The patient adheres to a diet after placing the stomach balloon, and this system includes eating fluids on the first day after the operation, followed by eating fluids and soups for a week after the operation, then eating pureed foods, and the patient can eat natural foods after that, but through a diet determined by the nutritionist in order not to gain back lost weight again.
Gastric Balloon
The gastric balloon and smart capsule for weightloss are non-surgical weight loss methods that work by occupying part of the stomach, helping patients feel full after eating a smaller amount of food.
These procedures do not involve removing part of the stomach or making surgical incisions. Therefore, they may be suitable for people with a limited or moderate amount of excess weight who need additional support alongside changes to their diet and lifestyle.

What Is a Gastric Balloon?
A gastric balloon is a medical balloon that is inserted into the stomach through the mouth using an endoscope. It is then filled with sterile fluid to occupy part of the stomach.
The presence of the balloon reduces the space available for food and helps the patient feel full after eating a smaller meal. It may also slow stomach emptying, allowing the feeling of fullness to last longer in some patients.
The balloon is placed without surgical incisions or the removal of any part of the stomach. The procedure is usually performed under mild sedation with local anesthesia to the throat rather than general anesthesia. Placement normally takes around 20 to 30 minutes, and the patient can return home on the same day after their condition is confirmed to be stable.
What Is a Smart Capsule?
The smart capsule for weight loss, also known as the gastric capsule, is a swallowable capsule that aids in weight loss. It is an evolution of the traditional gastric balloon.
Instead of inserting the balloon with an endoscope, the patient swallows a small capsule connected to a thin tube under the supervision of the doctor. An X-ray is then performed to confirm that the capsule has reached the stomach. It is filled with fluid until it takes the shape of a balloon, after which the tube is removed.
Placing the capsule does not usually require anesthesia or endoscopy, and the process takes only a few minutes.
The capsule normally remains inside the stomach for approximately 16 weeks. Its valve then opens automatically, allowing the fluid to leave the capsule. The empty capsule passes naturally through the digestive system in most cases. In rare cases, medical or endoscopic intervention may be required to remove it.
How Does a Gastric Balloon or Capsule Help with Weight Loss?
The gastric balloon andsmart capsule work mainly by reducing the amount of food a person can eat during a single meal.
When the balloon or capsule occupies part of the stomach, the space available for food is no longer the same as before. As a result, the patient feels full after eating a smaller amount of food and consumes fewer calories each day. The body then begins to rely on some of its stored fat for energy.
To explain this more simply, a person may be accustomed to eating a very large meal containing approximately one kilogram of food. After placing the balloon or capsule, they may find that they feel full after eating around 300 grams.
Beyond Reducing Food Intake
The period during which the gastric balloon or smart capsule remains inside the stomach may also help the patient retrain their eating habits.
For example, during a traditional diet, a person may follow a specific meal plan but still feel the desire to eat dessert after finishing a meal. When sweets are repeatedly added to the diet, the additional calories can make weight loss more difficult and may even lead to further weight gain.
With the capsule or balloon, the patient feels full after eating a smaller amount of food. This may make it easier to control both the size of the meal and the desire to eat more afterward.
However, the balloon and capsule are only tools. They cannot choose the type of food on behalf of the patient. A person can still eat small amounts of sweets or high-calorie foods and fail to lose weight at the expected rate.
Therefore, one of the main goals of the treatment period is to learn how to control:
- Meal sizes.
- Food choices.
- Sweets and snacks.
- Emotional eating or eating without feeling physically hungry.
- Meal times.
- Daily physical activity.
The Difference Between a Gastric Balloon and a Smart Capsule
The gastric balloon and smart capsule share the same main purpose: occupying part of the stomach to help the patient eat smaller amounts of food. However, they differ in their placement method, how long they remain in the stomach, and how they are removed or passed from the body.
Traditional Gastric Balloon
- It is inserted through the mouth using an endoscope.
