Dr. Eoin O Sullivan

Consultant Endocrinologist


Dr. Eoin O’Sullivan was appointed in 2011 as Consultant Endocrinologist at the Bon Secours Hospital, Cork and senior clinical lecturer in University College Cork (UCC). A graduate of UCC, he completed his general professional training in Cork. His speciality training in Dublin and Galway was followed by a clinical fellowship in Dundee, Scotland. He completed his MD thesis in vascular calcification in type 2 diabetes. 

His main interest is in all forms of diabetes, especially those in whom attainment of glycaemic, lipid and blood pressure goals are difficult to achieve, secondary causes of diabetes and in-patient hyperglycaemia. He also has an interest in thyroid disorders, hypercalcaemia and disorders of sodium metabolism.

The Diabetes team has a specialist interest in type 1 diabetes in all individuals above 16 years of age.  Technological advances in the management of type 1 diabetes involving glucose sensors and subcutaneous insulin pumps are transforming how we manage this condition.  With full access to these technologies (subject to standard HSE approval) we support suitable patients with type 1 diabetes using them to optimise their glycaemic control and minimise hypoglycaemia. This team is led by Dr Eoin O'Sullivan and consists of Diabetes Nurse Specialists, Diabetes Dieticians, Podiatrist, Consultant Ophthalmologist and cardiovascular and vascular surgery support as required. In addition our Laboratory here provides assessment for all the tests necessary for monitoring of Diabetes.

A key aspect of our philosophy here in the Diabetes Unit in the Bon Secours Hospital Cork is the importance of the patient empowerment. We feel it is vital that individuals with diabetes have a full understanding of their condition and medications. Advantages to the service provided by our Diabetes Unit include ease of access to relevent knowledgeable diabetes healthcare professionals, consistency of approach whereby patients are "known" within the Unit (thereby reducing unnecessary repetition of information) and a truly patient centred approach which maximises the individuals ability to achieve the optimal level of diabetes control.
