Dr. Marcus Fitzroy Lewis

Dr. Marcus Fitzroy Lewis is a consultant endocrinologist at Milton Cato Memorial Hospital in Kingstown, Saint Vincent and the Grenadines, specialising in diabetes mellitus, thyroid disease, and metabolic disorders. With 15 years of specialist experience and MRCP (UK) qualifications, he is one of the most highly trained endocrinologists in the Eastern Caribbean. The Caribbean region faces one of the world's highest burdens of type 2 diabetes and its complications, making Dr. Lewis's expertise critically important for the population of Saint Vincent and the Grenadines. He manages both common metabolic presentations and complex endocrine disorders referred from primary care across the island nation.

Dr. Lewis completed his MBBS at a recognised medical university and subsequently achieved the MRCP (UK) — the Membership of the Royal College of Physicians — through rigorous written and clinical examination. He completed subspecialty training in endocrinology and diabetes within the Caribbean and UK systems, gaining expertise in diabetes technology, thyroid ultrasound interpretation, and pituitary-adrenal axis assessment. His Endocrinology and Diabetes Subspecialty Training provided structured exposure to the full spectrum of endocrine disorders. He maintains CME through the Royal College of Physicians and the Caribbean endocrinology CME network.

Dr. Lewis manages the full spectrum of endocrine and metabolic conditions with particular depth in diabetes management. His diabetes practice encompasses Type 1, Type 2, and gestational diabetes, using structured approaches to glycaemic optimisation, insulin initiation and titration, and complication screening for retinopathy, nephropathy, and neuropathy. He manages diabetic ketoacidosis (DKA) and hyperosmolar hyperglycaemic state in the inpatient setting. His thyroid practice covers hypothyroidism, hyperthyroidism, thyroid nodule assessment, and post-thyroidectomy management. He also evaluates and manages adrenal disorders, osteoporosis, and metabolic syndrome within a comprehensive endocrine framework.

Milton Cato Memorial Hospital is the main hospital in Saint Vincent and the Grenadines, and Dr. Lewis is accessible to international visitors and expatriates requiring endocrine specialist assessment. The island's warm climate and outdoor lifestyle attract active expatriates who benefit from specialist metabolic care. He consults in English and can prepare medical reports for insurance and international referral purposes. For complex investigations not available locally, he coordinates referrals to specialist centres in Barbados, Trinidad, and North America. The airport in Kingstown connects to regional hubs supporting onward travel for patients requiring tertiary specialist input.

Dr. Lewis has been recognised by the Saint Vincent and the Grenadines Ministry of Health for his contributions to improving diabetes and endocrine care on the island. His MRCP (UK) qualification from the Royal College of Physicians reflects internationally assessed medical competence.
