You understand. You choose. We navigate together.
Your health is personal. Your treatment should be too.
The first step is understanding what is happening in your body — clearly, without unnecessary medical jargon. Once you understand the condition, the different ways forward become easier to see.
And there is rarely just one way forward. Medical decisions are often shades of grey rather than black and white. Guidelines and textbooks are valuable maps, but they cannot know your priorities, your lifestyle, your concerns, or what matters most to you.
That is why you remain at the centre of every decision.
My role is to help you understand the options: what each treatment might achieve, its limitations, its possible risks, and the practical realities of living with it. Rather than simply being told what to do, you should have the information you need to weigh those choices for yourself.
You then choose the path that makes the most sense for you.
Sometimes your choice may be different from what a textbook might suggest. That does not automatically make it the wrong choice. When you understand the benefits, risks and alternatives, your own values and circumstances matter enormously.
The doctor's role is not to take that decision away from you, but to help you make it well — and then help you move safely towards the health goals that matter to you.
Understand the condition. Explore the shades of grey. Choose your path. Move forward safely.
Consultant in Endocrinology
Expertise in Endocrine Care
Dr Kasi Subbiah, MBBS, MRCP (UK), FRCP, SCE, is a Consultant Endocrinologist providing private adult endocrinology care through Endocrine Consult. UK-wide video consultations are available, with suitable face-to-face appointments in Belfast.
He holds the Specialty Certificate in Endocrinology and Diabetes and CCT in Diabetes and Endocrinology and General Internal Medicine. He is a Consultant at the Royal Victoria Hospital, Belfast Health and Social Care Trust, with consultant-level experience across some of the UK's leading NHS trusts, including tertiary training at King's College Hospital, London. The focus is simple: get to the right diagnosis and the right plan fast, so patients aren't left waiting months for answers or watching a manageable condition drift.
His practice covers the full range of endocrine and metabolic disease — weight and metabolic health (including GLP-1 and tirzepatide therapy), hypogonadism and testosterone therapy, thyroid and adrenal disorders, pituitary and neuroendocrine conditions, calcium, parathyroid and bone conditions (osteoporosis and metabolic bone disease), women’s and men’s hormonal health, complex diabetes, insulin pump and hybrid closed-loop technology. Thyroid disease during pregnancy, suitable thyroid-cancer follow-up and clinically indicated imaging are also within the clinic’s scope. Within the NHS, Dr Subbiah has built and run rapid-access advice and triage services specifically to cut delays and get patients to the right care sooner — that same approach drives his private practice.
Every patient leaves the first consultation with a clear diagnosis and a concrete next step — no unnecessary appointments, no drift. Dr Subbiah works closely with other specialists where needed, so care moves forward instead of stalling in referral queues. The aim is straightforward: sort out the problem, get you feeling better, and do it quickly.
