I look after patients within all aspects of Diabetes and Endocrinology in both the inpatient and outpatient settings. As a Consultant at the Royal Free London Hospital I treat more than 1000 patients with Diabetes & Endocrine disorders in my outpatient clinics per year.

Endocrinology: I have set-up and lead the Specialist Thyroid clinic at the Royal Free Hospital. I also undertake regular General Endocrinology Clinics where I treat patients with parathyroid disorders, osteoporosis, calcium disorders, pituitary disease, adrenal disorders, obesity, polycystic ovarian syndrome, menstrual irregularities and menopausal symptoms, hypogonadism and symptoms of fatigue, sweating and flushing. I am a core member of the Thyroid, Parathyroid and Adrenal Royal Free London MDTs (Multidisciplinary Team Meetings). In addition to my role as the Clinical Lead for the Thyroid Services, I am the Clinical Lead for the overall Royal Free London Endocrine Outpatient Services transformation & redesign Programme.

Diabetes: My practice in Diabetes includes adult type 1 & type 2 outpatient Diabetes Clinics; and in the inpatient setting the management of Acute Diabetes emergencies, Diabetes and its complications in acutely unwell patients. Furthermore, I am one of the two Consultants who deliver Specialist antenatal clinic at the Royal Free for the management of Diabetes (type 1/type 2/gestational diabetes) and Endocrine disorders in pregnancy.


At the Royal Free Hospital, I regularly participate to the Acute Medical on calls looking after acutely unwell patients across a spectrum of systemic disorders and often of high acuity and disease complexity. In addition, I contribute to the delivery of the Acute Medical rota at the Princess Grace Hospital. My broad range of clinical experience and expertise enables me to consistently deliver holistic, patient-focused, evidence-based, high-quality, individualised clinical care. Moreover, my patients benefit from my close collaborations with professionals across all Medical & Surgical specialties.