- Mild sedation is usually used during the procedure.
- The doctor fills the balloon with fluid after placing it inside the stomach.
- The duration depends on the type of balloon, with some common types remaining in the stomach for approximately six months.
- It is removed through an endoscopic procedure after the recommended period.
Smart Capsule
- It is swallowed like a medication capsule under the supervision of the doctor.
- It does not usually require endoscopy or anesthesia for placement.
- An X-ray is performed to confirm that it has reached the stomach.
- It is filled with fluid through a thin tube.
- The Allurion Capsule remains in the stomach for approximately 16 weeks.
- It empties automatically and passes naturally from the body in most cases.
The doctor determines whether one of these options, or a completely different procedure, is more appropriate based on the patient’s condition, medical history, ability to swallow the capsule, and the amount of weight they need to lose.
Steps of the Gastric Balloon Procedure
The traditional gastric balloon is placed through the following steps:
- The patient undergoes a medical assessment and the required tests to confirm that the procedure is suitable for their condition.
- The patient receives a sedative to help them relax, along with local anesthesia to the throat before the endoscope is inserted.
- The doctor examines the esophagus and stomach with the endoscope to ensure that there are no problems preventing balloon placement.
- The balloon is inserted into the stomach through the mouth.
- The doctor fills the balloon with sterile fluid according to its type and the required volume.
- The patient is monitored for a short period after the procedure before returning home.
The gastric balloon placement procedure usually takes approximately half an hour. The patient may remain at the center for one or two hours afterward until the effects of the sedative wear off and the medical team confirms that they are tolerating the balloon.
Steps of the Smart Capsule Procedure
Placing the smart capsule is simpler:
- The patient swallows the capsule connected to a thin tube under the doctor’s supervision.
- An X-ray is performed to confirm that the capsule has reached the stomach.
- The doctor fills the capsule with fluid through the tube.
- Another X-ray is performed to confirm that the balloon is properly filled and positioned.
- The tube is removed, while the capsule remains inside the stomach.
The patient can leave the clinic after the capsule is placed if their condition is stable. They must follow the medication and dietary instructions provided by the doctor.
Benefits of the Gastric Balloon and Gastric Capsule
The gastric balloon or capsule may offer several benefits to suitable patients, including:
Weight Loss Without Surgery
The procedure does not require surgical incisions, the removal of any part of the stomach, or changes to the route of food through the digestive system.
Feeling Full After Eating Less
The balloon occupies part of the stomach, helping the patient control meal sizes and reduce their daily food intake.
Quick Return to Daily Activities
The patient can return home on the same day. Most patients gradually resume their normal activities after the initial symptoms improve.
An Opportunity to Change Eating Habits
The period during which the balloon remains inside the stomach provides a practical opportunity to learn how to eat smaller meals, improve food choices, and manage emotional eating or frequent cravings for sweets.
A Temporary and Reversible Option
The balloon does not permanently change the shape of the stomach. The traditional balloon is removed, while the capsule passes naturally from the body in most cases after completing its recommended period.
How Much Weight Can You Lose with a Gastric Balloon?
Results vary from one patient to another depending on their starting weight, the type of balloon, how long it remains in the stomach, their diet, physical activity, and commitment to follow-up.
Some patients may lose approximately 10 to 20 kilograms. The result can also be expressed as a percentage of total body weight. The aim of procedures such as the balloon and capsule is to achieve limited or moderate weight loss. They are not intended to help patients with severe obesity lose all of their excess weight.
Smart Capsule and Intragastric Balloon Side Effects
Although the gastric balloon and capsule are non-surgical procedures, they are not completely free from side effects or potential complications.
A temporary solution: After the balloon is removed, the stomach remains unchanged surgically. If the patient returns to their previous meal sizes and unhealthy habits, they may regain the weight.
Nausea, vomiting, and stomach cramps: Some patients may experience nausea, vomiting, abdominal pain, or stomach cramps during the first few days. These symptoms usually improve as the body adjusts to the balloon.
