A gastric balloon is a minimally invasive weight loss treatment in which a balloon is placed inside the stomach to help create a feeling of fullness and reduce food intake.
If your Body Mass Index (BMI) is above 30, a gastric balloon may be an effective option for achieving long-term weight loss and helping manage conditions such as type 2 diabetes or high blood pressure.
By lowering body weight before an operation, the balloon can also help reduce the risks linked to surgery in overweight patients.
Using an endoscope for guidance, a soft silicone balloon is inserted through the mouth and into the stomach while deflated. Once it is in the correct position, it is filled with a sterile saline solution.
The procedure is carried out under sedation and usually takes about 20 to 30 minutes. In most cases, patients are able to return home on the same day.
Before having an intragastric balloon placed, the patient will receive detailed instructions on how to prepare for the procedure.
This may include laboratory tests and medical examinations. Patients may also need to follow certain dietary restrictions related to food, drinks, and medication. In some cases, they may be advised to begin a physical activity programme as part of the preparation process.
After the gastric balloon procedure, most patients are able to return home within one or two days.
The post-treatment diet usually begins with liquids, then gradually progresses to soft foods, and finally to solid meals after around one to two weeks.
Most people can return to work within two to three days, depending on how quickly the stomach adjusts and on the nature of their job.
Regular exercise is recommended to support recovery and help patients return to a normal routine more quickly.
The balloon is usually removed by endoscopy after six to nine months.
On average, patients lose more than one-third of their excess body weight. Noticeable weight loss is often seen within the first three months, with an average reduction of 30 to 60 pounds after six months.
Maintaining a healthy low-calorie diet and regular exercise after the balloon is removed can help preserve the achieved weight loss.
Some patients may experience discomfort or nausea soon after an intragastric balloon is inserted, but these symptoms are usually temporary and tend to disappear within a few days.
Although uncommon, there are also some more serious potential risks. One of them is balloon deflation, which may cause the balloon to move through the digestive tract and potentially create a blockage.
Other possible complications include balloon overinflation, acute pancreatitis, ulcer formation, or a perforation in the stomach wall. While these side effects are rare, they may require surgical treatment if they occur.
The swallowable 4-month gastric balloon, also known as the gastric balloon pill, is an ideal option for patients who prefer to avoid surgical treatment.
The procedure takes only around 10 to 15 minutes to complete. It requires just a single visit and stays in the stomach for four months to help support effective weight loss. After that period, the balloon passes naturally through the body in the stool.
