Gastric balloon and gastric Botox in Türkiye: what UK patients ask before booking

Gastric balloons and so-called gastric Botox are heavily advertised to UK patients as a quick, non-surgical option in Türkiye: no scar, a short trip, home within days. This guide answers the practical questions people ask before booking one of these treatments in Antalya. It does not replace a medical consultation – whether either option suits you is a decision for a doctor after examining you.

Gastric balloon or gastric Botox – which one are people asking about?

They are very different treatments, and only one of them has solid evidence behind it.

	Gastric balloon	Gastric Botox
What it is	A soft balloon filled with fluid in the stomach, so you feel full sooner	Botulinum toxin injected into the stomach wall during an endoscopy
How it is placed	By endoscopy under sedation, or swallowed as a capsule	By endoscopy
Approved for weight loss?	Yes, as a medical device (several models)	No – not in the UK, EU or USA
Evidence	Randomised trials	Few small studies; no reliable effect compared with placebo
Main concern	Nausea and vomiting at first; rare stomach ulcer, perforation or bowel blockage	Botulism, with paralysis and breathing problems

The rest of this guide focuses mainly on the balloon. If you are considering gastric Botox, read the section on its safety first.

Is it done as an outpatient?

Usually, yes. An endoscopic balloon is placed through the mouth under sedation in a short procedure, and most patients go home or back to the hotel the same day. The swallowable balloon needs no endoscopy or sedation: you swallow a capsule, and it is filled with fluid through a thin tube. Before either, the clinic should assess you, and many carry out a gastroscopy first.

How many days do I need in Antalya?

Plan for more than the procedure day. Almost everyone feels unwell at first: in the Orbera approval study, around 87 per cent had nausea and around 76 per cent vomited, mostly mild to moderate and settling within two weeks. Cramping pain is typical in the first 48 hours, and nausea and vomiting over two to three days.

Day	What typically happens
Arrival	Transfer, consultation, blood tests, check of your medical history
Procedure day	Balloon placed; home or hotel the same day on a liquid diet with anti-sickness medicine
Next 2–3 days	The hardest phase: nausea, vomiting, cramps; small sips of fluid
Before flying	Follow-up check; written discharge letter and balloon card

Ask the clinic in writing how many nights it recommends, and whether you can extend if you cannot keep fluids down.

How much weight will I realistically lose?

Expect a moderate, temporary result rather than a transformation. In US approval studies, patients with a balloon and a diet programme lost on average:

• Orbera: 10.2 per cent of body weight after six months (3.3 per cent without the balloon)
• Spatz3: 15.0 per cent after 32 weeks (3.3 per cent without)
• Allurion (two balloons in sequence): 6.9 per cent after 48 weeks (3.1 per cent without)

For someone weighing 17 stone, 10 per cent is about 1 stone 10 lb. Everyone in these studies also followed a diet and exercise programme. The balloon only works while it is in place: in a Greek study of 500 patients, only 23 per cent of those followed up still had meaningful weight loss after five years. The US gastroenterology society AGA recommends the balloon only alongside a structured lifestyle programme.

When and where is the balloon removed – do I need to fly back?

This is the question to settle before you book. It depends on the type:

• Endoscopic balloons stay in for about six to twelve months, depending on the model, and must be removed by endoscopy. That means either a second trip to Türkiye or a private appointment with an endoscopy service in the UK.
• The swallowable balloon opens a valve after about four months, deflates and passes naturally. No return trip is needed for removal.

Do not assume an NHS hospital will remove a privately fitted balloon as a routine appointment. A balloon left in too long can leak and move into the bowel.

Tip: Get the removal date, the place and who pays for it in writing before you pay a deposit. If removal is planned in the UK, contact the UK provider before you travel.

Is it safe in Türkiye?

A gastric balloon is an approved device, but it is not risk-free anywhere. Depending on the study, around 9 to 19 per cent of balloons are removed early, mostly because they are not tolerated. Rare but serious complications include stomach ulcers and bleeding, perforation of the stomach wall, over-inflation, pancreatitis and bowel blockage from a deflated balloon. The US FDA reported 18 deaths worldwide with fluid-filled balloons between 2015 and 2020. In 2026 the UK regulator MHRA issued updated safety information on the Allurion balloon about blockages and perforation.

