Introduction
Obesity has become a global epidemic, affecting millions of people worldwide and contributing to numerous health problems, including cardiovascular diseases, diabetes, and certain types of cancer [1]. Despite the availability of various weight management strategies, many individuals struggle to achieve and maintain a healthy weight. However, recent advancements in medical technology and pharmacotherapy have paved the way for innovative approaches to weight management. One groundbreaking combination therapy is the Allurion gastric balloon coupled with the weight loss medication liraglutide. This article explores how this novel approach is redefining the concept of fullness and revolutionising the field of weight management.
The Allurion gastric balloon is a non-surgical, temporary weight-loss solution that has gained popularity in recent years [2]. This swallowable balloon is designed to occupy space in the stomach, creating a sense of fullness and reducing food intake. The balloon is placed in the stomach through a simple, outpatient procedure and remains in place for several months, promoting weight loss by limiting calorie consumption [3].
Liraglutide, on the other hand, is a glucagon-like peptide-1 (GLP-1) receptor agonist initially developed for the treatment of type 2 diabetes. However, its weight loss properties have made it an attractive option for individuals struggling with obesity [4]. Liraglutide works by mimicking the effects of the naturally occurring hormone GLP-1, which regulates appetite and glucose metabolism. By reducing hunger and increasing feelings of satiety, liraglutide helps individuals adhere to a calorie-restricted diet and achieve sustainable weight loss [5].
The combination of the Allurion gastric balloon and liraglutide offers a synergistic approach to weight management, addressing both the physical and physiological aspects of hunger and satiety. By combining the space-occupying effects of the gastric balloon with the appetite-suppressing properties of liraglutide, this innovative therapy has the potential to redefine the way we understand and treat obesity.
Understanding the Allurion Gastric Balloon
What is the Allurion gastric balloon?
The Allurion gastric balloon is a revolutionary, non-surgical weight loss device that has gained significant attention in recent years. This innovative technology offers a unique approach to weight management by providing a temporary, space-occupying solution within the stomach. The Allurion gastric balloon is a swallowable capsule that contains a deflated balloon made of durable, biocompatible materials [2]. Once the capsule reaches the stomach, the balloon is remotely inflated with a sterile saline solution, creating a feeling of fullness and reducing the available space for food intake [6].
How does it work?
The Allurion gastric balloon works by utilizing the fundamental principle of gastric volume reduction. When the balloon is inflated within the stomach, it occupies a considerable amount of space, typically around 550ml [2]. This space-occupying effect leads to a sensation of fullness, even with smaller portions of food, thereby encouraging portion control and reduced calorie intake. The presence of the balloon also slows down gastric emptying, prolonging the feeling of satiety and reducing the frequency of hunger pangs [6]. As a result, patients experience a decrease in their overall calorie consumption, leading to significant weight loss throughout the treatment.
Benefits and risks of the Allurion gastric balloon
The Allurion gastric balloon offers several benefits for individuals seeking an effective weight loss solution. One of the primary advantages of this device is its non-surgical nature. Unlike traditional bariatric surgeries, the Allurion gastric balloon does not require any incisions or anaesthesia, making it a less invasive option for patients [2]. Additionally, the procedure is quick and can be performed in an outpatient setting, allowing patients to return to their daily activities without significant downtime [6]. The temporary nature of the device, typically lasting around 16 weeks, also appeals to individuals who are hesitant to commit to permanent surgical interventions [3].
However, as with any medical intervention, the Allurion gastric balloon does come with certain risks and potential side effects. Some patients may experience discomfort, nausea, or vomiting in the initial days following the balloon placement, as their body adjusts to the presence of the device [6]. Rarely, more serious complications such as balloon deflation, intestinal obstruction, or perforation may occur, requiring prompt medical attention [3]. Patients must be fully informed about the potential risks and closely follow their healthcare provider’s instructions throughout the treatment process.
