Internal Medicine

Internal Medicine is one of the most comprehensive and fundamental branches of medicine, specializing in the diagnosis, treatment, and follow-up of internal organ diseases in adult patients. Also known as Internal Diseases, this department covers a wide spectrum of diseases involving various organs and systems, such as the heart, lungs, liver, kidneys, gastrointestinal system, blood disorders, endocrine system, and rheumatological diseases. The Koru Hospital Internal Medicine Department provides comprehensive healthcare services to its patients with its experienced specialist staff and advanced technological infrastructure.

What is Internal Medicine and Which Diseases Does It Treat?

Internal medicine specialists (internists) are physicians who play a primary role in the diagnosis and treatment of diseases affecting the functioning of internal organs in the body. This department is considered the first point of contact for patients, and referrals to relevant sub-specialties are made when necessary. The main disease groups treated by the internal medicine department are as follows:

• Diabetes: Diagnosis of Type 1 and Type 2 diabetes, assessment of insulin resistance, blood sugar regulation, and prevention of diabetic complications
• Hypertension (High Blood Pressure): Blood pressure monitoring, regulation of medication therapy, and assessment of target organ damage
• Thyroid Diseases: Follow-up of hypothyroidism, hyperthyroidism, thyroid nodules, and autoimmune thyroid diseases
• Liver Diseases: Hepatitis, fatty liver, cirrhosis, and liver dysfunction
• Kidney Diseases: Chronic kidney failure, kidney stones, and urinary tract infections
• Anemia and Blood Disorders: Iron deficiency anemia, Vitamin B12 deficiency, and other hematological issues
• Rheumatological Diseases: Rheumatoid arthritis, gout, and connective tissue diseases
• Respiratory System Diseases: Asthma, COPD, pneumonia, and respiratory tract infections
• Gastrointestinal Diseases: Gastritis, ulcers, reflux, irritable bowel syndrome, and inflammatory bowel diseases

Diagnostic Methods in Internal Medicine

In modern medicine, internal medicine diagnostic methods have shown significant development. The Koru Hospital Internal Medicine Department utilizes comprehensive diagnostic tools for the early and accurate diagnosis of diseases. The main methods applied during the diagnostic process are as follows:

Laboratory Tests

Blood tests form one of the cornerstones of internal medicine practice. Comprehensive laboratory examinations such as complete blood count (CBC), biochemistry panels, hormone tests, tumor markers, autoantibody panels, and urinalysis are performed. These tests make it possible to detect diseases at an early stage and effectively monitor the treatment process.

Imaging Methods

Advanced imaging techniques such as ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and plain X-rays play an indispensable role in the diagnosis of internal medicine diseases. Ultrasonography is frequently preferred for the evaluation of intra-abdominal organs, thoracic CT for lung diseases, and MRI for liver pathologies.

Endoscopic Examinations

Endoscopic procedures such as upper gastrointestinal endoscopy and colonoscopy are considered the gold standard in the diagnosis of gastrointestinal system diseases. These methods allow for both visual assessment and, when necessary, biopsy for histopathological examination.

Chronic Disease Management

Chronic disease management is one of the most important components of internal medicine practice. Regular check-ups and treatment planning are of great importance for diseases requiring long-term follow-up, such as diabetes, hypertension, chronic kidney disease, heart failure, and chronic obstructive pulmonary disease (COPD).

Approaches applied within the scope of chronic disease management at the Koru Hospital Internal Medicine Department include:

• Individualized treatment plans: Personalized treatment protocols are created by considering each patient's age, gender, comorbidities, and living conditions
• Regular follow-up examinations: The course of the disease is closely monitored through periodic check-ups
• Optimization of medication therapy: Medication doses and combinations are adjusted by evaluating the response to treatment and potential side effects
• Lifestyle change counseling: Patients are informed about nutrition, exercise, stress management, and weight control
• Complication screening: Periodic screenings are performed for the early detection of damage that chronic diseases may cause to target organs

Preventive Healthcare Services in Internal Medicine

Preventive medicine is an approach that aims to prevent diseases before they occur or to catch them at an early stage. Preventive healthcare services offered in the internal medicine department include:

Check-Up Programs

Check-up programs, known as general health screenings, enable the early diagnosis of potential diseases in seemingly healthy individuals. Comprehensive health assessments are conducted by preparing personalized check-up packages based on age, gender, and risk factors. These screenings include blood tests, imaging examinations, cardiological evaluations, and cancer screening tests.

