Gastric balloon is a non-surgical weight loss procedure designed to help patients lose weight by placing a soft balloon inside the stomach to reduce stomach capacity and promote early satiety. The balloon is inserted endoscopically or swallowed depending on the type of balloon used. Once inside the stomach, the balloon is filled with saline solution or gas, occupying space and reducing the amount of food that can be consumed. Gastric balloon is considered a temporary and reversible weight loss solution and is often recommended for patients who are overweight but not eligible for bariatric surgery such as gastric sleeve or gastric bypass.
The gastric balloon works by reducing stomach volume and slowing gastric emptying. Patients feel full faster and reduce portion sizes naturally. The balloon also helps patients change eating behavior, reduce snacking, and adopt healthier dietary habits. Weight loss with gastric balloon is not only due to the balloon itself but also due to medical follow-up, nutrition programs, and lifestyle changes during the treatment period.
Gastric balloon is usually recommended for patients with a Body Mass Index between 27 and 35, although it can also be used for patients with higher BMI as a pre-bariatric surgery weight loss solution. Candidates should not have stomach ulcers, severe reflux disease, previous stomach surgery, or untreated eating disorders. Patients must also be motivated to change diet and lifestyle because the balloon alone does not guarantee long-term weight loss.
There are several types of gastric balloons available today including saline-filled balloons, gas-filled balloons, swallowable balloons that do not require endoscopy for placement, and adjustable balloons that can be modified during treatment. The choice depends on patient profile, treatment duration, clinic experience, and medical recommendations.
The gastric balloon procedure usually takes between 15 and 30 minutes and is performed under sedation. Patients typically go home the same day. During the first few days after balloon placement, patients may experience nausea, vomiting, stomach cramps, and discomfort while the body adapts to the balloon. A progressive diet from liquids to soft foods and then solid foods is usually recommended.
Average weight loss with gastric balloon ranges between 10 and 20 kilograms over a period of six months depending on starting weight, diet, physical activity, and follow-up program. Some patients lose more weight while others lose less depending on adherence to dietary recommendations. The balloon is usually removed after six months although some types can remain for twelve months.
Gastric balloon is less invasive than gastric sleeve and gastric bypass because it does not require surgery or permanent anatomical changes. However, weight loss results are generally lower than with bariatric surgery. Gastric balloon is often considered a first step weight loss procedure or a temporary solution before more definitive surgery.
Possible side effects include nausea, vomiting, acid reflux, stomach cramps, balloon intolerance, balloon deflation, or early removal. Serious complications are rare but may include balloon migration or intestinal obstruction if the balloon deflates. Medical follow-up is important to monitor tolerance and progress.
The price of gastric balloon abroad depends on balloon type, clinic experience, consultation, anesthesia, follow-up program, and nutrition support included in the package. Many clinics offer packages including consultation, balloon placement, medication, and removal procedure.
Long term success after gastric balloon depends mainly on lifestyle changes after balloon removal. Patients who maintain healthy diet and physical activity habits can maintain most of their weight loss. Patients who return to previous eating habits may regain weight after balloon removal. For this reason, medical nutrition follow-up is very important.
