Who Are Suitable for Gastric Balloon? What Kinds of Gastric Balloon Are There?

Who is eligible for a gastric balloon is a topic frequently discussed by individuals who are struggling with excess weight. Although the gastric balloon procedure has been preferred for a long time, it must be performed by a highly experienced and meticulous surgeon.

This procedure should not be confused with other obesity surgeries. In gastric balloon application, the endoscopic method is used. With the help of an endoscope, the stomach is reached through the mouth, and a deflated balloon is placed into the stomach. Then the balloon is inflated to create a feeling of fullness.

No incision is made during the placement or inflation of the balloon, and therefore no stitches are required afterward. For this reason, it is considered an ideal option for those who suffer from obesity but are afraid of surgery. We will discuss who is suitable for this procedure and who is not, but first, let’s review the advantages of the gastric balloon.

What Are the Advantages of the Gastric Balloon?

The gastric balloon procedure, which has helped many patients achieve their ideal weight, offers numerous advantages. Just like the question of who is eligible for a gastric balloon, these benefits are also very important. First of all, the most significant advantage is that it preserves the anatomy of the stomach. No part of the stomach is removed. A balloon is simply placed inside, inflated, and removed after approximately 6 or 12 months using the same method. Therefore, the natural structure of the stomach remains unchanged. Other advantages can be listed as follows:

• No surgery is required. The procedure is completed within 15 to 20 minutes under endoscopy.
• Since there is no surgical intervention, there is no recovery period.
• It enables safe weight loss.
• If an unexpected situation occurs, the balloon can be removed quickly and easily.
• No interference is made with other organs or body systems.
• Patients can easily adapt to daily life after the procedure.
• The goal is to reduce food intake by creating fullness, which can support long-term healthy eating habits.
• Following doctor and dietitian recommendations allows for rapid weight loss.
• It helps control portion sizes by reducing hunger.
• It is more economical compared to many obesity surgery methods.
• If necessary, the procedure can be repeated in the future.
• Weight loss of around 30 kg within 6–12 months is possible.
• If lifestyle changes are maintained, weight loss can continue even after removal.
• It is ideal for those who are afraid of surgery.

Who Are Candidates for Gastric Balloon?

Individuals who fail to lose weight despite diet and exercise are suitable candidates. In addition, the following groups can also be considered as answers to the question who is eligible for a gastric balloon:

• People with obesity-related conditions such as diabetes or hypertension
• Patients who are overweight but not yet suitable for obesity surgery
• Patients with a body mass index between 35 and 40
• Patients who are afraid of undergoing surgery

In some cases, gastric balloon treatment is used before surgery to reduce risks. Once a certain weight is reached, surgical planning can be done.

Who Should Not Receive a Gastric Balloon?

There is no strict age limit, but it is generally not recommended for children under 10 unless absolutely necessary. It is also not suitable in the following cases:

• Inflammatory diseases of the gastrointestinal tract
• Hiatal hernia
• Liver failure
• Bleeding disorders or serious clotting issues
• Previous bariatric or gastrointestinal surgery
• Esophageal motility disorders
• Psychiatric conditions

For these individuals, alternative weight loss methods should be considered.

What Are the Types of Gastric Balloons?

Patients are also curious about the types of gastric balloons as much as who is eligible for a gastric balloon. These medical products can be classified in several ways.

Fluid-Filled Balloons

After placement, a colored liquid (methylene blue mixed saline) is injected. These balloons usually have a volume of 400–500 ml. If leakage occurs, urine color changes to blue or green, making detection easy.

Air-Filled Balloons

Air is injected using a catheter. They may have a larger volume but do not create weight. Leakage cannot be easily detected.

Gastric balloons can also be categorized based on adjustability:

Adjustable Balloons

These are fluid-filled and allow volume adjustment depending on weight loss progress.

Non-Adjustable Balloons

These have a fixed volume and cannot be modified after placement.

Is the Gastric Balloon Permanent?

Gastric balloons are not permanent. Some patients think they remain in the stomach for life, but modern balloons are designed for 6 or 12 months and must be removed afterward.