Vaccination and Immunization

The administration of preventive vaccines such as the flu vaccine, pneumococcal vaccine, Hepatitis B vaccine, and shingles vaccine in adults falls under the responsibility of the internal medicine department. Vaccination programs are of vital importance, especially for individuals with chronic diseases, those with suppressed immune systems, or the elderly.

Risk Factor Assessment

Individuals' disease risk profiles are determined by considering family history, genetic predisposition, lifestyle habits, and environmental factors. Special follow-up and preventive treatment programs are implemented for high-risk individuals.

Diabetes Management and Metabolic Syndrome

Diabetes affects millions of people today as one of the most common chronic diseases worldwide. A significant portion of the adult population in Turkey also has diabetes or prediabetes. Services provided within the scope of diabetes management in the internal medicine department include:

• Diabetes screening and diagnosis with Oral Glucose Tolerance Test (OGTT)
• Assessment of long-term blood sugar control with HbA1c monitoring
• Insulin therapy planning and dose adjustment
• Selection of oral antidiabetic drugs and combination therapies
• Screening for complications such as diabetic foot, retinopathy, nephropathy, and neuropathy
• Nutritional counseling and diabetes education

Metabolic syndrome is a condition characterized by the coexistence of risk factors such as abdominal obesity, insulin resistance, hypertension, and dyslipidemia. Early diagnosis and management of this syndrome are critical in reducing the risk of cardiovascular disease.

Anemia and Hematological Diseases

Anemia is a very common health problem in the community and is frequently encountered in internal medicine practice. Iron deficiency anemia, Vitamin B12 deficiency, folic acid deficiency, and anemia of chronic disease are the most common types of anemia. Internal medicine specialists determine the cause of the anemia and plan the appropriate treatment approach.

The main steps applied in the anemia diagnosis and treatment process are:

• Complete blood count and peripheral smear examination
• Measurement of iron parameters (ferritin, iron, iron-binding capacity)
• Assessment of Vitamin B12 and folic acid levels
• Evaluation of bone marrow response with reticulocyte count
• Investigation and treatment of the underlying cause
• Oral or intravenous iron replacement, Vitamin B12 injections

Liver and Gastrointestinal Diseases

Liver diseases are health problems frequently encountered in the internal medicine department that can lead to serious consequences. Viral hepatitis (Hepatitis A, B, C), non-alcoholic fatty liver disease, alcoholic liver disease, and autoimmune hepatitis are the main diseases in this group. Symptoms such as elevated liver enzymes, jaundice, abdominal swelling, and itching are important signs of liver disease.

In terms of gastrointestinal system diseases, gastritis, gastroesophageal reflux disease (GERD), peptic ulcer, irritable bowel syndrome, inflammatory bowel diseases (Crohn's disease and ulcerative colitis), and celiac disease are among the pathologies frequently evaluated in internal medicine practice.

Multidisciplinary Approach in Internal Medicine

A multidisciplinary approach is extremely important, especially in complex diseases affecting multiple systems. Internal medicine specialists provide a holistic treatment plan for the patient by working in coordination with sub-specialties such as cardiology, nephrology, gastroenterology, endocrinology, hematology, rheumatology, and pulmonology.

Services offered by the internal medicine department at Koru Hospital within the scope of multidisciplinary work include:

• Consultation services and joint decision-making in complex cases
• Preoperative evaluation and risk analysis before surgery
• Internal medicine consultation follow-up for intensive care patients
• Supportive care and complication management for oncology patients
• Comprehensive assessment of geriatric patients and regulation of polypharmacy
