What is a gastric balloon?
A temporary device occupies space in the stomach and supports fullness with smaller portions.
- It is not surgeryThe stomach is not cut or permanently reduced.
- The device alone is not enoughIt is used with nutrition, activity and follow-up support.
Who may be suitable?
Suitability depends on health and the selected device, not weight alone.
- Adults seeking a non-surgical optionIt may be assessed when nutrition and lifestyle measures have not produced sufficient results.
- Appropriate body mass indexBMI, associated conditions and weight history are assessed together. Some devices allow assessment from BMI 27.
- Readiness for nutrition changes and follow-upRegular reviews and willingness to maintain habits after the balloon are important.
Who should not have a balloon?
This treatment pathway is not performed or recommended in the following situations:
- Pregnancy and breastfeedingBalloon treatment is not performed during these periods.
- Active ulcer or bleedingIt is not performed with active gastric/duodenal ulcers or gastrointestinal bleeding.
- Previous gastric or oesophageal surgeryPeople with previous surgery in these areas are not considered suitable for this treatment pathway.
- Large hiatus herniaIt is not performed with a large hiatus hernia.
- Recent heart attackTreatment is not planned after a recent heart attack or with clinically unstable heart disease.
- Anticoagulants such as warfarinThis treatment pathway is not recommended while taking anticoagulants. Never stop prescribed medicine independently.
- Swallowing difficulty and obstruction riskSignificant swallowing problems, obstruction risk and other digestive diseases require assessment.
The full exclusion list must be checked against current device instructions. Never stop medicines without medical advice.
Types of gastric balloon
There are two main groups according to placement method:
Endoscopic gastric balloon
Placed using an endoscope under anaesthesia or sedation. Depending on the model, six- and twelve-month options are available. It is removed endoscopically at the end of treatment; some models are adjustable.
Swallowable gastric balloon
The capsule is swallowed, its stomach position confirmed by imaging and the balloon filled. Routine placement needs neither anaesthesia nor endoscopy. The balloon is designed to empty and pass naturally after about sixteen weeks.
Intolerance or complications with a swallowable balloon may still require endoscopic or surgical intervention.
Benefits and limitations
A balloon supports habit change.
- It does not permanently change stomach anatomy.
- It is temporary and requires regular follow-up.
- Nausea, cramps and vomiting can occur early on.
- It does not automatically resolve emotional eating or unhealthy habits.
How much weight might be lost?
Weight loss varies; targets depend on treatment duration and health.
- An individual 10–25% target rangeThis may be discussed according to starting weight, follow-up duration and the lifestyle programme. It is not the expected four-month average for one balloon or a promised result for everyone.
- Published average: approximately 10–15%Manufacturer data report this average total body-weight loss at about sixteen weeks.
- What affects the outcomeStarting weight, device, eating habits, activity, health conditions and follow-up all contribute.
No particular weight or percentage is guaranteed. Higher targets may require longer follow-up or additional treatment.
Nutrition and follow-up after placement
Early nutrition follows a stepwise plan according to tolerance.
- 1. Liquid stageStart with small, frequent sips. Preventing dehydration and meeting clinician-set protein needs are priorities.
- 2. Progressing to puréePurée begins during or after the first week according to tolerance and clinic protocol. Some protocols retain liquids only throughout the first week.
- 3. Soft food, then solidsTexture increases gradually. Do not skip stages or force solid food while vomiting or in pain.
- 4. Personalised nutritionThe clinician and dietitian adapt the plan to diabetes, kidney disease, reflux, medicines and daily routines.
Small, frequent intakes may be needed to meet fluid and protein needs early on. A two-meal schedule is not imposed during adaptation.
Possible symptoms and urgent warning signs
Nausea, vomiting, cramps and reflux can occur early on. Keep the team informed.
- If symptoms do not ease in the first 3–5 daysReport nausea, vomiting and cramps to the treating clinician and remain in contact with the team.
- Do not wait with these symptomsSeek immediate medical help for inability to keep fluids down, repeated vomiting, markedly reduced urine, dizziness or severe/worsening abdominal pain.
- Signs of bleedingBloody vomit or black stools require urgent assessment.
- Support after medical assessmentMedicine adjustment, intravenous fluids in a healthcare setting or early removal may be considered.
Rare but serious problems include obstruction, bleeding, ulcers, migration or perforation. Do not wait 3–5 days with severe symptoms.
Lifestyle and weight maintenance
Use the balloon period to develop habits that can continue after treatment, not only to lose weight.
- Small portions and slow eatingChew thoroughly and stop when comfortably full.
- Plan meal timesAfter initial liquid/purée adaptation, selected patients may consider two main meals and finishing dinner around 17:00–18:00. This schedule does not apply to everyone.
- Use a balanced Mediterranean-style patternInclude vegetables, pulses, fish and olive oil; personalise protein intake for your health.
- Reduce highly processed foodsReduce ultra-processed packaged foods, refined sugar, refined-flour foods, sweets and pastries.
- Maintain regular activityBuild suitable walking and muscle-preserving activity into everyday life.
- Continue follow-up afterwardsWeight can return if previous habits resume. Maintaining new habits and medical/dietetic follow-up supports weight maintenance.
The goal is broader than eating less: balanced nutrition, muscle preservation, activity and sustainable habits matter.
Frequently asked questions
Is balloon placement surgery?
No. Endoscopic balloons are placed and filled using an endoscope under anaesthesia or sedation. A swallowable balloon is taken as a capsule and filled after position confirmation. Routine swallowable placement needs neither anaesthesia nor endoscopy. Complications can require additional intervention.
Can weight return afterwards?
Weight can return if previous habits resume. Maintaining small portions, thorough chewing, suitable regular meals, balanced Mediterranean-style eating and activity supports weight maintenance. Follow-up should continue afterwards.
What if symptoms do not settle?
Report nausea, vomiting and cramps that do not ease within the first 3–5 days. Do not wait with inability to keep fluids down, persistent vomiting, severe pain or bleeding: seek immediate medical help.
