Chronic kidney disease

Chronic kidney disease (CKD) is a condition in which the kidneys gradually lose their ability to function properly over a long period. The kidneys are essential organs that filter waste products and excess fluids from your blood, help regulate blood pressure, maintain bone health, and make red blood cells. Early detection and management are key to slowing its progression.

What Causes Chronic Kidney Disease?

The most common causes of CKD are:

·        Diabetes: High blood glucose levels can damage the kidneys' filters over time, leading to diabetic kidney disease.

·        High Blood Pressure (Hypertension): Elevated pressure can injure blood vessels in the kidneys, impairing their function

·        Other causes and risk factors include:

o   Heart disease and/or heart failure

o   Obesity and being over age 60

o   Polycystic kidney disease (a genetic disorder)

o   Autoimmune diseases like lupus

o   Long-standing or frequent urinary tract infections

o   Kidney stones or kidney cancer

o   Use of drugs toxic to kidneys (e.g., NSAIDs)

o   Family history of kidney disease

People with a combination of these risk factors are more likely to develop CKD.

Symptoms of Chronic Kidney Disease

CKD often develops silently, with few or no symptoms in its early stages. Many people do not realize they have it until significant kidney damage has occurred. When symptoms do appear, they may include

·        Fatigue and weakness

·        Loss of appetite, nausea, or vomiting

·        Swelling in ankles, feet, or hands (edema)

·        Urinating more or less than usual

·        Shortness of breath or chest pain (from fluid buildup)

·        Trouble sleeping (insomnia)

·        Muscle cramps or twitching

·        Dry, itchy skin

·        High blood pressure that is hard to control

·        Headaches, decreased mental sharpness

If you have these symptoms, consult your healthcare professional.

How is CKD Diagnosed?

Doctors diagnose CKD based on your medical history, physical exam, and simple lab tests. The main tests used include

1. Blood Test for Estimated Glomerular Filtration Rate (eGFR)

·        Measures how well your kidneys filter blood.

·        A lower eGFR suggests reduced kidney function.

2. Urine Test for Albumin-Creatinine Ratio (uACR)

·        Checks how much protein (albumin) is leaking into the urine.

·        Elevated protein levels can be an early sign of kidney problems.

3. Additional Tests

·        Imaging (ultrasound, CT, or MRI scans) to view kidney structure.

·        Kidney biopsy if the cause is uncertain.

·        Regular monitoring if you are at higher risk due to diabetes, hypertension, or a family history of CKD.Blood and urine tests play a crucial role in diagnosing CKD.

Treatment Options for CKD

While CKD cannot be cured, treatment aims to slow its progression, manage symptoms, and prevent complications. Treatment depends on the stage of CKD and usually includes

1. Lifestyle Changes

·        Healthy diet: Low in salt, moderate protein, avoid excessive potassium and phosphorus if advised.

·        Regular exercise: At least 150 minutes per week.

·        Stop smoking and limit alcohol intake.

·        Manage blood sugar and blood pressure.

2. Medications

·        To control blood pressure (ACE inhibitors, ARBs).

·        For diabetes, cholesterol, or other related conditions.

·        Treat anemia or bone disease if present.

3. Dialysis

For advanced CKD (kidney failure), the kidneys can no longer remove enough waste or fluid:

·        Hemodialysis: Blood is filtered outside your body using a machine.

·        Peritoneal dialysis: Blood is filtered inside your abdomen using the peritoneal membrane.

4. Kidney Transplant

Replacing the diseased kidney with a healthy one from a donor. This is often the best long-term solution for severely reduced kidney function.

Living with CKD

·        Regular follow-ups and lab tests are essential to monitor CKD.

·        Take prescribed medications as directed.

·        Stay informed and involved in your care decisions.
