Spec. MD. Coskun Kaya

My 82-year-old father, who has a complex history of atrial fibrillation and mild renal impairment, was visiting from Germany when he developed sudden confusion and weakness. We rushed him to Liv Hospital Bahcesehir without an appointment. Dr. Kaya was immediately consulted. What impressed me wasn't just his rapid diagnosis of a medication interaction (between his blood thinner and a new antibiotic), but his holistic approach. He spent 45 minutes explaining the mechanism to us in simple terms, drew diagrams on his notepad, and coordinated with my father's cardiologist in Frankfurt via email while we were still in the examination room. He didn't just fix the acute issue; he created a 'travel health plan' for my father's future visits. His calm, grandfatherly demeanor eased my father's anxiety completely. We've since switched all our family's care to him.

As a 28-year-old competitive cyclist, I went to Dr. Kaya for what I thought was a routine checkup before a season. I mentioned in passing some occasional heart palpitations during intense climbs, which I'd attributed to exertion. Dr. Kaya didn't dismiss it. He ordered a specific, extended Holter monitor test and discovered paroxysmal supraventricular tachycardia. His approach was incredible: instead of just prescribing medication, he sat down with my training data and heart rate logs, collaborating with a sports cardiologist to design a modified training regimen. He treated me like an athlete, not just a patient. He said, 'Your body is your instrument; we need to tune it, not just fix it.' Thanks to his detective work and preventive mindset, I underwent a successful ablation and am now back to racing, healthier than ever.

Our 6-year-old daughter, Elif, was suffering from recurring, unexplained abdominal pain and fatigue. After several inconclusive pediatric visits, we were referred to Dr. Kaya for an internal medicine perspective. He met her at her level, he had a stuffed animal in his office he used to demonstrate how 'the body's engine' works. He suspected something atypical and ordered a very specific celiac disease panel alongside a comprehensive nutritional absorption workup, which others had overlooked. The diagnosis was a rare, non-classical celiac presentation. But the story doesn't end there. Dr. Kaya provided us with a detailed, child-friendly diet plan, connected us with a pediatric nutritionist, and even followed up with a phone call two weeks later to see how Elif was adapting to the gluten-free diet. His ability to bridge complex internal medicine with compassionate pediatric care was a blessing.

I am a 45-year-old software engineer with a high-stress job and a family history of diabetes. My visit to Dr. Kaya was for a standard executive health screening. The experience was anything but standard. He didn't just read the lab results; he interpreted them through the lens of my lifestyle. He noticed subtle patterns in my liver enzymes and insulin resistance markers that were pre-clinical. His intervention was a detailed, personalized 'metabolic reset' plan, not a generic diet sheet. He used a digital health platform to monitor my progress, sent me relevant research articles, and adjusted the plan in real-time. He framed it as 'system optimization,' which resonated deeply with me. A year later, my biomarkers are in the optimal range. Dr. Kaya practices a form of medicine that is predictive, personalized, and participatory. He turned a routine checkup into a transformative health partnership.
