At St Ellen’s Hospital, we’re proud to work with Professor Kamal Mahawar, one of the UK’s most respected bariatric (weight loss) surgeons.

For over a decade, Professor Mahawar has been helping patients transform their health and quality of life through safe, effective weight loss surgery. He has performed thousands of procedures, with results and safety outcomes consistently ranked among the top 10% in the country.

Professor Mahawar offers the full range of modern bariatric procedures, including:

• Gastric Sleeve
• Gastric Bypass (Roux-en-Y and Mini)
• Revisional Bariatric Surgery for patients who’ve had surgery before but need further help

His focus is always on tailoring the right procedure for you, ensuring it’s safe, effective, and backed by the latest evidence.

Trusted Expertise, Here and Around the World

Professor Mahawar is not only a highly experienced surgeon in the UK, but also a recognised leader internationally. He has:

• Published over 175 research papers and textbook chapters
• Delivered invited talks at conferences across Europe, the USA, Asia, and the Middle East
• Held senior roles in leading surgical organisations, including Chair of the National Bariatric Surgery Registry and Treasurer of the British Obesity & Metabolic Surgery Society

His research and leadership work means the techniques and safety standards you benefit from are the very same ones he’s helping to shape at a national and global level.

A Surgeon Who Understands the Journey

Originally from Kolkata, India, Professor Mahawar graduated top of his medical school and later moved to the UK, completing advanced surgical training and a master’s degree with distinction.

He understands that choosing weight loss surgery is a deeply personal decision—and one that can feel overwhelming. Patients describe him as approachable, reassuring, and thorough, always taking the time to explain every step so you feel confident and supported.

Outside the Operating Theatre

Away from work, Professor Mahawar enjoys family life in Newcastle upon Tyne with his wife, a software engineer, and their son, who’s now at university. He’s passionate about education, reading, and sharing knowledge to help others succeed—whether that’s the next generation of surgeons or the patients he cares for today.
