About
Marjan Sadat Segahyat is a DHA-registered internal medicine specialist and endocrinologist at Biongevity, with more than 25 years across clinical practice, teaching, and research. She trained in medicine and internal medicine in Iran, completed a clinical endocrinology fellowship at the National University of Malaysia, and later led UCSI University's School of Healthy Aging, Medical Aesthetics and Regenerative Medicine. In Dubai, she is especially relevant for patients whose longevity plan runs through glucose, thyroid, hormone, weight, metabolic syndrome, or endocrine risk.
What to Know
Signature approach
Segahyat reads endocrine and metabolic signals together. Diabetes, thyroid disease, hormone imbalance, abdominal obesity, lipid patterns, and metabolic syndrome are not treated as isolated complaints; they become one longitudinal picture. Her visits are a natural fit when a patient needs lab interpretation, medication planning, regenerative or metabolic-health context, and a clinician who can keep chronic risk from fragmenting across specialties.
What sets them apart
- Healthy-aging department leadership. She previously headed UCSI University's School of Healthy Aging, Medical Aesthetics and Regenerative Medicine, giving her a direct academic bridge into longevity care.
- Endocrinology depth. Internal medicine training plus a Malaysian clinical endocrinology fellowship give her clear metabolic depth inside the Biongevity team.
- Active research profile. A biongevity.com-verified Google Scholar record covers endocrinology, internal medicine, environmental health, and healthy-aging topics.
Before You Book
- Clinical emphasis. Diabetes, thyroid, hormone, insulin-resistance, metabolic syndrome, or healthy-aging questions.
- Languages. Public sources list English and Persian/Farsi; confirm any other language needs before booking.
- Dubai listings differ. She is also listed at Ikigai Medical Centre, so confirm the Biongevity clinic location when scheduling.