Despite these risks, the Allurion gastric balloon has shown promising results in clinical studies. A prospective, observational, open-label, multicentre study conducted by Machytka et al. demonstrated that the Elipse balloon, a similar device to the Allurion balloon, resulted in significant weight loss and improvements in obesity-related comorbidities [3]. As research continues to validate the efficacy and safety of the Allurion gastric balloon, this innovative technology is poised to become an increasingly popular option for individuals seeking a non-surgical approach to weight management.
Liraglutide: A Powerful Weight Loss Medication
What is liraglutide?
Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, a class of medications originally developed for the treatment of type 2 diabetes. GLP-1 is a naturally occurring hormone secreted by the intestines that plays a crucial role in regulating glucose metabolism and appetite [5]. Liraglutide, sold under the brand name Saxenda for weight management purposes, mimics the effects of GLP-1, offering a novel approach to treating obesity [4]. By interacting with GLP-1 receptors in the body, liraglutide exerts its potent weight-loss effects, making it a valuable tool in the fight against obesity.
Mechanism of action
Liraglutide’s weight loss properties can be attributed to its multifaceted mechanism of action. Firstly, liraglutide acts on the brain’s appetite control centres, specifically the hypothalamus, to reduce feelings of hunger and increase satiety [5]. By modulating the activity of neurons involved in appetite regulation, liraglutide helps individuals feel fuller for longer periods, reducing the desire to consume excessive calories [7]. Additionally, liraglutide slows down gastric emptying, prolonging the time food remains in the stomach, further contributing to increased feelings of fullness [5].
Moreover, liraglutide has been shown to influence energy metabolism. Studies have demonstrated that liraglutide treatment leads to increased energy expenditure, potentially by stimulating brown adipose tissue activity [5]. Brown adipose tissue is metabolically active and plays a role in thermogenesis, the process of heat generation in the body. By enhancing brown adipose tissue activity, liraglutide may contribute to increased calorie burning and weight loss [7].
Efficacy and safety of liraglutide in weight management
The efficacy of liraglutide in weight management has been extensively studied in clinical trials. The SCALE Obesity and Prediabetes trial, a randomized, double-blind, placebo-controlled study, evaluated the effects of liraglutide 3.0 mg in overweight and obese adults without diabetes [8]. Participants who received liraglutide achieved significant weight loss compared to those in the placebo group, with an average weight loss of 8.4 kg over 56 weeks [8]. Additionally, liraglutide treatment led to improvements in obesity-related comorbidities, such as dyslipidemia and hypertension [8].
The safety profile of liraglutide has been well-established through clinical studies. The most common side effects associated with liraglutide treatment include nausea, diarrhoea, and constipation, which are typically mild to moderate in severity and tend to subside over time [4]. Rare but serious side effects, such as pancreatitis and gallbladder disease, have been reported in a few patients [4]. However, the overall risk-benefit profile of liraglutide remains favourable, making it a valuable option for weight management in appropriate patients.
Liraglutide’s powerful weight loss effects, combined with its ability to improve obesity-related comorbidities, have solidified its position as a key player in the pharmacotherapy of obesity. As healthcare professionals continue to recognize the importance of a multifaceted approach to weight management, liraglutide has emerged as a potent tool in the arsenal against obesity.
The Synergistic Effect of Combining Allurion Gastric Balloon and Liraglutide
How the combination therapy works
The combination of the Allurion gastric balloon and liraglutide represents a novel, synergistic approach to weight management. By addressing both the physical and physiological aspects of hunger and satiety, this dual therapy offers a comprehensive solution for individuals struggling with obesity. The Allurion gastric balloon, as previously discussed, works by occupying space in the stomach, reducing its capacity and promoting a feeling of fullness [2]. This physical restriction helps patients to consume smaller portions and reduce their overall calorie intake.
Liraglutide, on the other hand, targets the physiological pathways involved in appetite regulation and energy metabolism [5]. By mimicking the effects of the natural GLP-1 hormone, liraglutide decreases hunger, increases satiety, and slows gastric emptying [7]. When combined with the Allurion gastric balloon, these effects are further amplified, creating a powerful synergy that enhances weight loss outcomes.
