Orbera® is Proven to Help Patients Lose Up to 3.1x the Weight

With Orbera®, you learn portion control. The technology and design of the Orbera® balloon helps patients lose up to 3.1x2 the weight of diet and exercise alone. It is placed temporarily in your stomach for six months and can help patients lose 48% more3 than other FDA-approved gastric balloons.
For full safety information, download the Orbera Patient Information Booklet.

No Surgery

The gastric balloon is inserted orally through your esophagus and placed directly into your stomach during a quick, non-surgical procedure. There is no need for any incisions, stitches or scars.

Not Permanent

After the first six months of the weight loss program the stomach balloon is carefully removed and the aftercare program continues.

Proven Results

Orbera® is proven to help patients experience 3.1x more weight loss than diet & exercise alone and provide the right tools and resources to successfully learn to keep it off.

Before & After Photos

With Orbera®, you learn portion control and how to take control of your eating habits. See the results that real Orbera® patients have experienced!

How It Works

The entire non-surgical, outpatient procedure takes about 20 minutes.

First, a diagnostic endoscopy is done to ensure that it is safe to perform the procedure. Once you are mildly sedated and comfortable, the procedure can begin.

The deflated gastric balloon is inserted through the esophagus and into your stomach. A syringe is then used to fill the balloon, with a sterile saline solution, to about the size of a grapefruit.

For the next six months the Orbera® balloon is inside your stomach, reducing the amount you can eat, and re-training your brain to better anticipate when your stomach is getting full.

It’s during this time that open and constant communication with your support team is crucial to maximizing the benefits of Orbera®. This means regular face-to-face sessions with your treatment team, dietician, fitness trainer, psychologist and doctor.

During these first six months, with the stomach balloon and support team working in tandem, patients see the most drastic results – Losing 20 to 50 pounds (sometimes even more).

After you’ve had six months to change the way you eat and work with the support team to improve your nutrition, the balloon is removed. The simple and non-surgical procedure is very similar to the placement process, only taking 20 minutes.

For the remaining six months of the program, you’ll continue working closely with your Specialist to follow a personalized diet and exercise program.

At an additional cost, you can access Apollo Care, a tool that gives you convenient access to a virtual support team of nutritionists and dietitians via your phone or tablet.

Patients lose an average of 14% of total body weight at year one.¹

How It Works & What to Expect

ESG reduces the size of your stomach without incisions or scars using the FDA-authorized Apollo ESG™ System. This small suturing device attaches to a camera passed through your mouth into your stomach while you are asleep. A specially-trained doctor uses the Apollo ESG™ System to sew your stomach into a smaller shape, so you eat less and feel full faster. Watch the video to see how ESG and the Apollo ESG™ System work.

Following the ESG procedure, you’ll feel fuller when eating smaller portions and get a better understanding of just how much intake your body needs to lose weight. This helps to develop healthier eating habits moving forward, so you can enjoy sustained results.

After meeting with your doctor and nurses, you will be given medication to help you sleep and feel comfortable during the procedure.

Most patients typically can go home the same day. However, there may be some discomfort from the procedure. Do not drive or operate motorized vehicles or equipment the remainder of the day. Avoid alcoholic beverages. You may resume activity as soon as you are comfortable.

To help your stomach heal, you will be on a liquid diet for the first week or two, followed by pureed and soft foods for the next two weeks. Typically, by week four, you will be able to resume eating solid foods. Follow your doctor’s specific instructions.

With less room in your stomach, you should begin to feel full faster and lose weight. The procedure helps you to develop better eating habits and change your lifestyle for lasting results.

Clinical Evidence

Apollo ESG™ can help patients achieve lasting results. It’s an exciting option for those who have not experienced success with diet or exercise alone and are hesitant to pursue more invasive weight loss procedures.

