The gastric balloon is one of the most effective non-surgical treatments for weight loss, indicated for people with excess weight or obesity who are seeking a less invasive solution than bariatric surgery. It is a temporary medical device placed in the stomach through endoscopy, which occupies space and reduces gastric capacity, promoting an earlier and longer feeling of fullness. In the AEGER Prima Clinic, in Lisbon, the gastric balloon placement is performed by experienced gastroenterologists, integrated into a nutritional and clinical follow-up program that maximizes results and supports the patient in all stages of the process.
What is the gastric balloon and when is it indicated?The gastric balloon is a soft silicone device inserted empty into the stomach through an endoscope (without the need for surgery or incisions) and later filled with saline solution or gas, until it reaches the appropriate volume. This volume occupies part of the gastric space, which reduces the amount of food needed to reach fullness. It is especially indicated for people who:
The gastric balloon is not indicated for all people. Cases of active inflammatory bowel disease, large hiatal hernia, previous gastric surgeries, or certain psychiatric conditions may contraindicate the procedure, which is why prior medical evaluation is indispensable.How is the procedure performed at the AEGER Prima Clinic?The gastric balloon placement is done by upper digestive endoscopy, usually under light sedation, and has a duration of approximately 20 to 30 minutes. The gastroenterologist introduces the deflated balloon through the mouth to the stomach, filling it with sterile saline solution to the previously defined volume. No incisions, stitches, or prolonged hospitalization are necessary; most patients return home on the same day, with a short period of rest. The balloon remains in the stomach for a period usually between 6 and 12 months, depending on the type of device used, and is then removed through a new endoscopic procedure. Before placement, a comprehensive evaluation consultation is performed, where the doctor analyzes the medical history, necessary complementary exams (such as upper digestive endoscopy and laboratory tests), and defines, together with the patient, the nutritional follow-up plan that accompanies the entire treatment.
Without incisions, scars, or need for prolonged hospitalization.
Most patients resume daily activities in a few days.
Associated with an adequate nutritional plan, it can contribute to significant weight loss in the first months.
Unlike bariatric surgery, the balloon is removed at the end of treatment, without permanent changes to the stomach's anatomy.
It serves as a catalyst for the adoption of healthier and more sustainable eating habits in the long term.
In the AEGER Prima Clinic, the treatment is accompanied by nutritionists and the clinical team, increasing the likelihood of lasting results.
Results vary from person to person and depend on factors such as adherence to the nutritional plan, level of physical activity, and individual characteristics of each patient. No specific result can be guaranteed in advance.
The doctor analyzes the complete medical history, including previous illnesses, surgeries, and ongoing medication, to confirm that the procedure can be performed safely.
The weight loss objectives and realistic expectations regarding the results are discussed, clarifying that the gastric balloon is a support tool and not an isolated solution.
A prior upper digestive endoscopy, laboratory tests, and, in some cases, nutritional or psychological evaluation may be requested to ensure that the patient meets the appropriate conditions for treatment.
A regular nutritional and clinical follow-up plan is established during the entire period the balloon remains in place, adjusted to the specific needs of each patient.
The placement procedure is performed under sedation, so there is no pain during the process. In the first few days after placement, it is common to feel nausea, a feeling of bloating, or mild abdominal discomfort, as the body adapts to the device, symptoms that tend to decrease progressively.
The balloon remains in the stomach for a period that usually varies between 6 and 12 months, depending on the type of device used, and is then removed through an endoscopic procedure.
Weight loss varies significantly between patients and depends on adherence to the nutritional and exercise plan associated with it. The doctor and nutrition team will provide a realistic estimate, adjusted to the individual case, during follow-up.
No, in most cases. Both the placement and removal are performed on an outpatient basis, with the patient returning home on the same day.
People with certain conditions, such as active inflammatory bowel disease, large hiatal hernia, previous gastric surgeries, or certain psychiatric conditions, may not be suitable candidates. This evaluation is made individually during the prior consultation.
After removal, nutritional follow-up should continue, in order to consolidate the eating habits adopted during treatment and support the maintenance of weight lost in the long term.
It is considered a safe procedure when performed by experienced professionals in an adequate clinical setting. As with any medical procedure, there are risks and possible side effects, which will be explained in detail during the evaluation consultation, allowing for an informed decision.
