What Is a Gastric Balloon and How Does It Work

A gastric balloon is a medical device placed inside your stomach to help with weight loss. The procedure involves inserting a deflated balloon through your mouth and down your esophagus into your stomach. Once in place, the doctor fills the balloon with saline solution (salt water) or sometimes a special gas. The balloon takes up space in your stomach, which makes you feel full sooner when eating. This feeling of fullness with smaller meal portions is the main mechanism that helps people reduce calorie intake.

The balloon itself is typically made of silicone or similar medical-grade materials that can withstand stomach acid. It remains in your stomach for a set period, usually between 6 months and 1 year, depending on the type. During this time, your body adjusts to eating smaller amounts of food. The goal is not just temporary weight loss, but learning new eating habits that can continue after the balloon is removed.

Different types of gastric balloons exist. Some are filled with liquid, others with gas. Some balloons are designed to dissolve on their own after a certain time period. The Orbera balloon, one of the most well-known types, typically stays in place for 6 months. The Reshape balloon can remain for up to 1 year. Newer options like the Obalon balloon use gas and can be placed in multiples. Each type has different insertion methods, duration, and how they function.

The placement procedure itself usually takes 20 to 30 minutes. You receive sedation to keep you comfortable during the process. There is no surgery involved—no cuts are made in your body. Most people go home the same day, though someone else must drive them due to the sedation medication. Within a few days, most people resume normal activities, though they typically follow dietary guidelines during recovery.

Practical takeaway: Understanding how gastric balloons work helps you know whether this approach might align with your weight loss goals. A gastric balloon creates physical fullness rather than surgically altering your digestive system, and it is a temporary intervention meant to help establish better eating patterns.

Types of Gastric Balloons Currently Available

Several gastric balloon options exist, each with different characteristics. The Orbera intragastric balloon has been available since the 1980s and was the first balloon approved by the U.S. Food and Drug Administration (FDA). It is a single silicone balloon filled with saline solution. The Orbera remains in the stomach for 6 months. During this time, patients typically see weight loss, with studies showing an average loss of 30 pounds or more, though individual results vary significantly based on diet and lifestyle changes.

The Reshape Duo balloon (formerly called ReShape) is another FDA-approved option. This system uses two balloons instead of one, which some doctors believe provides better weight distribution and reduces the risk of balloon deflation. The Reshape system can stay in place for up to 1 year, which is longer than the standard Orbera timeframe. Because it remains longer, some people may experience more sustained weight loss, though this also requires longer commitment to dietary changes.

The Obalon gastric balloon system works differently from the other options. Rather than being inserted deflated and then filled, Obalon balloons are swallowed as capsules. After the capsule reaches your stomach, a thin tube guides gas into the capsule to inflate it. Obalon allows for placement of multiple balloons—up to three—over several weeks. Each balloon is filled with nitrogen gas. The system stays in place for 6 months total. Some people find this method easier since it does not require sedation for placement, though placement still requires a doctor's office visit and imaging guidance.

The Spatz3 balloon is a newer option designed with adjustability in mind. After placement, the balloon can be deflated or inflated further depending on how the patient is tolerating it and their weight loss progress. This adjustability feature allows doctors to customize the treatment more precisely to individual needs. The Spatz3 can remain in place for up to 1 year.

Newer balloons in development or available in other countries include the Elipse balloon, which is designed to dissolve and pass naturally through your system after about 4 months, eliminating the need for removal. Understanding these different options helps explain why your doctor might recommend one type over another based on your specific situation.

Practical takeaway: Different balloon types offer varying durations, insertion methods, and features. Learning about these differences can help you understand what to expect if you pursue this treatment option and why your doctor recommends a particular type.

What to Expect During the Insertion Procedure

The gastric balloon insertion process begins with pre-procedure preparation. You will be asked to fast—typically for 6 to 8 hours before the appointment—so your stomach is empty. This empty stomach allows the doctor to see clearly during the procedure and reduces the risk of complications. You may also receive specific instructions about medications to stop taking before the procedure. Some blood thinners or certain diabetes medications need to be paused temporarily.

When you arrive at the medical facility, staff will place an IV line in your arm. Through this IV, you will receive sedation medication that keeps you comfortable and relaxed during the procedure but does not put you completely to sleep. You remain breathing on your own. The sedation helps you not feel pain or remember much of the procedure afterward. A medical team monitors your heart rate, blood pressure, and oxygen levels throughout.

The actual insertion involves the doctor passing a thin tube called an endoscope through your mouth, down your esophagus, and into your stomach. The endoscope has a camera that allows the doctor to see inside your stomach. For most balloon types, a deflated balloon is attached to or passed through this endoscope. Once the balloon reaches your stomach, the endoscope is carefully positioned, and the balloon is filled with saline or gas through a small tube. Once properly filled and positioned, the doctor removes the endoscope, leaving the balloon behind in your stomach.

The entire procedure typically lasts 20 to 30 minutes. After completion, you move to a recovery area where medical staff monitor you as the sedation wears off. This recovery period usually takes 1 to 2 hours. You will not be able to drive or operate machinery for 24 hours after sedation, so you must arrange transportation in advance. Most people experience minimal discomfort during the procedure itself due to the sedation, though some report mild throat soreness afterward.

After leaving the facility, you will have specific instructions about eating and drinking. Typically, you begin with clear liquids and gradually progress to soft foods over several days. Your doctor will provide a detailed post-insertion diet plan. Most people return to work or regular activities within a few days, though you follow dietary restrictions for a longer period.

Practical takeaway: Knowing the step-by-step process helps reduce anxiety about the procedure. The insertion is quick, non-surgical, and performed by a trained doctor using imaging guidance to ensure proper placement.

Dietary Changes and Lifestyle Adjustments During Balloon Treatment

The gastric balloon works best when combined with intentional dietary changes. Simply having the balloon is not enough to produce lasting weight loss—behavioral and eating habit changes are equally important. Immediately after insertion, your diet progresses through stages. For the first few days, you consume only clear liquids like broth, water, and tea. This allows your stomach to adjust to the balloon's presence.

After several days, you progress to pureed foods and soft foods. These might include yogurt, mashed potatoes, soups without chunks, scrambled eggs, and soft vegetables. This stage typically lasts 1 to 2 weeks. Following this, you gradually return to regular foods, but in much smaller portions. The balloon's presence means you feel satisfied with smaller amounts. Many people find they can eat only half to one-third of the portion sizes they previously consumed.

Throughout balloon treatment, certain foods should be avoided or limited. These include carbonated beverages, which can cause gas and discomfort. Fizzy drinks may also put pressure on the balloon. High-calorie, high-sugar foods should be limited because they provide many calories without much nutritional value, and your smaller stomach capacity means every bite counts. Tough or difficult-to-digest foods like tough meats or high-fiber vegetables that require extensive chewing can sometimes cause discomfort with the balloon in place.

Eating habits matter significantly.
