The scope of general medicine encompasses a vast array of conditions, including:

Cardiovascular Diseases: Hypertension, heart failure, coronary artery disease, arrhythmias.
Respiratory Diseases: Asthma, chronic obstructive pulmonary disease (COPD), pneumonia, bronchitis.
Endocrine Disorders: Diabetes mellitus, thyroid disorders, adrenal insufficiency.
Gastrointestinal Diseases: Irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), peptic ulcer disease.
Renal Diseases: Chronic kidney disease, acute kidney injury, electrolyte imbalances.
Neurological Disorders: Stroke, Parkinson's disease, multiple sclerosis, headaches.
Infectious Diseases: Influenza, pneumonia, urinary tract infections, HIV/AIDS.
Rheumatic Diseases: Rheumatoid arthritis, osteoarthritis, lupus.
Hematological Disorders: Anemia, bleeding disorders, clotting disorders.

Primary Care Physicians: They serve as the first point of contact for adults seeking medical care, providing routine check-ups, managing chronic conditions, and addressing acute illnesses.
Diagnosticians: They are skilled at identifying the underlying causes of complex medical problems, utilizing their knowledge of physiology, pathology, and diagnostic testing.
Treatment Providers: They develop and implement treatment plans, including medication management, lifestyle modifications, and referrals to specialists when necessary.

Depression and Anxiety: Diagnosing and treating mental health conditions through medication, therapy, and lifestyle changes.

Diagnostic Approaches:

Internists utilize a variety of diagnostic tools and techniques to identify the underlying causes of medical problems. These include:

Physical Examination: A thorough physical examination is crucial for assessing a patient's overall health and identifying any abnormalities.
Medical History: Gathering a detailed medical history, including past illnesses, medications, allergies, and family history, provides valuable clues to the diagnosis.
Laboratory Tests: Blood tests, urine tests, and other laboratory analyses can help identify infections, metabolic disorders, and organ dysfunction.
Imaging Studies: X-rays, CT scans, MRI scans, and ultrasound scans can provide detailed images of internal organs and tissues.
Electrocardiogram (ECG): An ECG records the electrical activity of the heart and can help diagnose heart rhythm abnormalities and other cardiac conditions.
Pulmonary Function Tests (PFTs): PFTs measure lung capacity and airflow, helping to diagnose respiratory diseases such as asthma and COPD.
