The Gastric Balloon: What It Is and What to Ask
A plain-language guide to the intragastric balloon for people exploring weight-management options in Los Angeles and surrounding areas.
What Is a Gastric Balloon?
A gastric balloon, also called an intragastric balloon, is a soft, expandable device a doctor places inside your stomach without making any cuts in your skin. The doctor uses a thin, flexible tube called an endoscope to guide the deflated balloon through your mouth and into your stomach. Once it is in position, the balloon is filled with a saline solution or gas, so it takes up space inside your stomach.
Because the balloon occupies space, many people feel full after eating smaller amounts of food than they normally would. The device is temporary. Most gastric balloons are designed to be removed after about six months, though the timing depends on the specific device and your doctor's clinical judgment.
The gastric balloon is not bariatric surgery. No incisions are made, no staples are placed, and nothing in your digestive system is permanently altered. That sets it apart from weight-loss operations like the gastric sleeve, gastric bypass, or adjustable gastric band.
How Does It Compare to Weight-Loss Surgery?
Weight-loss surgery, also called metabolic and bariatric surgery, makes lasting changes to your digestive system. Some operations reduce the size of your stomach so you feel full sooner. Others change how your small intestine absorbs calories from food and drink. These structural changes are generally long-term or permanent.
The gastric balloon, by contrast, is a temporary, removable device. It does not cut, staple, or reroute any part of your digestive tract. Because of this, it is sometimes considered by people who want a less invasive first step, or who do not currently meet the clinical criteria for bariatric surgery. Your doctor is the right person to explain which option, if any, may fit your situation.
Keep in mind that even without surgery, the gastric balloon still involves a medical procedure, sedation, and careful follow-up care. It also still carries real risks, which are listed below.

Who May Be Considered a Candidate?
Eligibility for any weight-management procedure depends on many personal health factors. For bariatric surgery in general, people with a BMI of 35 or higher are often considered, because obesity can be hard to treat with diet and exercise alone at that level. For people with a BMI of 30 to 35 who have hard-to-control type 2 diabetes, surgery may also be discussed as an option.
Gastric balloons are often considered for adults whose BMI may fall in a lower range and who are looking for support beyond diet and exercise alone. Eligibility requirements vary by the specific device and by the guidelines your care team follows. No outcome is promised with any device or procedure. Your doctor will review your full health history before making any recommendation.
What Are the Risks?
Like any medical procedure, the gastric balloon carries real risks. Common side effects in the days after placement often include nausea, vomiting, stomach cramping, and abdominal discomfort. These often ease as the body adjusts, but they can be significant for some people.
More serious risks can include:
- The balloon deflating early and moving out of place, which can cause a blockage in the digestive tract
- Gastric ulcers or irritation of the stomach lining
- In rare cases, perforation of the stomach or esophagus
- Weight returning after the balloon is removed if lifestyle habits do not change
If you have severe abdominal pain, difficulty breathing, blood in your vomit, or other signs of a serious problem after a balloon placement or removal, call 911 or go to the nearest emergency room immediately.
Questions to Ask Before You Decide
Before moving forward with any weight-management option, it helps to bring a list of questions to your appointment. Here are some to consider:
- Am I a good candidate for a gastric balloon based on my full health history?
- What does the FDA say about the specific balloon device being used?
- What side effects are most common during the first week after placement?
- What diet and lifestyle support will be available during and after treatment?
- What happens if the balloon deflates before the removal date?
- Would weight-loss surgery be a better fit for my long-term goals?
In California, you can verify that a physician or surgeon holds a valid, current license by visiting the Medical Board of California at mbc.ca.gov and using their license lookup tool.
Weight-management decisions are personal and complex. No single option is right for everyone. Gathering information and talking openly with your care team are good first steps toward making a decision that fits your health needs.
Frequently asked questions
- Is the gastric balloon the same as bariatric surgery?
- No. The gastric balloon is placed and removed without incisions, so it is not bariatric surgery. Bariatric surgery makes lasting changes to the stomach or small intestine. A doctor can help you understand which approach, if any, is appropriate for your personal health needs.
- How long does a gastric balloon stay in place?
- Most gastric balloons are designed to remain in the stomach for about six months before being removed. The exact timeline depends on the specific device your doctor uses and your individual situation. No outcome is promised, and your care team will monitor you throughout the process.
- What symptoms after a balloon procedure should send me to the emergency room?
- Call 911 or go to the nearest emergency room right away if you experience severe abdominal pain, difficulty breathing, blood in your vomit, or any other sudden, serious symptoms. Do not wait if something feels seriously wrong.
- How do I check a doctor's license in California?
- You can verify a physician's or surgeon's license using the license lookup tool on the Medical Board of California website at mbc.ca.gov. This lets you confirm they hold a valid, current California license before your first appointment.
