Internal Medicine and Nephrology Overview

Internal Medicine Overview

• Internal medicine is a broad medical specialty focused on diagnosing, treating, and preventing adult diseases.
• It covers diverse organ systems and conditions, including cardiovascular, pulmonary, gastrointestinal, endocrine, hematologic, and infectious diseases.
• Internists are physicians specializing in internal medicine.
• They provide comprehensive care for patients with both chronic and acute conditions.

Nephrology Overview

• Nephrology is a subspecialty of internal medicine focused on the kidneys and related conditions.
• Nephrologists specialize in the diagnosis and treatment of kidney diseases.
• They manage conditions like acute and chronic kidney injury, glomerulonephritis, nephrotic syndrome, hypertension, and kidney stones.
• Nephrologists often work with other specialists (e.g., cardiologists, endocrinologists) for comprehensive kidney care.
• Diagnosis includes patient history, physical examinations, and relevant tests for renal disorders.

Kidney Function and Related Diseases

• Kidneys maintain homeostasis by filtering waste and excess fluid from the blood, regulating blood pressure, and producing hormones.
• Chronic kidney disease (CKD) is a gradual loss of kidney function.
• Common causes of CKD include diabetes, hypertension, glomerulonephritis, and polycystic kidney disease.
• CKD symptoms can be subtle, including fatigue, nausea, and changes in urine output.
• Early detection is vital for managing CKD progression.

Diagnosis and Treatment in Nephrology

• Diagnosing kidney ailments often involves blood tests (e.g., creatinine, BUN), urine tests, imaging (e.g., ultrasound, CT scan), and kidney biopsies.
• Treatment varies based on the specific kidney disorder.
• Treatments may include medications for blood pressure, diabetes, or other underlying causes, dietary restrictions, dialysis, or kidney transplantation.
• Dialysis artificially filters the blood when kidneys cannot adequately do so.

Hypertension and Kidney Disease

• Hypertension (high blood pressure) significantly increases the risk of kidney disease.
• Uncontrolled high blood pressure damages kidney blood vessels over time.
• Managing hypertension helps prevent and slow down kidney disease progression.

Glomerulonephritis

• Glomerulonephritis is inflammation of the glomeruli (kidney filtering units).
• Causes include infections, autoimmune diseases, and certain medications.
• Symptoms range from mild to severe, including proteinuria, hematuria, and edema.
• Treatment depends on the underlying cause.

Acute Kidney Injury (AKI)

• AKI is a sudden decline in kidney function, typically occurring over hours or days.
• AKI causes include sepsis, dehydration, medications, and urinary tract obstructions.
• Prompt diagnosis and treatment are vital to prevent progression to chronic kidney disease.

Chronic Kidney Disease (CKD) and its Stages

• CKD is a progressive loss of kidney function over months or years.
• CKD stages depend on the glomerular filtration rate (GFR), a measure of kidney filtering efficiency.
• Early CKD often has no noticeable symptoms; regular checkups are crucial.
• Advanced CKD may require dialysis or kidney transplantation.

Kidney Stones

• Kidney stones are solid masses formed from minerals and salts in the urine.
• Risk factors for kidney stones include dehydration, high-mineral diets, and specific medical conditions.
• Diagnosis involves imaging and stone analysis.
• Treatment ranges from pain management for small stones to surgery for larger, obstructive stones.

Dialysis and Kidney Transplantation

• Dialysis filters waste and excess fluid from the blood when kidneys are not functioning adequately.
• Types include hemodialysis and peritoneal dialysis.
• Kidney transplantation involves surgically placing a healthy donor kidney into a recipient with failing kidneys.

Important Considerations in Nephrology Practice

• Patient collaboration and communication are vital for treatment success.
• Diet, fluid intake, and lifestyle modifications are essential parts of managing kidney disorders.
• Ongoing monitoring and follow-up care are critical in managing chronic kidney disease.
• Psychosocial support for patients and their families plays a significant role in nephrology care.