Safety in Antalya depends far more on the doctor, the assessment beforehand and the aftercare plan than on the country. You should not have a balloon if you have had previous stomach or weight-loss surgery, a large hiatus hernia, stomach ulcers, are pregnant or breastfeeding, or have an eating disorder – the full list is for the doctor to check.

Is gastric Botox safe?

The evidence does not support it. A randomised trial at the Mayo Clinic with 60 patients found no difference in weight compared with a salt-water injection, and a 2023 review concluded the treatment does not reliably lower weight or BMI.

In early 2023, at least 87 people developed botulism after gastric Botox at two private hospitals in Istanbul and Izmir, according to the ECDC. Cases were reported in Türkiye, Germany, Switzerland, Austria and France. The ECDC advised European citizens against this treatment in Türkiye, and NHS travel health services published the warning for UK travellers.

If you have had gastric Botox, watch for these signs in the following weeks:

• double or blurred vision, drooping eyelids
• difficulty swallowing or speaking, a changed voice
• increasing muscle weakness
• shortness of breath

Any of these is an emergency: call 999 and say you had Botox injected into your stomach. In the German and Austrian cases, symptoms began after about two days on average, but hospital treatment started only after about nine days.

How do I check the doctor and clinic?

Ask direct questions and expect clear answers in writing:

1. Who places the balloon, and how much endoscopy experience do they have?
2. Which balloon model is used, and how long does it stay in?
3. What tests are done beforehand – is a gastroscopy included?
4. What medicines will I get for nausea and stomach protection?
5. Who is my contact after I return home, and how do I reach them?
6. What happens if I cannot tolerate the balloon and it must come out early?
7. When and where is it removed, and is that included?
8. What diet programme comes with it, and for how long?

Be wary of weight promises (“lose 3 stone in three months”), Botox injections offered by beauty salons, no assessment before treatment, and pressure to pay a deposit quickly. More checks are in our guide to choosing a reputable clinic.

Do staff speak English?

Clinics in Antalya that treat international patients usually have English-speaking coordinators. What matters more is whether you can speak to the doctor directly – with a professional interpreter if needed – about risks and aftercare, and whether your consent form and discharge letter are in English.

What is usually in the package?

Packages vary, so compare the written details rather than the headline. Typical items to check:

• airport and hotel transfers, and the number of hotel nights
• consultation, blood tests and any gastroscopy beforehand
• the balloon and the procedure, plus medicines to take home
• follow-up check before you fly
• dietitian support after you return, and for how long
• removal of the balloon, or whether it is charged separately

Read the cancellation and refund terms too: see deposits, refunds and cancellation.

What if I feel ill back home – will the NHS help?

In an emergency, yes. Call 999 or go to A&E if you have severe or persistent stomach pain, constant vomiting, a swollen tummy, breathing difficulty, severe stomach and back pain, fever, blood in your vomit or black stools. If you cannot keep fluids down for hours, do not wait. For less urgent worries, call NHS 111 or speak to your GP, and contact your clinic.

Green urine or a sudden loss of fullness can mean the balloon is leaking: get it checked promptly. More in warning signs after surgery.

What documents should I bring home?

Document	Why it matters
Balloon or implant card	Shows model, fill volume, insertion date and planned removal date
Discharge letter in English	Tells your GP or A&E what was done
Procedure report	Includes findings from the endoscopy
Medication list	Anti-sickness and acid-reducing medicines, with doses
Clinic contact details	A named person and a number that works from the UK

Tip: Keep a photo of your balloon card on your phone, and tell your GP you have a balloon fitted.

Can I fly or go to the beach afterwards?

There is no wound, so the main limit is how you feel. Most people fly once the worst nausea has passed and they can drink normally; do not fly while vomiting or dehydrated. Antalya’s heat makes dehydration more likely, so stay in the shade and keep sipping fluids for the first days. More on travel planning in flying after surgery.
