Alex is passionate about working with patients to control their weight, obesity and related diseases in order to live longer and healthier lives. He also has a special interest in medical and surgical education, and in particular challenging stigma and misinformation around obesity and its treatments.

Alex makes sure his patients have a full and realistic understanding of obesity surgery and what it can and cannot do – so that they can make their own decision, in their own time. We then work with patients to be as well prepared as possible for their operation, recover as quickly as possible and maximise the long-term benefits.
