About Kidney Disease

Name of the medical condition and other names that it’s been known by

• Kidney Disease

• Renal Disease

• Nephropathy

What is Kidney Disease?

Your kidneys are two small, bean-shaped organs in your back, just below your rib cage. Their main job is to clean your blood by removing waste and extra water, balancing minerals, controlling blood pressure, and assisting in the production of red blood cells. Kidney disease occurs when these organs are damaged and can no longer perform these essential functions effectively.

What are the main types of Kidney Disease?

• Chronic Kidney Disease (CKD): The most common type, where kidney function declines slowly over many years. It is categorized into five stages, with Stage 5 representing kidney failure or end-stage renal disease (ESRD).

• Acute Kidney Injury (AKI): A sudden loss of kidney function, often resulting from serious injury, severe infection, or reaction to certain medications.

What are common symptoms of Kidney Disease?

• Feeling tired or weak

• Swelling in the ankles, feet, or hands (edema)

• Shortness of breath

• Upset stomach or vomiting

• Trouble sleeping

• Changes in urination frequency

• Muscle cramps and itchy skin

How is Kidney Disease Diagnosed?

Doctors use several diagnostic tools to assess kidney health:

• Medical History & Physical Exam: Checking for symptoms, family history, and lifestyle factors.

• Blood Tests: Measuring waste products like creatinine to determine how well the kidneys are filtering.

• Urine Tests: Checking for the presence of protein (albumin) or blood, which are early signs of damage.

• Imaging Tests: Ultrasounds or CT scans to observe the size, shape, and structure of the kidneys.

• Biopsy: Taking a small tissue sample to examine under a microscope if the cause of damage is unclear.

How is Kidney Disease Treated?

While there is no cure for chronic kidney disease, treatment aims to slow its progression:

• Management of Underlying Causes: Controlling blood pressure and blood sugar is the most critical step to prevent further damage.

• Medications: Using ACE inhibitors or ARBs for blood pressure, as well as newer medications designed to protect kidney function.

• Dietary Changes: Reducing salt and protein intake to lower the workload on the kidneys.

• Healthy Habits: Maintaining a healthy weight, staying active, and avoiding smoking.

Advanced Treatment for Kidney Failure

• Dialysis: A mechanical process that filters waste and extra fluid from the blood when the kidneys can no longer do so.

• Kidney Transplant: Surgical placement of a healthy donor kidney, which is typically the most effective long-term solution.

Trend

• In the United States: Approximately 37 million adults (1 in 7) have CKD. Many are unaware of their condition because early stages often lack symptoms.

• Rising Rates: Diagnoses are increasing annually, largely driven by the rising prevalence of diabetes and hypertension.

• Projections: Experts expect cases to continue rising over the next five years as the population ages and chronic lifestyle diseases become more common.

History

Kidney ailments have been documented since antiquity in Egyptian and Greek texts. In the 1800s, Dr. Richard Bright’s extensive research led to these conditions being called "Bright’s Disease." The 20th century saw the most significant advancements, including the invention of the first dialysis machine and the successful execution of the first kidney transplants.
