Nutrition is a fundamental piece of everyday life, as without it, we fail to function. My passion is to support, motivate and educate clients to enable self-empowerment, successful behavioural changes, and ultimately optimal lifestyle adaptations. We are too often faced with a media minefield of mixed dietary messages, meaning it can be hard to understand what dietary advice to follow. My aim is to provide uncomplicated and evidence-based advice, which is adapted to meet client specific goals.

So warm and welcoming. Excellent communication skills and explanation of my situation.
He was wonderfully reassuring and helpful to someone who was clearly both naive and apprehensive! He explained all the possible causes and cures for my problem and I came away knowing I was in the safest hands
as expressed in the 5 categories above -my experience has been only so very positive -- from my first contact through to my post op meeting with Professor Sanjay yesterday --- the process has been seamless -- as a patient i was always respected
i write to share that my hernia surgery with professor Purkayastha was truly excellent in every way ---- his team organized every detail of the process perfectly -- the actual surgery went exactly as he shared --- i always felt very relaxed that i was in top hands --a star
Excellent care from start to finish. Mr Purkayastha was very professional, kind and thorough with his care.
I am really grateful to Professor Sanjay Purkayastha for explaining in detail about my health condition and solution. I recommend him to everyone.
I have known Mr Purkayastha for 6 years now when he performed my gastric bypass. He is my first port of call for any abdominal issues I might encounter even though they have nothing to do with my bypass. He is caring, thorough, and makes me feel safe.
