastric balloon procedure.
- Commitment to Lifestyle Changes: A gastric balloon is most effective when combined with dietary changes, exercise, and a commitment to a healthy lifestyle. Candidates must be willing to work closely with a nutritionist and follow a structured weight-loss program to achieve lasting results.
Benefits of a Gastric Balloon
There are several benefits to choosing the gastric balloon for weight loss, especially for individuals looking for a non-surgical approach:
- Non-Surgical and Minimally Invasive: Unlike bariatric surgery, the gastric balloon procedure does not require any incisions or permanent alterations to the stomach. It is a relatively quick, outpatient procedure with a fast recovery time.
- Effective Weight Loss: Studies have shown that patients with a gastric balloon can lose an average of 10-15% of their total body weight within six months. This weight loss can lead to improvements in health conditions such as type 2 diabetes, hypertension, and sleep apnea.
- Temporary and Reversible: The balloon is removed after six months to a year, making it a temporary solution. This is ideal for patients who want to jump-start their weight loss and establish healthy habits without undergoing permanent surgery.
- Promotes Healthy Eating Habits: Since the balloon fills up space in the stomach, patients feel full faster and are more likely to eat smaller portions. Over time, this helps establish healthier eating habits that can continue even after the balloon is removed.
Risks and Side Effects of a Gastric Balloon
While the gastric balloon is generally considered a safe procedure, like any medical intervention, it comes with potential risks and side effects. Some of the most common side effects include:
- Nausea and Vomiting: Many patients experience nausea and vomiting in the first few days after the balloon is inserted as the body adjusts to its presence. This typically subsides within a week and can be managed with medication.
- Stomach Discomfort: Patients may feel bloating, cramping, or discomfort due to the balloon taking up space in the stomach. These symptoms are usually temporary.
- Acid Reflux: The presence of the balloon may increase the risk of acid reflux or indigestion. Medications can help manage these symptoms.
- Balloon Deflation or Rupture: In rare cases, the balloon may deflate or rupture prematurely. If this happens, the deflated balloon will pass through the digestive system, but additional procedures may be required to remove it.
- Intolerance: Some patients may not tolerate the balloon well and may require early removal.
