Overview

About Gastric Balloon

A gastric balloon is a soft balloon placed in the stomach, usually through the mouth with a thin camera (endoscope), and then filled with saline. It takes up space, so you feel full sooner, and it is removed the same way after a set period, often about six months. Some types are swallowed as a capsule instead.

There is no surgery and no permanent change to the stomach. Weight loss is generally more modest than after bariatric surgery and depends heavily on changing eating habits while the balloon is in place, because weight is often regained after removal without those changes.

Suitability

Who it may be suitable for

  • A BMI above the healthy range, often 30 or more, where surgery is not recommended or not wanted
  • Wanting a temporary aid alongside a structured diet and activity programme
  • No previous stomach surgery, large hiatus hernia or stomach ulcer
  • Willingness to follow up with a dietitian for the whole period

These are general points only. Whether a procedure is suitable for you is decided by the treating surgeon and team after reviewing your medical history, tests and an in-person assessment, not from weight or BMI alone.

The process

How it works

  1. Medical review

    You share your height, weight, medical conditions, medication, previous operations and recent blood tests. The team decides whether an assessment is appropriate and what else is needed before you travel.

  2. Assessment in Istanbul

    You meet the surgeon and anaesthetist and have blood tests and other checks, often including an ultrasound or endoscopy. A dietitian explains the eating plan, and the procedure is confirmed only if it is still appropriate.

  3. Placement

    Under sedation, the balloon is passed into the stomach with an endoscope and filled with saline. It usually takes less than half an hour.

  4. Discharge and follow-up

    You leave with written diet and medication instructions. Follow-up with the clinic’s dietitian and regular blood tests continue remotely and with your own doctor at home.

Recovery

What recovery usually looks like

  1. Days 1–3

    Nausea, vomiting and stomach cramps are common while the stomach adjusts. You take the prescribed anti-sickness medicine and sip fluids to avoid dehydration.

  2. Weeks 1–3

    You move from liquids to soft foods and then a normal-textured diet in small portions.

  3. Months 1–6

    You follow a structured eating plan with dietitian support. The balloon is removed at the end of the set period.

  4. After removal

    Keeping up the habits learned during the balloon period is what helps maintain the weight loss.

Timelines vary between people. Always follow the aftercare instructions from your treating clinic.

Good to know

Risks and considerations

  • Nausea and vomiting in the first days can be severe enough to need early removal.
  • Rarely, the balloon deflates and moves into the intestine, causing a blockage that needs urgent treatment.
  • Stomach ulcers, inflammation of the pancreas and perforation of the stomach are rare but serious complications.
  • Sedation carries its own, usually small, risks.
  • Weight is commonly regained after removal if eating habits have not changed.
FAQ

Common questions

How much weight can I expect to lose?

Results vary. Weight loss is generally modest compared with surgery and depends on following the diet and activity plan during the months the balloon is in place.

Is the balloon permanent?

No. It is removed after a set period, often around six months, depending on the type used.

What happens if I feel very unwell after placement?

Contact the clinic straight away. Persistent vomiting, inability to keep fluids down or severe pain need prompt medical review, and the balloon can be removed early if needed.

How is the cost decided?

It depends on the procedure recommended after your assessment, the hospital stay and any additional tests. You receive a written, itemised quote before anything is booked, with no obligation to proceed.
