The gastric balloon is a temporary, minimally invasive device placed in the stomach to help people lose weight by promoting an earlier feeling of fullness. Filled with saline or air, the soft balloon reduces available stomach volume so patients can eat smaller portions and consume fewer calories. It is generally left in place for about six months, during which time patients work closely with clinicians to adopt healthier eating patterns, exercise routines, and behavioral strategies that aim to preserve weight loss after removal.

Who is a suitable candidate?

Gastric balloons are typically recommended for adults whose Body Mass Index (BMI) is between 30 and 40 and who have struggled to achieve sustainable weight loss through diet and exercise alone. Ideal candidates commonly meet several of the following criteria:

• Willingness to commit to long-term lifestyle changes involving diet, activity, and follow-up care
• No history of major stomach or esophageal surgery
• Absence of certain gastrointestinal disorders, such as active ulcers or inflammatory bowel disease
• Not pregnant and not planning pregnancy within the next year
• Prepared to participate in a medically supervised weight loss program that includes nutritional guidance and monitoring

It’s important to understand that the balloon is an adjunctive tool, not a permanent fix. Its purpose is to jump-start weight loss and support patients while they learn healthier habits.

How the gastric balloon helps you lose weight

Once positioned in the stomach and inflated, the balloon occupies space that would otherwise hold food. This mechanical effect reduces hunger sensations and helps people feel satisfied after smaller meals. The resulting decrease in calorie intake, combined with lifestyle modifications guided by healthcare providers, typically produces steady weight loss during the device’s placement.

Clinical data indicate that many patients can expect notable reductions in body weight—on average around 10–15% of total body weight—over the six-month treatment window. Beyond the scale, losing this amount of weight often improves metabolic markers and reduces risks tied to obesity.

Benefits of choosing a gastric balloon

• Non-surgical: The procedure avoids incisions and permanent changes to the digestive tract associated with bariatric surgeries.
• Reversible: The balloon can be removed, returning the stomach to its baseline anatomy.
• Quick recovery: Most patients resume normal activities within days after placement.
• Meaningful weight loss: Average reductions of 10–15% of body weight within six months are commonly reported.
• Health improvements: Weight loss may translate into better blood pressure control, improved blood sugar management, and relief from obstructive sleep apnea among other obesity-related conditions.
• Psychological boost: Early, visible progress can increase motivation and self-confidence, helping patients stay engaged in lifestyle changes.

Potential risks and side effects

While many people tolerate the gastric balloon well, there are risks and side effects to consider. Common early symptoms include nausea and vomiting as the body adapts to the device; these typically lessen after the first few days to weeks. Other possible issues include:

• Abdominal pain, cramping, or persistent discomfort
• Balloon deflation, which in rare instances may lead to passage through the digestive tract or obstruction
• Irritation of the stomach lining that could contribute to gastric ulcers
• Dehydration resulting from prolonged vomiting or reduced fluid intake
• Increased acid reflux or heartburn

Any severe, persistent, or unusual symptoms should be reported to a healthcare provider immediately. Careful pre-procedure screening and close follow-up help reduce risks.

Cost considerations

Costs vary widely depending on location, the type of balloon used, and whether the program includes comprehensive support services. Below is a general cost overview.

---

Provider Type	Estimated Cost Range	What’s Included
Private Clinics	$6,000 - $9,000	Balloon placement, removal, follow-up care
Hospital-Based Programs	$7,500 - $12,000	Procedure, comprehensive weight loss program
Medical Tourism Options	$4,000 - $7,000	Procedure, some follow-up care (travel costs extra)

Prices are estimates and may change over time. Check with providers for current rates and specific inclusions. Many insurers consider the gastric balloon elective and may not cover the procedure, so patients should verify benefits and explore financing if needed.

Preparing for the procedure and life after the balloon

Before placement, patients usually undergo a medical evaluation to confirm suitability and to rule out contraindications. Education on diet, hydration, and what to expect after placement helps improve comfort and outcomes. During the six months with the balloon in place, regular follow-up appointments support nutritional counseling, physical activity plans, and behavioral counseling.

After removal, the goal is to maintain the momentum gained while the balloon was in place. Long-term success depends on continuing healthy eating habits, consistent exercise, and regular medical monitoring when appropriate.

Making an informed choice

The gastric balloon offers a middle ground between conservative lifestyle interventions and more invasive bariatric surgery. It can be a powerful, temporary aid for people who need support to reduce portion sizes and kick-start weight loss. However, it is not suitable for everyone, and careful evaluation by a qualified medical team is essential to determine if it fits an individual’s health profile and goals.
