Gastric Balloon Woes: Serious Complications Emerge
15 Apr
Summary
- Gastric balloons can cause serious complications like obstruction and perforation.
- Allurion reports multiple cases requiring intervention, including surgery.
- A patient described a terrifying experience of the balloon becoming lodged.
Individuals undergoing gastric balloon weight-loss procedures have been alerted to potential serious complications. The treatment, which involves swallowing a water-filled capsule to promote fullness, has seen a surge in popularity. While the balloon is designed to pass naturally after approximately four months, there have been reports of it becoming lodged, leading to significant health issues.
Allurion, a provider of gastric balloons to the NHS, has warned physicians of "known but serious complications." These include gastric outlet obstruction, small bowel obstruction, and gastric perforation. Between 2018 and 2024, eight cases of gastric perforation and small bowel obstruction, along with 13 cases of gastric outlet obstruction, were reported in Britain. All affected patients required further medical intervention, such as surgery or endoscopic procedures, but recovered without further complications.
Gastric outlet obstruction occurs when the passage between the stomach and small intestine is blocked, causing symptoms like nausea and vomiting. Small bowel obstruction is a medical emergency, and gastric perforation involves a hole in the gastrointestinal tract, potentially leading to severe internal bleeding and sepsis.
Somerset NHS Foundation Trust is currently the sole NHS trust offering gastric balloons, using them for patients with severe obesity (BMIs of 50-60) to manage related health conditions. However, numerous private clinics offer the procedure, with costs around £5,000 in the UK, and many Britons travel abroad for cheaper alternatives, such as in Turkey for approximately £1,900.
One patient, Alaina Shaw, recounted her distressing experience after paying £4,500 for the balloon, which became stuck in her intestines, causing immense pain and a hospital stay in intensive care. She expressed her desire to warn others about the procedure's dangers. Despite general safety assessments by the NHS, the long-term effects of this relatively new treatment are still under evaluation.
