Gastric balloon in Egypt: endoscopic or swallowable, risks and results

An intragastric balloon is a soft balloon, usually filled with saline, that takes up space in the stomach and limits how much you can eat (NIDDK). It is not surgery: nothing is cut, stapled or rerouted, and it does not permanently change the stomach or intestine (NIDDK).

The balloon is one part of a structured programme that also includes long-term changes to diet and lifestyle (Cleveland Clinic). The weight loss it brings is smaller than after weight-loss surgery (NIDDK), and what you learn about eating during those months largely decides what happens after it is gone.

Endoscopic balloon

The most common type is placed with an endoscope, a thin camera passed through the mouth, while you are under mild sedation; the procedure takes 20 to 30 minutes and the balloon stays for six months (Cleveland Clinic). A second endoscopy removes it, and a newer type can be left for up to 12 months (NIDDK).

Swallowable balloon capsule

With a swallowable balloon, you swallow the empty balloon and it is filled with salt water through an attached thin tube once it reaches the stomach, which usually takes around 20 minutes (NHS). One self-emptying type opens after about four months and passes out with the stool; in an Italian study of 38 patients, 37 balloons passed naturally and one was removed by endoscopy (Genco 2018). Not every swallowed balloon empties itself, and some still need endoscopic removal (Cleveland Clinic).

Balloons are intended for adults with a BMI of 30 to 40 (Cleveland Clinic). People with a higher BMI who qualify for surgery sometimes choose a balloon instead, or use it as a bridge to a later operation (Cleveland Clinic). Check your number with our BMI calculator.

A balloon is usually not suitable if you have a stomach ulcer, a hiatal hernia, a bleeding or clotting disorder, liver disease, a drug or alcohol problem, or previous surgery on the stomach or intestine (Cleveland Clinic).

1. An assessment and health screening confirm that a balloon is safe for you (Cleveland Clinic).
2. For the endoscopic type, you receive a mild sedative and the doctor looks inside the stomach with the endoscope to check for problems such as an ulcer (Cleveland Clinic, NHS).
3. The empty balloon is guided into the stomach, by endoscope or by swallowing, and filled with saline.
4. You rest for a few hours, then go home the same day (Cleveland Clinic).
5. At the end of the treatment period the balloon is removed by endoscopy, or passes naturally if it is a self-emptying type (Cleveland Clinic, Genco 2018).

Throughout the months with the balloon, regular contact with the dietitian matters as much as the device itself.

Preparation is lighter than for surgery, but it is not nothing. The team reviews your medical history, medicines and any previous abdominal operations, and may ask for blood tests before the procedure.

You will be asked not to eat or drink for some hours beforehand, as with any endoscopy, and to arrange for someone to take you home if you have sedation.

Early side effects are common: abdominal pain, sore throat, nausea, indigestion, acid reflux and constipation, which usually last about a week but sometimes longer (Cleveland Clinic).

Food returns in stages: liquids first, then puréed foods, then a soft diet, and finally the long-term eating plan set by your dietitian (Cleveland Clinic). Most of the weight loss happens in the first three months (Cleveland Clinic), so use them to build the habits you will keep after the balloon is gone.

Serious problems are uncommon, but you should know them (Cleveland Clinic):

• Persistent symptoms: fewer than 3% of people have symptoms beyond the first week that medicine does not relieve, and they need an endoscopy to adjust or remove the balloon (Cleveland Clinic).
• Spontaneous over-inflation, in a little over 2% of people (Cleveland Clinic).
• Deflation or movement of the balloon, in about 1.5% (Cleveland Clinic).
• Acute pancreatitis, reported to the US FDA and sometimes needing early removal (FDA).
• Perforation of the stomach or bowel, in about 0.1% (Cleveland Clinic).

The FDA warns that over-inflation can cause intense abdominal pain, a swollen abdomen, difficulty breathing or vomiting, and that pancreatitis causes severe pain in the abdomen and back (FDA). If you notice any of these, go to the nearest emergency department and call the team.

Call the team the same day if you have repeated vomiting, cannot keep fluids down, have a high temperature, or have tummy pain or difficulty swallowing that is getting worse (NHS). Vomiting blood, or vomit that looks like coffee grounds, is an emergency (NHS).

Average weight loss is about 10% of total body weight, or roughly 30% of excess weight (Cleveland Clinic). One study reported by Cleveland Clinic found an average loss of 10.2% of body weight (Cleveland Clinic), and in the Italian swallowable-balloon study the mean loss was 12.7 kg at 16 weeks (Genco 2018).

The hard part is keeping it off: only a minority of people maintain the loss over five years (Cleveland Clinic). A balloon is most useful when its months are used to change eating habits for good, or as a step towards surgery.

A balloon suits people who want a temporary, non-surgical start, or who are not yet ready or suitable for an operation. The gastric sleeve brings more weight loss but is permanent (Cleveland Clinic, NIDDK).

The price depends on the type of balloon, whether it needs one endoscopy or two (placement and removal), sedation and the hospital or endoscopy unit, tests beforehand, and how many dietitian and follow-up visits are included. Ask for a written, itemised quote; our page on gastric sleeve cost explains what a good quote should list, and the same questions apply here.
