    Background Information 
    Professional profile:

    Dr Mark Cohen provides a comprehensive and personally-tailored service for patients with endocrine and diabetic conditions.  Multi-disciplinary assessment is available for patients with obesity or diabetes, with access to an expert dietitian and diabetic specialist nurse for patients under his care.  Thyroid or parathyroid patients who require a surgical opinion benefit from Dr Cohen’s close collaboration with a very experienced thyroid surgical team.  Dr Cohen qualified in medicine from the University of Birmingham in 1994 with a 1st class honours degree in Physiology.

    After becoming a member of the Royal College of Physicians in 1998 he returned to London to become a Medical Research Council Clinical Research Fellow at Hammersmith Hospital under the supervision of Professor Steve Bloom. His original research on the role of the gut hormones PYY, oxyntomodulin and ghrelin in the regulation of food intake culmunated in a PhD in Physiology, awarded in 2005.  Obesity surgery is believed to act through alterations in the release of these appetite-regulating hormones. Dr Cohen was appointed Consultant in Endocrinology and Diabetes at Barnet Hospital in 2006 and continues to have a specialist interest in the clinical management of obesity.

    Personal profile:

    Dr Cohen is married (to a dietitian) and has two young children (aged 3 and 6 yrs).  He spent his childhood in Potters Bar and went to school in Elstree. Dr Cohen’s many interests include tennis, skiing, ice-skating, music and theatre, art-house films, modern art and design, 20th century furniture and technological gadgets!
