Internal Medicine

Internal medicine is the main branch of medicine that comprehensively examines the internal organ systems of adults and undertakes the diagnosis and pharmacological treatment of chronic and acute diseases.

Internal medicine is a broad branch of medicine encompassing the diagnosis, treatment, and follow-up of diseases in adult individuals. This branch of medicine, which involves many systems of the body, plays a vital role in the initial assessment and management of numerous health problems, ranging from cardiovascular diseases and diabetes to infections and digestive system disorders.

What is Internal Medicine?

Internal medicine is the branch of medicine that deals with the diagnosis, treatment, and follow-up of diseases of the internal organs and systems in adult individuals. This branch of medicine, encompassing many systems of the body, evaluates the patient not solely based on a single complaint, but also on their general health status.

Internal medicine takes a holistic approach to symptoms related to different systems, including the heart, lungs, digestive system, kidneys, hormones, and blood. This allows for the accurate investigation and evaluation of the underlying causes of various complaints such as fatigue, weight changes, palpitations, or digestive problems.

What diseases does Internal Medicine treat?

Internal medicine deals with the diagnosis, treatment, and follow-up of numerous systemic diseases seen in adult individuals. This field of study is quite broad, and different disease groups can be evaluated according to the relevant systems. The diseases that this department deals with are:

Metabolic and Endocrine Diseases

Diabetes: It occurs when blood sugar levels remain uncontrolled and requires regular monitoring.
Insulin resistance: It develops as a result of a decreased response of the body to insulin and can increase the risk of diabetes.
Thyroid Diseases: Both an underactive and overactive thyroid gland can affect the body's general balance.
High cholesterol and triglycerides: These are lipid metabolism disorders that can negatively affect vascular health.
Obesity: This is a condition that poses a risk for many chronic diseases and needs to be evaluated from a metabolic perspective.

Cardiovascular Diseases

Hypertension: High blood pressure can affect heart, kidney, and vascular health in the long term.
Hypotension: Low blood pressure can cause weakness, dizziness, and a feeling of faintness.
Risk of atherosclerosis: Risk factors that predispose to cardiovascular disease can be evaluated by internal medicine specialists.
Edema: It can develop due to fluid accumulation in the body, and underlying systemic causes are investigated.

Digestive System Diseases

Gastritis: It is a condition that develops due to inflammation of the inner lining of the stomach and can lead to symptoms such as burning and pain.
Reflux: It occurs when stomach contents leak back into the esophagus and can cause a frequently recurring burning sensation.
Ulcer: It is a digestive system disease characterized by the formation of ulcers in the stomach or duodenum.
Irritable bowel syndrome: Abdominal pain, bloating, and changes in bowel habits may occur.
Constipation and diarrhea: These are common complaints affecting the functioning of the digestive system that require investigation to determine the cause.
Fatty liver disease: It is a common liver problem that can develop especially in association with metabolic risks.
Hepatitis and liver dysfunction: Diseases affecting the liver may require an internal medicine evaluation.

Kidney and Urinary Tract Diseases

Kidney dysfunction: The kidneys may experience a decrease in their capacity to filter waste from the body.
Urinary tract infections: It can manifest with symptoms such as frequent urination, burning, and pain.
Protein leakage: The presence of protein in the urine is a finding that should be investigated in terms of kidney health.
Kidney Failure: It is a serious condition that develops as a result of the kidneys being unable to perform their functions adequately.
Electrolyte imbalances: Disruptions in levels such as sodium and potassium may be related to kidney and metabolic processes.

Blood Diseases

Anemia: Low hemoglobin levels in the blood can cause weakness and fatigue.
Iron deficiency: It is one of the most common causes of anemia and requires a thorough evaluation.
Vitamin B12 deficiency: It is a significant deficiency affecting the nervous system and blood production.
Folic acid deficiency: This is one of the vitamin deficiencies that can affect the production of blood cells.
Suspected clotting disorders: Bleeding or clotting problems can initially be evaluated by internal medicine specialists.

Infectious Diseases and General Internal Problems

Prolonged fever: In cases of unexplained fever, underlying infections or systemic causes are investigated.
Malaise and fatigue: Because it can be a common symptom of many internal diseases, it requires a detailed examination.
Unexplained weight loss: It could be a sign of metabolic, infectious, or systemic diseases.
Night sweats: This is an important symptom that can be associated with certain infections or systemic diseases.
Loss of appetite: It is a general health issue that should be evaluated on its own or in conjunction with other symptoms.

Internal Conditions Related to the Respiratory System

Persistent cough: It may be related to infection, reflux, or systemic causes and should be investigated.
Shortness of breath: Because it could be of cardiac, pulmonary, or metabolic origin, it may require evaluation by an internal medicine specialist.
Prolonged upper respiratory tract infections: In some cases, it may need to be considered in conjunction with the general health condition.

