I am a Consultant Endocrinologist and Diabetologist with over 10 years’ experience at consultant level, specialising in hormonal conditions, diabetes and metabolic health.
I support patients with a wide range of endocrine disorders, including diabetes (Type 1 and Type 2), thyroid conditions, polycystic ovary syndrome (PCOS), adrenal and pituitary disorders, and calcium and parathyroid conditions. I also have a particular interest in obesity management and male hormonal health, including low testosterone and related symptoms.
In addition, I help patients with common concerns such as fatigue, cholesterol and blood pressure management, and vitamin deficiencies. I offer treatments including insulin pump therapy and personalised plans to support long-term condition management.
My approach is focused on understanding each patient’s individual needs and providing clear, practical advice to help them manage their condition effectively. I aim to support patients in improving their overall health and wellbeing through a combination of medical treatment and lifestyle guidance.
Alongside my specialist work, I also practise general medicine, allowing me to take a holistic approach to patient care.
