Dr Marcus Lyall

Consultant Physician


Specialises in

I have been consultant in diabetes, endocrinology and general internal medicine at the Royal Infirmary of Edinburgh since 2017. I was awarded a PhD in the effects of diabetes on the liver in 2016 from the University of Edinburgh.  I am a Fellow of the Royal College of Physicians of Edinburgh.

My current clinical practice encompasses a wide range of endocrine conditions including thyroid disorders, Addison’s disease (adrenal insufficiency), calcium disorders and pituitary disorders.  I also lead the regional endocrine thyroid nodular disease and thyroid cancer service.

My clinical practice also includes all aspects of type 1 and type 2 diabetes care and cardiovascular risk management.  I have a specific interest in the use of newer type 2 diabetes therapies, tailoring the approach to each patient to promote weight loss and reduce the risk of disease complications.
