Dr. Reyna Daya

Reyna Daya is a South African clinician-researcher whose work centers on endocrinology and metabolic disease, with particular emphasis on pheochromocytoma and paraganglioma syndromes, pituitary disorders, and secondary hypertension. Affiliated with major public-sector institutions in South Africa, her scholarship reflects a strong commitment to improving diagnostic pathways and genetic evaluation in resource-limited settings.

Her publications highlight hereditary paraganglioma linked to SDHB mutations, advocating for broader genetic testing across African populations. Additional case-based and review work addresses acromegaly, Cushing’s syndrome, electrolyte disorders, and complex endocrine causes of neuropsychiatric symptoms, demonstrating expertise in rare and diagnostically challenging presentations.

Recent research extends to public health, including analyses of COVID-19 in-hospital mortality and commentary on obesity as a growing epidemic in South Africa. Collectively, these contributions bridge molecular endocrinology, clinical medicine, and population health, underscoring a translational approach that connects genetic insight with real-world healthcare impact.