Conditions Associated with Rheumatic and Systemic Findings

Joint pain: It is evaluated because it could be a symptom of rheumatic or systemic diseases.
Muscle pain: It can occur for a variety of reasons, from vitamin deficiencies to infections.
Unexplained elevated inflammation levels: It could be a sign of various ongoing disease processes in the body.
Suspected connective tissue disease: Some conditions that present with systemic symptoms may initially be evaluated by an internal medicine specialist.

Conditions Requiring Chronic Disease Monitoring

Diabetes follow-up: Regular monitoring of blood sugar levels is important for preventing complications.
Hypertension monitoring: Long-term control of blood pressure is essential for cardiovascular health.
Monitoring thyroid diseases: Regular monitoring of hormone levels supports treatment success.
Monitoring high cholesterol levels: Regular monitoring is carried out to reduce the risk of vascular diseases.
Simultaneous management of multiple chronic diseases: Internal medicine ensures the holistic monitoring of concurrent health problems.

What are the diagnostic methods for internal medicine?

Diagnostic methods in internal medicine are determined by evaluating the patient's complaints, performing a physical examination, and using a combination of various tests. Internal medicine specialists conduct a comprehensive analysis, considering different methods together to arrive at an accurate diagnosis. The main diagnostic methods are as follows:

Blood tests: It provides important information about infections, anemia, hormonal imbalances, and organ function.
Urinalysis: It provides insights into kidney health, infections, and metabolic diseases.
Biochemistry tests: Values related to the liver, kidneys, electrolytes, and metabolism are analyzed.
Hormone tests: The functioning of the thyroid and other hormone glands is assessed.
Stool tests: Conditions such as digestive system disorders and occult bleeding are investigated.
Allergy Tests: The immune system's responses to specific substances are evaluated.
Blood pressure measurement: High or low blood pressure conditions are evaluated for diagnosis and monitoring purposes.

Advanced Diagnostic and Imaging Methods

Electrocardiography (ECG): Rhythm and conduction disorders are evaluated by measuring the electrical activity of the heart.
Pulmonary function tests: Respiratory system diseases are investigated by measuring lung capacity and respiratory functions.
X-ray and ultrasonography: These are rapid and widely used imaging methods for basic structural assessment of internal organs.
Computed tomography (CT) and MRI: It provides detailed and layered imaging of organs, allowing for more advanced evaluation.
Endoscopy and colonoscopy: Direct imaging of the digestive system helps in the diagnosis of stomach and intestinal diseases.
Bone density measurement: Bone mineral density is assessed to determine the risk of osteoporosis.
Holter monitoring: Changes in heart rhythm or blood pressure during daily life are monitored over the long term.
Biopsy: Samples are taken from the suspicious tissues and subjected to microscopic examination.

What are the treatment methods for internal medicine?

Internal medicine treatment methods consist of medication, lifestyle adjustments, supportive therapies, and regular follow-ups, all planned according to the type, severity, duration of the disease, and the patient's general health condition. In internal medicine, the treatment approach is often not limited to a single method; in many diseases, medication, dietary regimen, exercise, weight control, and monitoring are carried out together. The main treatment methods are as follows:

Drug Treatments

Blood pressure medications: It is used to control high blood pressure and prevent organ damage.
Blood sugar regulators: It helps keep blood sugar levels balanced in diabetic patients.
Cholesterol-lowering drugs: It is preferred for protecting vascular health and reducing risks.
Thyroid medications: It is used to balance conditions where the thyroid hormone is underactive or overactive.
Vitamin and mineral therapies: It replaces the nutrients the body needs when there is a deficiency.

Lifestyle Modifications

Healthy eating: Disease-specific dietary plans form the basis of treatment.
Regular exercise: It supports metabolism, contributing to the control of many diseases.

Smoking and alcohol restrictions: It improves general health, thereby increasing the success of treatment.

Supportive Treatments

Symptom control: It provides support to reduce symptoms such as pain, palpitations, or fatigue.
Nutrition counseling: It strengthens treatment, especially in patients with diabetes and high cholesterol.

Advanced and Interventional Approaches

Radioiodine therapy: It can be applied in certain situations in thyroid diseases.
Referral for surgery: Referrals to relevant departments are made when necessary.
Hormone replacement therapy: In conditions such as thyroid insufficiency (hypothyroidism) or adrenal gland insufficiency, the body's balance is restored by administering the hormones that the body is not producing adequately.

Monitoring and Tracking Processes

Regular blood tests: It is used to evaluate the effectiveness of the treatment.
Blood pressure and blood sugar monitoring: It helps keep chronic diseases under control.
Drug dosage adjustments: The treatment plan is updated according to the patient's condition.
