Assoc. Prof. MD. Ihsan Ustun

I was rushed to Medical Park Mersin with a thyroid storm, my heart was racing, I had a 104°F fever, and I was delirious. Dr. Ihsan Ustun took over my case in the ICU. Within hours, he stabilized me with a precise cocktail of medications I'd never heard of. He explained to my terrified family that my Graves' disease had spiraled, but he had it under control. His calm, commanding presence during that crisis was literally life-saving. Three days later, I was coherent; two weeks later, we were planning my radioactive iodine therapy. He didn't just treat a number; he rescued a person from the brink.

My 8-year-old daughter was diagnosed with Type 1 diabetes at another clinic, and we were given a generic pamphlet and a scared look. We sought a second opinion with Dr. Ustun. He got down on her level, showed her his 'superhero glucose monitor,' and turned carb counting into a game. For us, parents, he drew clear diagrams of insulin action curves. He set up a WhatsApp group with his nurse for 24/7 questions, no charge. It's been 18 months. Her HbA1c is 6.2, and she manages her pump with confidence. He didn't just treat a child; he empowered our whole family to live without fear.

As a 72-year-old with osteoporosis and a recent hip fracture, I'd seen many doctors. Dr. Ustun was different. He spent an hour reviewing my bone density scans, asking about my diet, my garden (I love gardening), and my fear of falling again. He crafted a plan that wasn't just a pill: specific balance exercises, a vitamin D protocol tailored to my kidney function, and a novel osteoanabolic agent. At my 6-month follow-up, he showed me the imaging, my bone microarchitecture had improved. He treats you like a whole person, not just a brittle bone. I garden again, with care, but without terror.

I'm a 45-year-old chef with a puzzling case: wildly fluctuating calcium levels, kidney stones, and fatigue. Three endocrinologists before him called it 'atypical hyperparathyroidism' and suggested watchful waiting. Dr. Ustun, after reviewing my records, suspected a rare genetic form, Familial Hypocalciuric Hypercalcemia. He ordered a specific genetic panel and a sestamibi scan that others deemed unnecessary. He was right. I had a single, ectopic parathyroid adenoma hiding near my heart. He coordinated with a thoracic surgeon for a minimally invasive procedure. Post-surgery, my calcium normalized. He solved a medical mystery that others had dismissed. His diagnostic courage is exceptional.