Potential benefits of the combined approach
The potential benefits of combining the Allurion gastric balloon with liraglutide are numerous. Firstly, dual therapy addresses the multifaceted nature of obesity, targeting both the physical and physiological aspects of the disease [9]. By reducing stomach capacity and simultaneously modulating appetite and energy metabolism, patients may experience greater weight loss compared to either treatment alone.
Moreover, the combination of the Allurion gastric balloon and liraglutide may lead to improved long-term weight loss maintenance. While the gastric balloon is a temporary measure, typically removed after several months, liraglutide can be continued for an extended period to help patients maintain their weight loss [9]. The appetite-suppressing effects of liraglutide may assist patients in adhering to a reduced-calorie diet and healthy lifestyle habits, even after the removal of the gastric balloon.
Additionally, the combination therapy may result in a more favourable side effect profile compared to other weight loss interventions. The Allurion gastric balloon is a non-surgical, reversible procedure, eliminating the risks associated with more invasive bariatric surgeries [2]. Liraglutide, while associated with some gastrointestinal side effects, has a well-established safety profile and is generally well-tolerated by patients [4].
Clinical evidence supporting the efficacy of the combination therapy
While the combination of the Allurion gastric balloon and liraglutide is a relatively new approach, early clinical evidence suggests promising results. A pilot study conducted by Trang et al. investigated the efficacy and safety of combining the Elipse gastric balloon with liraglutide in obese patients [9]. The study found that the combination therapy resulted in significant weight loss, with patients achieving a mean weight loss of 17.1% after 16 weeks [9]. Furthermore, the combination therapy led to improvements in obesity-related comorbidities, such as hypertension and dyslipidemia [9].
Although more extensive clinical trials are needed to fully establish the efficacy and long-term benefits of this combination therapy, the initial findings are encouraging. As research continues to explore the synergistic potential of the Allurion gastric balloon and liraglutide, this innovative approach may become an increasingly viable option for individuals seeking a comprehensive, non-surgical solution for weight management.
The combination of the Allurion gastric balloon and liraglutide represents a groundbreaking approach to weight management, harnessing the synergistic effects of physical space restriction and physiological appetite modulation. By addressing the complex nature of obesity through this dual therapy, healthcare professionals can offer patients a more effective, personalized solution for achieving and maintaining a healthy weight.
Patient Selection and Treatment Protocol
Criteria for selecting suitable candidates
Selecting the appropriate patients for the combination therapy of the Allurion gastric balloon and liraglutide is crucial for ensuring optimal outcomes and minimizing potential risks. Candidates for this treatment should have a body mass index (BMI) of 30 kg/m² or higher, which is the threshold for obesity [1]. In some cases, individuals with a BMI between 27 and 29.9 kg/m² may be considered if they have obesity-related comorbidities, such as type 2 diabetes, hypertension, or dyslipidemia [10].
Additionally, potential candidates should have attempted conventional weight loss methods, such as lifestyle modifications and pharmacotherapy, without success before considering the combination therapy [11]. It is essential to assess patients’ willingness and ability to adhere to the necessary dietary and lifestyle changes required for the treatment’s success.
Contraindications for the Allurion gastric balloon and liraglutide combination therapy include pregnancy, a history of pancreatitis, personal or family history of medullary thyroid carcinoma, or multiple endocrine neoplasia syndrome type 2 [4]. Patients with a history of eating disorders, severe gastrointestinal disorders, or previous bariatric surgery may not be suitable candidates and should be evaluated on a case-by-case basis [11].
Pre-treatment evaluation and preparation
Before initiating the combination therapy, patients should undergo a comprehensive medical evaluation to assess their suitability and identify any potential risks. This evaluation may include a detailed medical history, physical examination, laboratory tests, and imaging studies [11]. Patients should also receive counselling on the expected outcomes, potential side effects, and the importance of adherence to the treatment protocol.
In preparation for the Allurion gastric balloon insertion, patients may be advised to follow a liquid diet for a few days before the procedure to ensure a clear gastrointestinal tract [2]. They should also be informed about the necessary post-insertion dietary modifications, which typically involve a gradual transition from liquid to solid foods over several weeks [6].