Real Patients, Real Results

I recently underwent an Endoscopic Sleeve Gastroplasty (ESG) procedure at United Medical Doctors, and I must say that my experience was nothing short of outstanding. From start to finish, the entire process was smooth, efficient, and filled with care and professionalism. I attribute this remarkable journey to the exceptional Dr. Brian Lim, the state-of-the-art surgical center, and the commendable support staff. First and foremost, my doctor was truly exceptional. From the initial consultation to the follow-up appointments, they demonstrated an unparalleled level of expertise and genuine concern for my well-being. They patiently explained the ESG procedure, thoroughly discussed its potential benefits and risks, and answered all my queries, putting my mind at ease. Throughout the entire process, the doctor displayed remarkable empathy, which made me feel like I was in safe hands. Their commitment to patient care and focus on individual needs were beyond compare. The surgical center itself was top-notch, equipped with the latest medical ESG equipment. The modern facilities and strict adherence to hygiene and safety protocols gave me immense confidence in the procedure. The center's commitment to maintaining the highest standards in healthcare is commendable, and it undoubtedly contributed to my overall positive experience. After my procedure was done, I did not have any side effects and I was discharged after a few hours of my procedure. While Dr. Lim prescribed medicine for pain and nausea, I did not have any of those symptoms during the following days. I only had a couple of times where I felt pain but was minor and short-lived. My only real complication was with low blood pressure. I had to stop taking my blood pressure medication because it went a little too low. Another noteworthy aspect of my ESG journey was the exceptional support from the Fitness and Weight Loss Director and the Nutritionist. From day one, they both have been there for me and helped me to schedule my initial consultations and after procedure follow-ups. I know that the key to my weight loss journey now resides in my nutrition and wellness. I am glad to have the support of the staff at United Medical Fitness because the ESG procedure was just the beginning of my journey for a better and healthy me. In conclusion, my experience with the ESG procedure was exceptional due to the outstanding doctor, the superb surgical center, and the supportive staff. I am incredibly grateful for the care and attention I received throughout the entire process. If you are considering an ESG or any other medical procedure, I highly recommend this facility for its exemplary standards and commitment to patient satisfaction. I can confidently say that they have set the benchmark for medical care, and I couldn't have asked for a better experience.

Andrew wasn't happy with himself. Andrew would look in the mirror and wonder if the day would ever come where he would feel comfortable in his own skin. Andrew believes trying Orbera® was a changing point in his life. By his first follow-up appointment he had already lost his first 5 lbs - and that was just the start. By the end of the first 6-months of his Orbera® weight loss journey Andrew had lost 30 lbs. His eating habits had changed and he felt a constant sense of accomplishment. Years ago he would just eat and eat until he felt overly full, but with the Orbera® stomach balloon he realized that he had to change his eating habits. Between portion control and eating slowly, Andrew was able to change the way he ate. It has changed Andrew's life and he believes it can change yours too.

It was time to change. Mary was familiar with the Orbera® weight loss balloon. She liked that the procedure was non-surgical and only took about 15 minutes. So, she was beyond delighted when she discovered that a local clinic in Illinois offered the weight loss balloon. Thus, beginning her Orbera® weight loss journey. This weight loss procedure was exactly what Mary needed to help her lose the weight. She received support from a team of caring weight loss professionals from day one. Mary knew that she could communicate with her doctor and support team when she needed help or guidance. Mary has lost 92 lbs with the help of Orbera® weight loss balloon.

Lindsay is a stay-at-home mom who has a princess party business. She found Orbera® after significant weight gain. After seeing unflattering photos and videos of herself in her costume, she knew she needed a change. She felt completely out of control, and was mindlessly eating, especially at night. Lindsay needed help, but couldn’t do it alone. Lindsay tried everything she knew about. Every diet, pills, hypnotherapy. You name it – Lindsay did it. In her weight loss research, she stumbled upon the Orbera® gastric balloon. The last thing Lindsay tried, was the first thing that worked. With Orbera® she changed the way her brain works and the expectations she had of herself. Now for Lindsay, her relationship with food is second nature. Over a year later, Lindsay is living a whole new life, 54 lbs. lighter. She is doing more for herself because she feels better doing things. She goes out with her friends more. She goes out with her kids more. She goes shopping and its fun – instead of a tortuous thing to do.

