The gastric balloon procedure is a temporary, non-surgical treatment for obesity that helps you lose weight by reducing the volume of your stomach. Unlike traditional bariatric surgery, this method does not require incisions or permanent anatomical changes, making it a popular choice for those seeking a less invasive intervention.
By occupying space in the stomach, the balloon helps you feel full faster and stay satiated longer, allowing for a gradual and sustainable reduction in body weight.
What You Need to Know
- The Procedure: A doctor uses an endoscope to insert a deflated silicone balloon through the mouth and into the stomach.
- The Fill: Once in place, the balloon is filled with a saltwater (saline) solution until it is roughly the size of a grapefruit.
- Duration: The balloon typically stays in the stomach for six months before being deflated and removed via the same endoscopic method.
- Results: Most patients lose between 10% to 15% of their total body weight during the six-month program.
Who is a Candidate?
A gastric balloon may be a suitable weight loss option for adults who:
- Have a Body Mass Index (BMI) between 30 and 40.
- Have been unable to achieve significant weight loss through diet, exercise, and medication alone.
- Seek a less invasive alternative to surgeries like Gastric Sleeve or Gastric Bypass.
- Need to lose weight quickly before a major medical event, such as a joint replacement or fertility treatments.
The Procedure: Step-by-Step
The insertion is an outpatient, minimally invasive procedure that takes about 15 to 20 minutes:
- Sedation: You are sedated to ensure comfort throughout the process.
- Endoscopic Check: The doctor uses an endoscope (a thin camera tube) to inspect the esophagus and stomach for ulcers or hernias.
- Placement: A catheter carrying the deflated balloon is guided into the stomach.
- Inflation: The balloon is filled with saline. Once full, the catheter is detached, and the balloon’s internal valve seals it.
- Recovery: Most patients go home the same day once the sedation wears off.
Side Effects and Recovery
During the first few days, it is common to experience nausea, vomiting, or stomach cramps. Doctors usually prescribe anti-nausea medication and Proton Pump Inhibitors (PPIs) to manage acid reflux, which can occasionally worsen after placement.
Most patients find that their stomach adjusts to the balloon within a week. While rare, serious complications can include spontaneous balloon deflation or over-inflation, both of which require immediate medical attention.
Long-Term Weight Success
For the first two weeks following insertion, patients follow a liquid-only diet before transitioning back to solid foods. The gastric balloon is most effective when used as part of a comprehensive program that includes:
- Medical Nutrition Therapy: Working with a dietitian to build new eating habits.
- Behavioral Therapy: Addressing the psychological aspects of eating and hunger.
- Maintenance: Establishing an exercise routine to prevent weight regain after the balloon is removed at the six-month mark.