Treatment duration and follow-up
The duration of the Allurion gastric balloon and liraglutide combination therapy may vary depending on individual patient needs and response to treatment. Typically, the Allurion gastric balloon remains in the stomach for approximately 16 weeks before it automatically deflates and is excreted naturally [3]. During this period, patients should receive regular monitoring and support from their healthcare team to ensure proper balloon placement, assess weight loss progress, and manage any potential side effects.
Liraglutide treatment can be initiated before, during, or after the Allurion gastric balloon insertion, depending on the patient’s specific needs and the healthcare provider’s recommendation [9]. The dose of liraglutide is usually gradually increased over several weeks to minimize gastrointestinal side effects [4]. Patients should be followed up regularly to monitor their response to liraglutide, assess weight loss progress, and adjust the dosage as needed.
After the Allurion gastric balloon is excreted, patients may continue liraglutide treatment for an extended period to support long-term weight loss maintenance [9]. Ongoing follow-up and support from the healthcare team are essential to reinforce healthy lifestyle habits, monitor for potential complications, and ensure sustained success in weight management.
By carefully selecting suitable candidates, providing thorough pre-treatment evaluation and preparation, and ensuring appropriate treatment duration and follow-up, healthcare providers can optimize the outcomes of the Allurion gastric balloon and liraglutide combination therapy, helping patients achieve and maintain a healthy weight.

While the Allurion gastric balloon and liraglutide combination therapy provides a powerful tool for weight loss, long-term success in weight management requires a commitment to lifestyle modifications. Dietary changes and increased physical activity play a crucial role in supporting the effects of the treatment and promoting overall health [12].
Patients should be encouraged to adopt a balanced, nutrient-dense diet that emphasizes whole foods, such as fruits, vegetables, lean proteins, and whole grains, while limiting processed and high-calorie foods [13]. Portion control is also essential, as the Allurion gastric balloon helps to reduce stomach capacity and promote satiety [2]. Patients should work closely with a registered dietitian to develop a personalized meal plan that aligns with their individual needs and preferences.
Regular physical activity is equally important for long-term weight management and overall health. Engaging in a combination of aerobic exercises and strength training can help patients maintain their weight loss, improve cardiovascular health, and increase muscle mass [14]. Patients should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week, along with two or more days of strength training exercises [14].
Behavioural therapy and support groups
Behavioural therapy and support groups are valuable components of a comprehensive weight management program. Cognitive-behavioural therapy (CBT) can help patients identify and modify unhealthy thought patterns and behaviours related to eating and weight [15]. By developing coping strategies, problem-solving skills, and stress management techniques, patients can better navigate the challenges of maintaining a healthy lifestyle.
Participating in support groups can provide patients with a sense of community, encouragement, and accountability. Sharing experiences, challenges, and successes with others who are on a similar journey can be incredibly motivating and empowering [16]. Support groups can be facilitated by healthcare professionals or peer-led, and may be conducted in-person or online.
Strategies for maintaining weight loss after treatment
Maintaining weight loss after the Allurion gastric balloon is expelled and liraglutide treatment is achieved requires ongoing dedication and effort. Patients should continue to adhere to the healthy dietary habits and physical activity routines established during treatment [12]. Regular follow-up appointments with healthcare providers can help patients stay on track, monitor progress, and address any concerns or challenges that arise.
Setting realistic goals, tracking progress, and celebrating achievements can help patients stay motivated and committed to their weight management journey [17]. Patients may benefit from using tools such as food diaries, fitness trackers, or mobile apps to monitor their daily habits and progress.
It is also essential for patients to develop a strong support system, including family, friends, and healthcare providers, who can offer encouragement and accountability [16]. Planning for potential setbacks and developing strategies to overcome them can help patients maintain their weight loss in the long term.
By prioritizing lifestyle modifications, engaging in behavioural therapy and support groups, and implementing strategies for long-term success, patients can optimize the benefits of the Allurion gastric balloon and liraglutide combination therapy and achieve sustainable weight management.
