About the department

Our department adopts a three-step service approach to protect and improve your health. In the first step, we identify risk factors using early diagnostic methods before diseases emerge.

In the third and final step, we take preventive measures to improve our patients' quality of life and prevent them from encountering the same health problems again.
Covering a broad medical spectrum, our internal medicine department plays a central role in resolving complex health issues. When necessary, we work in multidisciplinary harmony with other medical specialties in our hospital to determine the best roadmap for your health.
SCOPE OF SERVICES
WHEN SHOULD YOU CONSULT?
Preventive Medicine and Check-Up Services
At BHT CLINIC Istanbul Tema Hospital, we believe that preventing diseases before they occur is the most effective treatment. Accordingly, our expert physicians offer check-up programs tailored to your age, gender, and genetic risk factors. Regular health screenings allow for the early detection of hidden diseases. With our geriatric (advanced age) check-ups, we also take a proactive approach against health problems that may arise in old age.
What Diseases Does Internal Medicine Treat?
Our internal medicine specialists diagnose and treat many acute and chronic conditions encountered during adulthood. The main disease groups treated in our department include:
Diabetes Treatment
Diabetes is a chronic metabolic disease that requires continuous monitoring and care. We aim to diagnose different types, such as Type 1, Type 2, and gestational diabetes, regulate blood sugar, and prevent organ damage. Comprehensive diabetes treatment in Istanbul is meticulously managed by our specialists at Tema Hospital. We aim to help you maintain your quality of life through healthy eating habits and medical treatment planning.
Hypertension and Cardiovascular Risks
Hypertension, commonly known as high blood pressure, can lead to serious problems such as heart attacks and strokes. Your blood pressure is kept under control through regular monitoring, appropriate medication, and lifestyle changes by our experienced hypertension specialists. Additionally, the treatment of conditions threatening cardiovascular health, such as high cholesterol and elevated triglycerides, is successfully managed in our department.
Thyroid and Endocrine System Diseases
Diseases such as underactive or overactive thyroid (hypothyroidism, hyperthyroidism), goiter, and thyroid nodules directly affect your metabolic rate. The diagnosis of these diseases, which manifest with symptoms like fatigue, weight problems, and palpitations, and the restoration of hormone balance are performed by our internal medicine specialists.

Diagnostic Methods Applied
Proper treatment begins with an accurate diagnosis. In our Internal Medicine department, the most up-to-date diagnostic methods offered by modern medicine are used for the definitive diagnosis of diseases:

- Radiological Imaging: The condition of internal organs is examined in detail using advanced imaging technologies such as X-rays, Ultrasonography (USG), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI).
- Endoscopic Procedures: For digestive system complaints, procedures like endoscopy and colonoscopy are planned in coordination with the relevant units when deemed necessary.

Treatment Methods and Applications
Following the diagnostic process, fully personalized treatment plans are created for our patients.

In chronic diseases, nutrition and lifestyle changes are of great importance alongside medical (drug) treatments.
