Clinical focus

Dr. Hersek sees patients with thyroid disease, which is the subspecialty area of his practice, as well as metabolic conditions more broadly. His areas of expertise include metabolic disease diagnosis and treatment, prediabetes, obesity, fatty liver disease and clinical nutrition. He also evaluates and manages hypertension and anemia, and provides medical treatment and chronic disease management for patients whose conditions require ongoing follow-up rather than a single intervention.

In addition to these long-term conditions, Dr. Hersek treats acute internal medicine problems such as gastroenteritis and upper respiratory tract diseases. Geriatric health is a further area of his practice, and he provides care informed by his experience in age-related health needs, metabolic health and nutrition-related concerns. Where a patient’s situation calls for it, his work centers on medical management and on coordinating the different aspects of a chronic condition over time.

How Dr. Hersek works with international patients

Dr. Hersek speaks Turkish and English, and interpreters can be arranged for patients who need them. Before a visit, the Acibadem international patient team coordinates the collection of prior reports and imaging, including laboratory and pathology results, ultrasound, MRI, CT or X-ray reports, operative notes and discharge summaries, and arranges appointments and the hospital visit itself. A first consultation typically covers the patient’s history and symptoms, a review of existing imaging and previous treatments, a clinical examination and a discussion of the options, so that any further testing or treatment can be planned on the basis of the patient’s individual situation. Video consultation is available for international patients, which may be useful for an initial case review or for follow-up discussion when travel is not immediately possible.
