Gastric Balloon Explained: Costs, Benefits, and What to Expect in the UK

Man with Gastric Pain

Losing weight can be challenging, and for many, traditional diet and exercise alone may not be enough. A gastric balloon offers a non-surgical, medically supervised weight loss solution designed to help individuals shed excess weight safely and effectively. This temporary device is placed in the stomach to create a feeling of fullness, making it easier to reduce portion sizes and adopt healthier eating habits.

At The Gut Clinic UK, we specialise in providing expert-led gastric balloon procedures, ensuring patients receive the highest standard of care. With a team of experienced professionals and state-of-the-art facilities, we support individuals on their weight loss journey from consultation to aftercare. Our services are conveniently available across Bath, Birmingham, Manchester, London, Northampton, and Leeds, making expert weight loss support accessible throughout the UK.

What Is a Gastric Balloon?

Procedure Overview

A gastric balloon is a non-surgical weight loss device designed to help individuals control their appetite and eat smaller portions. The balloon is inserted into the stomach and filled with a saline solution or gas, creating a sense of fullness that reduces hunger and calorie intake.

There are two main types of gastric balloons:

  • Swallowable gastric balloons, such as the Allurion gastric balloon, do not require an endoscopy or sedation. Patients swallow a capsule attached to a thin tube, which is then inflated once inside the stomach.
  • Traditional gastric balloons are inserted via an endoscopic procedure and removed in a similar manner after 6 to 12 months.

Both options provide a temporary but effective tool for weight loss, particularly when combined with medical supervision and lifestyle changes.

Who Is Eligible?

A gastric balloon may be suitable for individuals who struggle with weight loss but do not qualify for invasive bariatric surgery. In the UK, eligibility typically includes:

  • A BMI between 27 and 40 (or higher in some cases).
  • No history of stomach or oesophageal disorders that could interfere with the procedure.
  • Commitment to a supervised weight loss programme, including dietary and lifestyle changes.

At The Gut Clinic UK, our specialists assess each patient’s health, weight loss goals, and medical history to determine suitability, ensuring the safest and most effective approach.

How Much Does a Gastric Balloon Cost in the UK?

The cost of a gastric balloon in the UK typically ranges from £3,000 to £5,000, depending on the provider, balloon type, and aftercare support. Swallowable gastric balloons, such as the Allurion gastric balloon, may be slightly more expensive due to their convenience and non-invasive nature, while traditional gastric balloons can vary in price based on procedure duration and clinical expertise.

Compared to bariatric surgeries like gastric bypass or sleeve gastrectomy, which can exceed £10,000, a gastric balloon offers a more affordable, reversible weight loss solution without the risks of surgery. When combined with a structured medical support plan, it can be a cost-effective way to achieve significant weight loss. At The Gut Clinic UK, we provide competitive pricing for gastric balloon treatments, ensuring expert care, tailored nutritional guidance, and post-procedure support.

Benefits of a Gastric Balloon

A gastric balloon is an effective, non-surgical weight loss solution that can help individuals achieve significant results without the need for invasive procedures.

  • On average, patients can expect to lose 10–15% of their total body weight within six months, with some individuals shedding up to 15–20kg, depending on adherence to dietary and lifestyle recommendations.
  • Unlike bariatric surgery, a gastric balloon is minimally invasive, requiring no incisions, stitches, or permanent changes to the digestive system.
  • The procedure is quick, with most patients resuming normal activities within a day, making it a convenient option for those with busy lifestyles.
  • Beyond weight loss, a gastric balloon can improve gut health, helping regulate digestion, reduce acid reflux, and promote healthier eating habits.

At The Gut Clinic UK, we provide expert guidance to maximise these benefits, supporting patients at every stage of their weight loss journey.

Side Effects and Risks

Short-Term Side Effects

Many patients experience temporary discomfort as the body adjusts, including:

  • Nausea and vomiting in the first 48–72 hours.
  • Abdominal discomfort or cramping, typically subsiding within a week.
  • Acid reflux or heartburn, which can be managed with prescribed antacids.

These symptoms usually improve within 7–10 days, and medical support is available to ease the transition.

Long-Term Considerations

While gastric balloons are generally safe, there are some long-term side effects of gastric balloon treatment, including:

  • Balloon deflation or leakage, which may require early removal.
  • Gastric ulcers or irritation if dietary recommendations are not followed.
  • Persistent acid reflux, which may need medication or removal.

At The Gut Clinic UK, we provide thorough pre-assessments and post-procedure care to minimise risks.

How Long Does a Gastric Balloon Last?

A gastric balloon remains in the stomach for 6 to 12 months, depending on the type used. Some 12-month gastric balloon models offer a longer-lasting solution.

To maintain weight loss after removal, patients should:

  • Follow a balanced, portion-controlled diet.
  • Engage in regular physical activity.
  • Continue nutritional and lifestyle coaching.

At The Gut Clinic UK, we offer comprehensive post-treatment support to help sustain long-term weight loss goals.
