When it comes to weight loss, not everyone is ready — or able — to undergo surgery. That’s where intragastric balloons come in. These non-surgical, temporary devices offer an alternative path to shedding excess weight for those who’ve struggled with traditional methods like diet and exercise alone.
The global intragastric balloons market size was valued at $32.2 million in 2023, and is projected to reach $115.3 million by 2033, growing at a CAGR of 13.6% from 2024 to 2033.
What Is an Intragastric Balloon?
An intragastric balloon is a soft, expandable device that is inserted into the stomach and then filled with saline or gas. Its primary purpose? To take up space in the stomach and help patients feel fuller, faster — ultimately leading to reduced food intake.
Unlike bariatric surgeries like gastric bypass or sleeve gastrectomy, balloon placement doesn’t involve altering the digestive system. It’s minimally invasive, usually done via endoscopy or even swallowed in capsule form (depending on the type), and often completed in under 30 minutes.
How Does It Work?
Once the balloon is inflated in the stomach, it stays in place for about six months, though some newer models may remain for up to a year. During this time, patients typically work closely with a nutritionist or medical team to develop healthier eating habits and lifestyle changes.
The balloon’s presence helps limit portion sizes and curbs hunger, making it easier to stick to a calorie-controlled diet. On average, patients lose between 10–15% of their total body weight during the balloon period.
Who Is a Candidate?
Intragastric balloons are generally recommended for individuals who:
- Have a BMI of 30–40
- Haven’t been successful with diet and exercise alone
- Are not ready or eligible for bariatric surgery
- Are committed to long-term lifestyle changes
They are not suitable for people with prior stomach surgeries, large hiatal hernias, or certain gastrointestinal conditions.
Pros and Cons

Final Thoughts
Intragastric balloons aren’t a magic fix — but they can be a powerful jumpstart for people serious about losing weight and improving their health. With medical guidance and long-term lifestyle changes, they offer a bridge between traditional weight loss efforts and more invasive procedures.
