Dr Rehan Haidry, Consultant Gastroenterologist and Interventional Endoscopist at Cleveland Clinic London, has been featured in the Daily Mail for his pioneering role in a new clinical trial that could transform how type 2 diabetes is treated.
The article, published on 9 September 2025, highlights a novel endoscopic procedure that uses radio-frequency vapour ablation (RFVA) to resurface the duodenum — the first part of the small intestine — with the goal of restoring insulin sensitivity and reducing reliance on medication.
The treatment, which is currently being trialled globally, has already shown remarkable early results. In one study, 100% of patients were able to stop insulin injections within nine months, with sustained improvements in blood sugar control. Dr Haidry is playing a pivotal role in the research study, performing the endoscopic procedures.
A New Frontier in Metabolic Care
The RFVA procedure targets the duodenal mucosa, which in patients with type 2 diabetes often becomes thickened and less responsive to insulin. This dysfunction contributes to poor glucose regulation and increased insulin resistance. By gently ablating the surface of the duodenum with controlled bursts of steam, the procedure triggers regeneration — allowing the gut to respond more effectively to insulin and helping to normalise blood sugar levels.
This approach builds on decades of research showing that gastric bypass surgery can rapidly improve diabetes symptoms, often before significant weight loss occurs but unlike bariatric surgery, RFVA is minimally invasive, performed as a day-case endoscopy under sedation.
“We’re mimicking the metabolic benefits of bypass surgery without the risks or recovery time,” says Dr Haidry. “It’s a powerful example of how endoscopy can be used not just for diagnosis, but for transformative therapy. With RFVA, we’re able to treat the root cause of insulin resistance in a way that’s safe, scalable, and patient-friendly. The early data is extremely promising.”
