Orbera 365 Gastric Balloon

The 12 Month Gastric Balloon

The 12 Month Gastric Balloon

The ORBERA365™ Managed Weight Loss System begins with a soft silicone intragastric (inside the stomach) balloon. The balloon is temporarily inserted into the stomach without surgery and will create the feeling of fullness after meals.

ORBERA365™ is a ‘tool’ that stays in your stomach for up to 12 months to help you lose weight and learn how to keep it off by understanding your new eating habits and being mindful about your calorific intake.

The Orbera 365 Procedure

The 12 month gastric balloon is inserted in a deflated state by an endoscopic (via the mouth) procedure. Once inside the stomach the balloon is immediately filled with sterile salt water through a small filling tube (catheter). The balloon has a self-sealing valve and once it is filled the catheter is gently removed. Once filled, the balloon will be too large to leave the stomach.

You’ll be lightly sedated whilst your clinician uses the endoscope to pass the deflated gastric balloon into your stomach.

The whole process normally takes around 20-30 minutes. You’ll rest in the clinic for 1-2 hours for observation before being discharged.


Placement Day

Wear comfortable clothes and shoes to your facility. Once the procedure is over you'll remain in the clinic for observation until the doctor dishcarges you - usually between 1-2 hours. Stick to cold liquids in small amounts beginning with a teaspoon, and increase the amount of liquids as you are able.

If you drink large amounts there's a higher risk of nausea and vomiting.

Week 1: Full Fluid Diet

The first few days might be uncomfortable as the stomach gets used to the presence of the balloon. You may experience further nausea, vomiting, bloating, diarrhoea and cramping until your body adjusts.

These conditions are typically experienced for the first few days and potentially up to about two weeks. Our dietitians will provide strict instructions for your hydration regimen during this period. In the days that follow it is critical that you drink plenty of water and avoid eating any solid foods.

Week 2: Pureed, Soft and Solid Foods

Your stomach is starting to adapt to the gastric balloon. So this is a time when it’s important to ‘listen’ to your body. The transition from PURÉE to SOLID foods should take approximately one week, but only progress when you can tolerate next stage foods comfortably. Always try to eat slowly, chewing food very well.

Day 1-2

In order to allow your stomach to adjust to the balloon, stick to cold fluids ie water, juice and broth, for the first day or two

Days 3-7

Once simpe fluids are tolerated well, you can begin to introduce different fluids such as protein shakes, yoghurt drinks, skimmed milk and weak coffee or tea (preferably decaffeinated)

Week 2

During the first 2-3 days in week 2 we would expect you to be on semi-liquid food (Purees) and be incorporating soft solids towards the second half of week 2.

3+ Weeks

By the time week 3 comes around, we can expect you to have started introducing solid foods into your diet, introducing them one at a time, eating slowly and chewing your food very well.

The Next 6 Months

After the first two weeks, your body will have adjusted to your Orbera balloon and you should be following a regular nutrition plan. Your success will now depend on how committed you are to adopting the principles of good health into your daily life.

Our dietitian will guide you on your nutrition regimen with calorie restrictions. using the app we provide you with. Remember, the Orbera balloon is only a ‘training tool’, like stabilisers on a bicycle. The Orbera System gives you a window of opportunity to adapt to the lifestyle changes you must make in order to maintain your ideal body weight.


At twelve months (or perhaps even earlier), the balloon will be removed. It’s a 20-30 minute procedure, very similar to the one you experienced for placement. The balloon will be punctured and the sterile water sucked up through a catheter. Once deflated the balloon will be retrieved and removed.
Following removal of the Orbera 12 month gastric balloon, very few people experience any side effects, but your doctor will keep you in the clinic for a couple of hours following removal so that any sedative effects have a chance to wear off.

Am I Suitable?

The Orbera 365 Gastric Balloon System is a tool to help you take control of your weight and give you the kick-start to a healthier lifestyle. Studies show that patients who have undergone the Orbera System procedure are more likely to maintain their weight loss over a longer period of time than compared to diets alone. In addition, there are certain medical reasons for which you may not be eligible for treatment with the Orbera. These may include:

Frequently Asked Questions

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.

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. Over 277,000 ORBERA® balloons have been placed worldwide.

  • Average weight loss is bertween 10-17% of your body weight. 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 and BiB® clinical study has shown that weight loss varies from person to person. On average, patients lost 3.1x 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.*

Orbera has been used in over 277,000 cases and reviewed in over 230 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.

Published clinical studies 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.

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.

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 doctor may prescribe medication to help minimize these potential effects. Patients will need to immediately contact their physician for any severe or unusual symptoms.

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.
