Understanding Gastric Balloon Procedures: What They Are and How They Work
A gastric balloon procedure is a non-surgical weight loss treatment that involves placing a soft, expandable balloon inside the stomach. The balloon takes up space in the stomach, which helps people feel fuller faster and eat smaller portions during meals. Unlike gastric bypass or gastric sleeve surgery, this procedure does not involve cutting or permanently altering the digestive system.

The balloon itself is typically made from silicone and is roughly the size of a grapefruit when inflated. During the placement procedure, a doctor guides the deflated balloon down the throat using an endoscope—a thin tube with a camera attached. Once the balloon reaches the stomach, it is filled with a sterile saline solution (saltwater) or sometimes a special gas. The entire placement process usually takes about 20 to 30 minutes and is performed under sedation in an outpatient setting.
According to medical studies, patients with gastric balloons typically lose between 20 to 50 pounds over the six-month period while the balloon is in place. Weight loss results depend on individual factors including starting weight, diet changes, physical activity levels, and overall commitment to lifestyle modifications. The balloon remains in the stomach for approximately six months, after which it is removed in another brief endoscopic procedure.
The procedure works differently than other weight loss options. With gastric bypass surgery, food is rerouted around part of the small intestine, permanently reducing calorie absorption. With gastric sleeve surgery, a portion of the stomach is surgically removed. The gastric balloon, by contrast, works primarily by promoting feeling of fullness and satiety, which naturally leads to consuming fewer calories. This mechanical approach, combined with dietary changes and lifestyle modifications, creates the conditions for weight loss.
Several types of gastric balloons are available, though not all may be offered in Lewisville. The Orbera balloon has been FDA-approved since 2015 and is one of the most commonly used options. Other balloons include the Reshape Duo, which features two chambers for added stability, and the Spatz3, which can be adjusted in size during the treatment period if needed. Each balloon type has slightly different characteristics, but all operate on the same basic principle of occupying stomach space.
Practical takeaway: Understanding the basic mechanics of how a gastric balloon works helps people determine whether this approach aligns with their weight loss goals and preferences compared to surgical alternatives.
The Gastric Balloon Procedure: What to Expect Before, During, and After
Before undergoing a gastric balloon placement, patients typically meet with their medical team for a consultation and evaluation. During this appointment, doctors review medical history, current medications, and any conditions that might affect the procedure. Patients may receive blood tests and imaging studies to ensure they are medically stable. The consultation also includes discussion of realistic expectations, potential side effects, and the importance of dietary and lifestyle changes during the six-month balloon period.

Pre-procedure instructions usually include fasting for 6 to 8 hours before the appointment, typically starting the night before. Patients are asked to avoid solid foods and sometimes clear liquids as well. Certain medications may need to be adjusted or held before the procedure. The medical team will provide detailed written instructions specific to each patient's situation. It is important to follow these instructions carefully, as they help ensure the procedure goes smoothly and safely.
During the procedure itself, patients receive sedation to help them relax and remain comfortable. The doctor passes a thin endoscope through the mouth and down the esophagus into the stomach. This allows the doctor to see inside the stomach and position the deflated balloon correctly. Once positioned, the balloon is filled with saline or gas through a small tube, then the endoscope is carefully removed. Most patients remain in the facility for a few hours for monitoring and recovery from sedation before being discharged home.
After balloon placement, the first few days typically involve some discomfort as the body adjusts. Common experiences during the first week include nausea, mild abdominal cramping, and a sense of fullness even after eating small amounts. Some patients report headaches or dizziness. These symptoms usually decrease significantly within 3 to 7 days as the stomach adapts to the balloon's presence. Doctors often prescribe anti-nausea medication to help manage symptoms during this adjustment period.
Dietary changes begin immediately after placement. For the first few days, patients are restricted to clear liquids. Over the next week or two, the diet gradually progresses to pureed foods, then soft foods, and eventually to regular foods eaten in much smaller portions. Physical activity can usually resume gradually after a few days, starting with light walking and progressing as tolerated. Most patients can return to normal activities, including work, within a few days to a week.
Practical takeaway: Knowing what to expect at each stage of the gastric balloon journey helps patients prepare mentally and physically, manage early discomfort, and make informed decisions about timing and commitment to the procedure.
Medical Considerations and Safety Information for Gastric Balloon Treatment
Gastric balloon procedures are generally considered safe when performed by experienced medical professionals. The FDA has reviewed and cleared certain gastric balloon devices for use in the United States. However, like all medical procedures, gastric balloons do carry some risks and potential complications that patients should understand before proceeding.

The most common side effects during the first weeks are temporary and manageable. Nausea affects most patients to some degree, though it typically resolves as the body adjusts. Some patients experience vomiting, particularly early in the adjustment period. Abdominal pain or cramping occurs in many patients and is usually mild to moderate. Constipation and changes in bowel habits are common due to dietary changes and reduced food intake. Headaches, fatigue, and dizziness can occur, particularly related to the sedation and dietary changes during early recovery.
Serious complications are uncommon but possible. Gastric perforation, where the balloon creates a hole in the stomach wall, is a rare but serious complication requiring emergency surgery. Rates of this complication are typically reported between 0.5 and 1 percent. Balloon deflation can occur, meaning the balloon loses its contents and becomes ineffective; some balloons naturally deflate over time as part of their design. Upper gastrointestinal obstruction, where the balloon partially blocks the digestive tract, is another rare complication. Pancreatitis, inflammation of the pancreas, has been reported in very rare cases.
Certain medical conditions make gastric balloon treatment inappropriate. Patients with a history of significant gastrointestinal surgery, severe inflammation of the stomach lining, active ulcers, or bleeding disorders may not be candidates. Pregnancy is an absolute contraindication, as is the inability to commit to dietary changes. Patients taking aspirin or blood-thinning medications may need adjustment of these medications. Those with severe psychological conditions affecting eating behaviors should be carefully evaluated before proceeding.
Ongoing medical monitoring during the balloon period is essential. Patients typically attend follow-up appointments at 2 weeks, 1 month, 3 months, and 6 months after placement. These appointments include assessment of weight loss progress, review of dietary compliance, discussion of any symptoms or concerns, and reinforcement of healthy lifestyle habits. Some patients may need additional support from nutritionists or behavioral health professionals to maximize results.
Practical takeaway: Understanding both the common temporary side effects and rare serious complications allows patients to make informed decisions and recognize warning signs that require immediate medical attention.
Nutritional Changes and Dietary Guidelines During Gastric Balloon Treatment
Dietary modification is one of the most critical components of successful gastric balloon treatment. The balloon itself is a tool that promotes fullness, but lasting weight loss depends on patients making conscious choices about what and how much they eat. Many patients work with registered dietitian nutritionists who provide personalized guidance throughout the six-month balloon period.

The immediate post-placement diet follows a specific progression. Days 1 through 3 typically involve only clear liquids such as broth, clear juice without pulp, water, and non-carbonated beverages. Days 4 through 7 progress to full liquids including protein shakes, yogurt, and cream-based soups. Days 8 through 14 introduce pureed foods such as mashed potatoes, soft scrambled eggs, and blended vegetables. After two weeks, patients transition to soft, regular foods eaten in small portions. Throughout this progression, portion sizes remain tiny—often just 1 to 2 ounces per
