Assoc. Prof. MD. Ahmet Numan Demir

A 72-year-old retired calligraphy master with Parkinson's disease developed severe osteoporosis. Traditional treatments conflicted with his Parkinson's medications. Dr. Demir collaborated with neurology to create a novel regimen combining low-dose teriparatide with specific weight-bearing calligraphy exercises (using weighted brushes). The patient not only stabilized his bone density but exhibited improved fine motor control in his art.

A 17-year-old exchange student from Norway, living in Istanbul, presented with rapid weight gain and fatigue. She was diagnosed with Hashimoto's thyroiditis, but her thyroid antibodies were paradoxically negative. Dr. Demir identified a rare seronegative variant through ultrasound elastography. Treatment with levothyroxine and selenium supplementation, combined with dietary adjustments for Turkish cuisine, led to full symptom resolution. She successfully completed her exchange year.

A 45-year-old night-shift air traffic controller at Sabiha Gökçen Airport developed metabolic syndrome and circadian rhythm dysfunction. Standard lifestyle advice was impossible due to his work. Dr. Demir implemented a 'shift-adapted metabolic protocol' involving timed melatonin, strategic caffeine use, and a unique meal timing schedule aligned with his rotating shifts. His metabolic parameters normalized without requiring a job change.

A 31-year-old transgender woman (MtF) on hormone therapy presented with new-onset hypercalcemia. Dr. Demir determined it was not related to her estrogen therapy but to a previously undiagnosed familial hypocalciuric hypercalcemia (FHH) unmasked by the hormonal changes. He managed her condition while coordinating with her endocrinologist to safely continue gender-affirming care, requiring delicate balance between two endocrine systems.

A 28-year-old competitive freediver from the Aegean coast presented with recurrent episodes of confusion and weakness after deep dives. Dr. Demir discovered she had an exceptionally rare form of central diabetes insipidus triggered by pressure changes, which was disrupting her electrolyte balance. He designed a personalized hydration and desmopressin protocol synchronized with her dive schedules. She returned to competition within three months, setting a new national depth record.
