Gastric Balloon vs Gastric Sleeve: Which Weight Loss Option Is Right for You?

“Both options serve different purposes and cater to different patient profiles,” says Dr. Harsh Sheth, a highly regarded bariatric surgeon in Mumbai. “The importance is determining the medical condition of the patient, expectation, and willingness to adopt lifestyle modifications prior to suggesting either method.”

With over 10 years of experience in managing obesity and gastrointestinal conditions, Dr. Sheth is recognized for his expertise in non-surgical weight loss and laparoscopic bariatric surgery in Mumbai. With training from Stanford University and a patient-first approach, he combines technical skill with empathy. His expertise makes him a trusted resource for patients comparing gastric balloon vs gastric sleeve options for weight loss.

A gastric balloon is a non-surgical weight loss procedure. A soft silicone balloon is inserted into the stomach via endoscopy and filled with saline to occupy space. It remains in place for around six months, helping patients feel full quicker and eat less. It’s ideal for those who need a temporary weight loss boost or are not candidates for surgery.

“The gastric balloon is an excellent kick-start device, particularly for those who require encouragement and direction, while the sleeve provides long-term benefits for long-term change,”

says Dr. Sheth.

Here’s why:

• Weight Loss Results:

Gastric sleeve patients lose more or less 60–70% of their excess weight in 12–18 months. The patients who have gastric balloons lose 10–15% of their body weight while the balloon is inserted for 6 months.

• Longevity of Results:

The balloon is removable and is taken out after six months. In the absence of lifestyle modifications being strictly adhered to, regain of weight is very common. In contrast, the sleeve reduces stomach capacity permanently and impacts the gut hormones, including ghrelin, that control hunger.

• Metabolic Improvements:

Gastric sleeve surgery tends to cause remission of obesity-related conditions like Type 2 diabetes, hypertension, and sleep apnea. Balloon might be useful for short-term benefit, but it does not offer sustained metabolic benefit.

• Suitability:

Gastric sleeve is indicated for individuals with a BMI of 35 or more, or those with comorbid conditions. The balloon can be considered for individuals with a BMI of 27–35 who are not suitable for surgery.

“For individuals who want a transformation for life and resolution of disease, the gastric sleeve is still the gold standard. However, the balloon can be an excellent entry point for lifestyle modification,”

explains Dr. Sheth.

Here’s what you need to be aware of:

• Nausea and Vomiting: Common in the initial days and usually managed with medications.
• Gastric Discomfort: Including bloating, acid reflux, and cramping.
• Balloon Deflation: Uncommon, but serious in the event of migration and leading to blockage.
• Esophageal or Gastric Injury: Uncommon on insertion or removal.
• Early Removal: Some individuals may not tolerate it well and may require early removal.

• Bleeding: Risk during or after surgery.
• Staple Line Leaks: Serious but rare; requires prompt treatment.
• Nutrient Deficiencies: Long-term supplementation with vitamins and minerals is necessary.
• Stricture Formation: Narrowing of the stomach sleeve.
• GERD: Acid reflux may worsen in some patients.
• Infection & Anesthesia Risks: Common to most surgeries.

“Every technique has a distinct risk profile. Knowing them makes informed, safe decisions by patients,”

claims Dr. Sheth.

Post-Gastric Balloon Lifestyle Changes

• Structured Eating: Frequent, portion-controlled meals.
• Hydration Discipline: Avoid carbonated beverages and sip water regularly.
• Exercise Routine: A minimum of 30 minutes of physical activity per day is recommended.
• Behavioral Changes: Counseling can help maintain post-balloon habits.
• Routine Monitoring: Regular check-ins with a weight loss expert.

Post-Gastric Sleeve Lifestyle Changes

• Lifelong Dietary Adjustment: Emphasis on lean proteins, small meals, and nutrient-rich foods.
• Supplementation: Daily multivitamins, iron, calcium, and B12 are essential.
• Avoid Harmful Substances: Limit alcohol and avoid smoking.
• Mindful Eating: Eat slowly, chew thoroughly, and stop at fullness.
• Regular Follow-Up: Monitor weight and nutritional levels annually.

“Surgery provides a foundation. Lifestyle is what builds lasting success,”

says Dr. Sheth.

Choosing between a gastric balloon vs gastric sleeve is not a one-size-fits-all decision. While the gastric balloon is ideal for those seeking a less invasive, non-surgical weight loss kickstart, the gastric sleeve is the go-to for long-term, transformative results.

With expert consultation, patients can weigh the pros and cons of each method based on their body type, lifestyle, and health goals. Making an informed decision with the guidance of a qualified bariatric surgeon, such as Dr. Harsh Sheth, is the first step toward lasting wellness.
