A gastric balloon, also known as a weight loss balloon or intragastric balloon, is a non-surgical, minimally invasive procedure used to assist with weight loss. It involves placing a soft, silicone balloon inside the stomach to create a feeling of fullness and promote portion control.

Gastric balloon procedures are typically performed as outpatient procedures, meaning patients can usually return home the same day. The procedure is generally less invasive than surgical weight loss procedures, and the recovery time is shorter.

It's important to note that the gastric balloon is considered a temporary weight loss aid. It is often recommended for individuals who have struggled with weight loss but are not suitable candidates for or do not wish to undergo bariatric surgery. The balloon is intended to be used as part of a comprehensive weight loss program that includes dietary changes, lifestyle modifications, and ongoing support from a healthcare team.

Here’s an overview of how the gastric balloon procedure works:

  1. Placement of the balloon: During the procedure, a deflated balloon is inserted into the stomach through the mouth using an endoscope, a thin flexible tube with a camera attached to it. The balloon is then filled with a sterile saline solution or gas to expand it and occupy space within the stomach.

  2. Balloon adjustment and monitoring: Once the balloon is filled, it remains in the stomach for a predetermined period, usually around 6 to 12 months. During this time, the patient works closely with a healthcare team, including dietitians and physicians, to monitor progress, make necessary adjustments, and receive guidance on lifestyle changes.

  3. Portion control and weight loss: The presence of the balloon in the stomach creates a feeling of fullness and restricts the amount of food that can be consumed. This promotes portion control, reduces calorie intake, and helps individuals develop healthier eating habits. Combined with dietary modifications and behavior changes, the gastric balloon can contribute to weight loss.

  4. Removal of the balloon: After the designated period, the gastric balloon is removed. This is typically done in a similar manner to its placement, using an endoscope. The balloon is deflated and carefully extracted from the stomach.

The gastric balloon procedure is typically recommended for individuals who are overweight or have mild to moderate obesity and have struggled with weight loss through conventional methods such as diet and exercise. It can be considered as a non-surgical alternative for weight loss before considering more invasive procedures like bariatric surgery.


Here are some common factors that may make someone a candidate for a gastric balloon:


  1. BMI range: Gastric balloons are generally suitable for individuals with a body mass index (BMI) between 30 and 40. However, this can vary depending on individual circumstances and the specific guidelines set by healthcare professionals.

  2. Weight loss attempts: The gastric balloon may be recommended for individuals who have made efforts to lose weight through diet, exercise, and lifestyle changes but have not achieved their desired results.

  3. Health conditions: Candidates for the gastric balloon should generally be in good overall health, free from significant medical conditions that could increase the risks associated with the procedure. However, this can be evaluated on an individual basis by healthcare professionals.

  4. Motivation and commitment: Success with the gastric balloon requires a strong commitment to making long-term changes in diet and lifestyle. Candidates should be motivated and willing to work closely with a healthcare team to achieve their weight loss goals.

  5. Psychological evaluation: Some healthcare providers may conduct a psychological evaluation to assess the candidate’s readiness for the procedure and their ability to cope with the physical and emotional changes that come with weight loss.

Gastric balloon procedures are performed for several reasons related to weight loss and overall health improvement. Here are some of the primary reasons why gastric balloons are done:


  1. Weight loss: The primary goal of a gastric balloon procedure is to aid in weight loss. The balloon occupies space in the stomach, creating a feeling of fullness and reducing hunger. This helps individuals eat smaller portions and make healthier food choices, leading to weight loss.

  2. Non-surgical approach: Gastric balloons offer a non-surgical alternative to weight loss when compared to more invasive procedures like bariatric surgery. For individuals who are not suitable candidates for surgery or prefer a non-surgical option, the gastric balloon provides an alternative option to help achieve weight loss goals.

  3. Preparation for bariatric surgery: In some cases, a gastric balloon may be used as a temporary measure before considering more invasive weight loss surgeries like gastric bypass or gastric sleeve. It can help individuals lose weight and improve their overall health, making them better candidates for subsequent surgical interventions.

  4. Health improvements: Weight loss achieved through a gastric balloon can lead to significant health improvements. It can help manage or resolve obesity-related conditions such as type 2 diabetes, high blood pressure, sleep apnea, and high cholesterol levels. Additionally, losing weight can improve overall cardiovascular health and reduce the risk of certain chronic diseases.

  5. Kick-starting lifestyle changes: The presence of a gastric balloon helps individuals develop healthier eating habits and portion control. It can serve as a tool to kick-start lifestyle changes and provide a foundation for long-term weight management.

WHAT they say


A gastric balloon is a soft, silicone balloon that is placed in the stomach to promote weight loss. It is inserted through the mouth using an endoscope and filled with a saline solution or gas to create a feeling of fullness and restrict food intake.

The gastric balloon is placed during a minimally invasive procedure that typically takes around 20 to 30 minutes. It is inserted into the stomach through the mouth using an endoscope and then filled with the desired fluid or gas. Once filled, the balloon remains in the stomach for a predetermined period.

The duration the gastric balloon remains in the stomach can vary but is usually between 6 and 12 months. The specific duration is determined by your healthcare professional based on your individual needs and goals.

After the placement of the gastric balloon, you will work closely with a healthcare team that includes dietitians and physicians. They will guide you through dietary changes, portion control, and lifestyle modifications to optimize your weight loss journey. Regular follow-up visits and support are typically provided throughout the duration of the balloon placement.

The amount of weight loss varies among individuals and depends on factors such as adherence to dietary and lifestyle changes, individual metabolism, and overall commitment to the program. On average, individuals can expect to lose around 25% to 35% of their excess body weight with a gastric balloon.

Like any medical procedure, there are potential risks and side effects associated with gastric balloon placement. These can include nausea, vomiting, abdominal discomfort, gastric ulcers, balloon deflation or leakage, and gastrointestinal obstruction. However, serious complications are rare, especially when the procedure is performed by an experienced healthcare professional.

In some cases, the gastric balloon may need to be removed before the predetermined period. This can occur if you experience intolerable side effects, complications arise, or if it is not providing the desired results. Your healthcare professional will evaluate your situation and make the appropriate decision.

The success of long-term weight loss after the gastric balloon is removed depends on the individual’s commitment to maintaining a healthy lifestyle. It’s important to continue following the dietary and lifestyle changes recommended by your healthcare team to maximize weight loss and maintain a healthy weight.