Amanda, a registered nurse, says life before Orbera® was a little depressing, she was overweight, unhealthy and sad. She didn’t really want to be out in public, because when you don’t feel good, you don’t look good. Amanda exhausted every other option to lose weight. She tried pre-packaged foods, home delivered meals, all the medications she could think of, she had a personal trainer, and even had 3 gym memberships at one time — but nothing worked. Amanda wasn’t at a high enough weight to be considered for a surgical weight loss procedure so she started looking for weight loss physicians in my area – that’s when she heard about Orbera®. Amanda chose Orbera® because there was a decreased long term effect and less chance of complications because it wasn’t permanent. She liked the fact that Orbera® was a temporary measure while she learned new habits. As a nurse, she knew a lot of people gain back their weight after invasive surgeries because they never change the mental aspect of taking in food. After the balloon has been removed, Amanda is weightlifting and able to jog, something she never thought was possible. She is proud and amazed at what she has accomplished. A year and a half ago, Amanda was at rock bottom. It’s been over a year since Amanda had her balloon removed and she has kept off her 51 lb weight loss.

    Frequently Asked Questions

    How Much Weight Can I Lose With Orbera®?

    It is important for you to understand that the balloon is a tool to aid weight loss and must be used in conjunction with diet, exercise, and a behavior modification program. The amount of weight you lose and maintain will depend on how closely you follow your diet and adopt long-term lifestyle changes. The Orbera® clinical study has shown that weight loss varies from person to person. On average, patients lost 3.1x2 the weight of those that were on a diet and exercise program alone. In the US clinical study patients lost an average of 21.8 lbs.*

    What Happens If the Orbera® Balloon Leaks or Deflates in the Stomach?

    Orbera® has been reviewed in over 250 published global clinical papers, and a balloon deflation or leak is a very rare event. However, if the balloon should spontaneously deflate, you may no longer feel full after eating. If you suspect this may be the case, notify your Specialist immediately. A simple abdominal x-ray can determine whether either has occurred. If it has, your Specialist will arrange to remove the deflated balloon.

    Will I Gain the Weight Back After Removing the Orbera® Balloon?

    Published clinical studies4 of Orbera® have shown that, provided you keep to the prescribed diet and exercise regime, you will maintain weight loss through dieting post-removal. So, if you stick to your new, healthy lifestyle you will be well on the way to maintaining your weight loss.

    What is a Gastric Balloon?

    A gastric balloon is a non-surgical and short-term (temporary) weight loss device. A smooth, soft saline-filled balloon (about the size of an grapefruit) is placed in your stomach, allowing you to control your portion sizes by filling space in your stomach. By following professional health and wellness advice, you can adopt good healthy eating habits and change your lifestyle so you can lose weight quickly and keep it off long term.

    Are Gastric Balloons Safe?

    Gastric balloons have been used in the management of obesity for over 20 years. Over this time they have evolved in shape, size, and design resulting in a modern, durable product, which is now well established as a safe weight loss procedure. Nearly 300,0003 Orbera® balloons have been distributed worldwide.

    Do Gastric Balloons Help People Lose Weight?

    Once in place, the gastric balloon is filled with saline to partially fill the stomach so that they may consume smaller portions of food. Most weight is lost in the first three months, but because the gastric balloon stays in for six months, you will learn the right amount of food to eat to maintain your new weight long term.

    What Are the Possible Side Effects Associated With the Gastric Balloon?

    It is very likely that the presence of the balloon in the stomach will cause nausea or vomiting after placement. In some patients it may last one to two weeks. Your Specialist may prescribe medication to help minimize these potential effects. Patients will need to immediately contact their physician for any severe or unusual symptoms.

    Can the Balloon Injure My Stomach?

    The Orbera® balloon is constructed from a very smooth and soft silicone material to minimize the risk of irritating the stomach wall. You will also be prescribed medicines that will reduce the acidity in your stomach and help protect your stomach wall. Patients with prior stomach surgery are not eligible for the procedure because of a higher risk of the balloon causing a perforation in the stomach. Some patients without prior stomach surgery have also had stomach perforations but this is typically following extended periods of side effects. Patients should be advised to immediately contact their physician for any unusually severe, worsening, or recurrent symptoms lasting longer than two weeks.

