In recent years, one of the methods frequently used in obesity treatment has been gastric balloons. Prepared from special materials and designed to help patients feel full with less food intake, gastric balloons stand out as treatment techniques with high success rates. With varying durations of stay in the stomach, gastric balloons offer an effective solution for patients seeking non-surgical treatment. The reason it is called a 6-month balloon is that it remains in the stomach for 6 months and is then removed.
It should also be noted that the types of gastric balloons used today may vary, and the most suitable option for the patient can easily be determined by the physician. One of these types is the 6-month gastric balloon. Medsil and Bariglobe gastric balloons are produced in Russia and have been used for a long time both in our country and in many parts of the world. They are among the most commonly preferred types in Türkiye. We will discuss who this procedure is suitable for, how it is performed, and other frequently asked questions. First, let’s address the commonly asked question: is it safe?
Is the 6-Month Gastric Balloon Safe?
6-month gastric balloons have been used in obesity treatment for a long time. Of course, like other gastric balloon procedures, there are some risks of complications. However, choosing an experienced physician and following medical recommendations significantly reduces these risks. Overall, these gastric balloons are considered safe and can be preferred with confidence. Before the procedure, you should consult your doctor to determine whether you are a suitable candidate.
How Is the Gastric Balloon Procedure Performed?

First of all, it should be noted that patients do not feel pain or discomfort during the placement of the 6-month gastric balloon. This is because sedoanalgesia (a mild sedation method) is applied before the procedure. This ensures a very comfortable process for the patient. Endoscopy is used during the procedure. The balloon is placed into the stomach in a deflated state and, due to its small size, can be easily inserted through the mouth. It is then inflated with a predetermined amount of fluid depending on the patient’s condition. This allows the balloon to occupy space in the stomach, enabling patients to feel full with smaller portions.
The 6-month gastric balloon remains in the stomach for 6 months. At the end of this period, it must be removed. Removal is also performed endoscopically, meaning both placement and removal are non-surgical. No incisions or stitches are required, and there is no need for extended clinical rest. After removal, patients who continue with a proper diet and exercise program can maintain their weight loss. During the time the balloon remains in the stomach, patients naturally begin consuming less food.
Who Is the 6-Month Gastric Balloon Suitable For?
Although gastric balloon treatment has a high success rate, it is not suitable for everyone. To undergo the 6-month gastric balloon procedure, patients are expected to have a body mass index between 20 and 40. Additionally, a medical examination and certain tests are required beforehand. It is not suitable for individuals with hiatal hernia, those who have undergone previous stomach or esophageal surgery, or those with gastric ulcers, as it may pose serious risks. In such cases, alternative treatment options should be considered.
Pregnant individuals cannot undergo this procedure. It is also not recommended for women planning to become pregnant within the next 6 months. Eligibility is determined after medical evaluation and necessary tests.
How Much Weight Can Be Lost with a 6-Month Gastric Balloon?
The amount of weight loss varies from person to person. Factors such as adherence to a healthy diet, following a diet plan, engaging in exercise, and metabolic rate all influence weight loss. Therefore, the results after a 6-month gastric balloon or other gastric balloon procedures may differ.
In general, weight loss is estimated to range between 20% and 40%. Weight loss may be more rapid during the first 3 months and slow down afterward, which is completely normal. The main goal of this treatment is to help patients develop healthy eating habits and reduce portion sizes. After 6–8 months, the balloon must be removed, and patients should maintain the eating habits they have developed. Otherwise, weight regain may occur.
Gastric balloon procedures do not guarantee permanent weight loss. They only facilitate weight loss. If patients return to their previous eating habits after removal, regaining weight is highly likely.
When Does Weight Loss Start After a 6-Month Gastric Balloon?

Patients usually notice that they start eating less and feel full more quickly shortly after the balloon is placed. Therefore, weight loss begins soon after the procedure. It may be rapid at first and then slow down, which is normal. There is no need to wait to start losing weight. If patients follow their diet programs, weight loss begins immediately.
Are There Any Side Effects of the Medsil Gastric Balloon?
After placement, some patients may experience mild side effects such as nausea, vomiting, retching, and, in rare cases, mild abdominal pain. However, not all patients experience these symptoms. These side effects typically resolve on their own within 3 to 7 days. Another possible issue is intolerance to the balloon, usually indicated by severe retching and vomiting. In such cases, the balloon must be removed. Patients should inform their doctor so that appropriate intervention can be performed promptly.
Can the Gastric Balloon Burst?
A common concern is whether the balloon can burst. These balloons are made from special materials, and the risk of bursting is extremely low. No cases of rupture have been reported with the Medsil 6-month gastric balloon. Patients should not worry about this. The primary risk is leakage, but with advanced technologies, even this risk has been reduced to a minimal level.
Problems After Gastric Balloon Placement and Their Solutions
Nausea: Around 10% of patients may experience nausea on the evening of the procedure. Special medications are prescribed, and dietitians provide an appropriate diet plan.
Vomiting: Although rare, it can be uncomfortable. If medications do not help, intravenous treatment may be required.
As a clinical obesity team, we place great importance on the first three days after balloon placement, as proper management during this period is crucial for patient comfort and success.
