Intragastric Balloon: Minimally Invasive Weight Loss Aid

The intragastric, or gastric, balloon is a temporary, non-surgical tool designed to assist weight loss by reducing the stomach’s available volume so you feel full with smaller portions. Placed endoscopically and typically left in place for about six months, the balloon is used alongside a structured medical program that emphasizes nutrition, physical activity, and behavioral changes to support lasting results.

How the procedure works and the timeline

Placement is performed using an endoscope while the patient is sedated or under light anesthesia. A deflated silicone balloon is introduced into the stomach and then filled with saline or a gas, depending on the device. The procedure usually takes less than an hour and patients can often go home the same day.

The balloon remains in the stomach for roughly six months. During this period, patients meet regularly with healthcare professionals—dietitians, physicians, and sometimes psychologists—to practice portion control, establish healthier eating patterns, and increase physical activity. After the treatment window, the balloon is removed through a similar endoscopic technique. The aim is for the habits learned while the balloon is in place to persist after removal.

Who may benefit from an intragastric balloon

This treatment is typically recommended for adults whose body mass index (BMI) falls between 30 and 40 and who have struggled to lose weight through conventional methods like diet and exercise alone. It can also be considered for those with a BMI of 27 or greater when they have obesity-related conditions such as type 2 diabetes, hypertension, or high cholesterol.

Ideal candidates demonstrate a willingness to commit to a supervised lifestyle program and understand that the balloon is a temporary aid, not a standalone cure. Individuals with certain gastrointestinal disorders, prior complex stomach surgeries, or those who are pregnant or breastfeeding are generally excluded. A full medical evaluation, including history, physical exam, and sometimes imaging or lab tests, is required to confirm suitability.

Benefits you can expect

Because the gastric balloon avoids incisions and major surgery, it carries fewer immediate procedural risks than bariatric operations. It is reversible and removable at any point if problems arise. Many patients experience clinically meaningful weight loss—commonly between about 9 to 23 kilograms (20 to 50 pounds) over the six-month treatment period—though results vary by individual and adherence to the program.

Beyond pounds lost, balloon therapy often improves metabolic markers and obesity-related conditions. Patients may see reductions in blood pressure, cholesterol levels, and blood sugar measurements. Improved mobility, increased energy, and a higher quality of life are frequently reported. Perhaps most importantly, the balloon creates a window of opportunity to learn portion control and healthier eating behaviors that patients can carry forward after the device is removed.

Possible side effects and risks

Most people experience an adjustment period after placement. Common early symptoms include nausea, vomiting, bloating, and abdominal discomfort; these are usually worst in the first few days and ease over one to two weeks. Some patients experience reflux or indigestion during the treatment period.

Rare but more serious complications can occur, such as balloon deflation, migration leading to intestinal obstruction, stomach ulceration, or balloon-related infection. For these reasons, prompt medical attention is essential if severe pain, persistent vomiting, fever, or changes in bowel habits occur. Following the care team’s instructions and attending follow-up visits reduces the risk of complications.

Costs and what to plan for

Costs vary by country, clinic, balloon type, and the comprehensiveness of the program offered (including counseling and follow-up). Typical total prices in many markets fall roughly between six and nine thousand US dollars, which usually covers insertion, the device itself, removal, and routine follow-up care. Insurance coverage is limited, as many insurers view the procedure as elective, though financing or payment plans may be available through some providers.

Prices are estimates based on available information and may change. Independent research is recommended before making financial decisions.

In addition to the quoted procedure costs, consider expenses for pre-procedure medical tests, prescription medications to manage early symptoms, nutritional supplements if recommended, and any extended counseling sessions.

Making the decision

The intragastric balloon is a useful option for individuals seeking a less invasive alternative to bariatric surgery who need structured support to lose weight. It works best when paired with a committed, medically supervised lifestyle program and realistic expectations about the temporary nature of the device. Candidates should weigh the potential for meaningful weight loss and health improvements against the cost and possible side effects.

Discussing goals, medical history, and lifestyle with an experienced clinician will help determine whether this approach fits your situation. If selected, the device can provide a valuable period of support to build sustainable habits that contribute to long-term weight management.