    What is Body Mass Index (BMI)?

    The most widely used measurement for obesity. The BMI approximates body mass using a mathematical ratio of weight and height [(weight in kg ÷ height in meters) or (weight in pounds ÷ height in inches x 703)]. A BMI of 30 or more is regarded by most health agencies as the threshold for obesity. A BMI of 40 or more generally qualifies as morbid obesity. However, note that BMI measurements in body-builders and athletes may not be accurate determinants of obesity because the BMI does not distinguish between muscle and fat.

    Do You Qualify For Orbera®?

    To qualify for Orbera®, you must be an adult, have a Body Mass Index (BMI) of 30 to 40, and be willing to participate in a medically supervised program. Please schedule a complimentary consultation with our team to identify if you are a qualified candidate for Orbera®.

    How Does Orbera® Compare to the Alternatives?

    Orbera® vs Diet and Exercise Alone

    It’s been shown that the average person loses 3.1x more weight with Orbera® than with diet and exercise alone. Here’s some of the reasons why:

    • Diets can leave you feeling hungry or dissatisfied. Orbera® helps by taking up room in the stomach and encouraging portion control.
    • When you’re overweight, exercise can be challenging and uncomfortable. With Orbera® aiding your weight loss, physical activity can be more comfortable.

    Orbera® vs Other Gastric Balloons

    Over the past 20 years, Orbera® has become the #1 weight loss balloon in the world and is the only balloon recognized by the ASGE for its safety and effectiveness*. No other FDA-approved gastric balloon has shown more weight loss during their US clinical studies.

    How Does Orbera® Compare to Weight Loss Surgery?

    Orbera® vs Surgery

    Orbera® is a non-surgical weight loss procedure, which means no incisions, stitches, or scars. It takes about 20 minutes; most people go home the same day. And, importantly, the balloon is in place only temporarily, as opposed to permanent surgical alterations.

    * Orbera® has met the American Society for Gastrointestinal Endoscopy’s (ASGE) Preservation and Incorporation of Valuable Endoscopic Innovations (PIVI) threshold standards for the treatment of obesity.

    What Is Endoscopic Sleeve Gastroplasty (ESG) And How Does It Work?

    ESG is an endoscopic, incisionless procedure performed by a doctor who sutures the stomach with a specialized device called the Apollo ESG™ System. ESG reduces the stomach size by approximately 70%-80% using six to eight sutures. This limits the amount of food consumed and the number of calories absorbed by the stomach. It also prolongs the time food remains in the stomach, so you feel full longer.

    How Much Weight Can I Expect To Lose After ESG?

    According to a clinical study, patients lose an average of 14% of their body weight 12 months after undergoing the ESG procedure. Results will vary by person.

    Is The ESG Procedure Permanent?

    The sutures are made of durable, permanent material that does not dissolve. Over time, there will be scarring and bridging tissue to maintain the reduced stomach size and sleeve-like shape. In the event the sutures break, or the sleeve-like shape stretches, retightening can be performed.

    What Are The Most Common Side Effects of ESG?

    The most common side effects are gastrointestinal symptoms such as nausea, abdominal pain, vomiting, constipation, burping or diarrhea. These symptoms typically resolve within 30-60 days.

    All procedures have risk. Patients should talk with their doctor and understand all risks before having any procedure.

    Am I Eligible For The ESG Procedure?

    Apollo ESG™ is for adults with obesity and body mass index (BMI) between 30-50 kg/m2 who have not been able to lose weight or maintain weight loss through diet and exercise alone. Patients who are unable to have an upper endoscopy, are pregnant, are using certain types of blood-thinning medications or have malignant tissue, large hiatal hernia, potentially bleeding gastric lesions, or eating disorders, are not eligible for the procedure. Talk to your doctor about whether you are a candidate for ESG.
