I am a Consultant Gastroenterologist with over two decades of experience, specialising in advanced endoscopic procedures and clinical nutrition. My practice focuses on the management of complex gastrointestinal and liver conditions.
I perform a wide range of diagnostic and therapeutic endoscopic procedures, including gastroscopy, colonoscopy, endoscopic ultrasound (EUS) and ERCP. My work includes advanced interventions such as dilation of oesophageal strictures, Botox treatment for achalasia, endoscopic resection of early gastrointestinal cancers and removal of complex gastric polyps, often requiring specialist equipment and multidisciplinary support.
I also manage a broad spectrum of gastrointestinal conditions, including dyspepsia, ulcers and reflux disease, Barrett’s oesophagus, irritable bowel syndrome and disorders of gut–brain interaction, as well as chronic abdominal pain, bloating, diarrhoea and constipation. My clinical practice also includes inflammatory bowel disease, gastrointestinal cancers, small bowel disorders such as SIBO and IMO, and complex nutritional conditions including malnutrition, malabsorption and obesity.
Over my career, I have performed in excess of 12,000 endoscopic procedures, including more than 5,000 gastroscopies, over 3,500 colonoscopies, more than 1,500 ERCP procedures and over 2,000 endoscopic ultrasound examinations with associated therapeutic interventions.
I qualified from Bangalore University in 2000 and completed 12 years of specialist training in the UK. I further developed my expertise through an Advanced Interventional Endoscopy Fellowship at the Royal Adelaide Hospital in Australia and advanced nutrition training at the Intestinal Failure Unit in Salford.
Since my appointment as a Consultant in 2012, I have been based at Royal Blackburn Hospital, where I contribute to advanced endoscopy services, upper gastrointestinal cancer care and nutritional management. I lead therapeutic endoscopy for the Lancashire and South Cumbria Cancer Network and have been recognised for contributions to clinical practice and education, including the ‘Extra Mile – Individual’ and ‘Best Trainer/Educator’ awards in 2025.
I am also involved in charitable activities and participate in events such as the Tour de Manc to support local health causes. In addition, I have an interest in integrative approaches to gastrointestinal health and have been involved in collaborative research exploring the combination of traditional and contemporary medical practices.
My clinical work includes gastroenterology, hepatology, therapeutic endoscopy, endoscopic ultrasound, ERCP and the management of biliary and pancreatic disorders, as well as bariatric and nutritional care.