Difficulty tolerating the balloon: In some cases, the patient may be unable to adapt to the balloon despite taking the prescribed medication. The balloon may then need to be removed before the end of its recommended period.
Possible balloon deflation or leakage: In rare cases, the balloon may leak or deflate. Some types contain a dye that can cause the urine to turn blue or green if leakage occurs. The patient should contact the doctor immediately if this happens.
Therefore, the procedure should be performed under the supervision of a doctor experienced in gastric balloon and capsule procedures to ensure proper placement and reduce the risk of side effects and complications.
Is a Gastric Balloon or Capsule Suitable for Me?
You Have a Moderate Amount of Excess Weight
Some types of gastric balloons and capsules are used for adults with a body mass index between 30 and 40. The procedure may also be suitable for a person who needs to lose approximately 10, 15, or 20 kilograms, depending on their weight and overall health.
Previous Weight Loss Methods Have Not Produced Sufficient Results
The gastric balloon or capsule may be considered if you have tried to lose weight through dietary changes, exercise, or medically supervised weight loss programs but have not achieved sufficient or sustainable results. As continuing to live with excess weight may increase the risk of health problems such as type 2 diabetes, high blood pressure, sleep apnea, joint pain, and cardiovascular disease. Losing weight can therefore be important not only for appearance, but also for improving overall health and reducing obesity-related risks.
You Eat Large Amounts of Food
The balloon may help a person whose main problem is eating large meals because it allows them to feel full after consuming a smaller amount.
However, if the main problem is regularly consuming high-calorie drinks or sweets, the balloon will not prevent this on its own. Changing eating behavior will remain necessary.
You Are Looking for a Temporary Solution
The balloon may suit someone who gained weight during a particular period or because of specific circumstances and needs a tool to help them return to a healthier weight and develop better eating habits.
You Are Ready to Change Your Lifestyle
The success of the balloon does not depend only on the period during which it remains inside the stomach. You must be prepared to follow a balanced diet, reduce calorie intake, exercise regularly, and continue follow-up after the balloon is removed or the capsule passes from the body.
When Is the Gastric Balloon or Capsule Not Suitable?
The procedure may not be suitable for patients with certain conditions, including:
- Active stomach ulcers.
- Certain esophageal conditions or difficulty swallowing.
- Certain cases of hiatal hernia.
- Previous surgeries involving the stomach or esophagus.
- Certain digestive motility disorders.
- A history of intestinal obstruction or certain intestinal surgeries.
- An inability to commit to follow-up or make the required behavioral changes.
The final decision is made by the specialist after assessing the patient’s individual condition.
Why Do Gastric Balloon or Capsule Procedures Fail for Some Patients?
A limited result does not always mean that the balloon or capsule is ineffective. In many cases, the reason is that the procedure was chosen for a patient who was not suitable for it.
A patient may be afraid of bariatric surgery even though they need to lose 40 or 50 kilograms. They may choose the capsule because they consider it the easier option.
After the treatment period ends, the patient may lose some weight but fail to achieve the result they expected. They may then believe that the capsule itself failed.
The problem in this situation is not necessarily the capsule. It is the use of a procedure designed for limited weight loss in a patient who requires a stronger and more sustainable treatment.
Therefore, the decision should not be based only on fear of surgery. It should take into account the amount of excess weight, the degree of obesity, associated medical conditions, and the realistic results expected from each procedure.
When Is Bariatric Surgery More Suitable?
A bariatric procedure, such as sleeve gastrectomy, mini sleeve gastrectomy, or gastric bypass, may be more appropriate in the following cases:
- A very significant amount of excess weight.
- Severe or morbid obesity.
- Obesity-related medical conditions that require greater and more sustainable improvement.
- Failure of non-surgical methods to achieve sufficient results.
- Repeated weight regain after temporary weight loss attempts.
- The need to lose a large percentage of excess weight.
