Chronic Kidney Disease (CKD)

What Is Chronic Kidney Disease?

Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to filter waste, excess fluids, and toxins from the blood. This damage usually occurs over months or years and may worsen if not properly managed.

The kidneys play a vital role in:

    • Removing waste products from the blood

    • Balancing fluids and electrolytes

    • Regulating blood pressure

    • Supporting red blood cell production

    • Maintaining bone health

When kidney function declines, waste can build up in the body and lead to serious health problems.

Stages of Chronic Kidney Disease

CKD is classified into five stages, based on how well the kidneys are filtering blood (measured by estimated glomerular filtration rate, or eGFR):

    • Stage 1–2: Mild kidney damage with normal or slightly reduced function

    • Stage 3: Moderate loss of kidney function

    • Stage 4: Severe loss of kidney function

    • Stage 5: Kidney failure (end-stage kidney disease), requiring dialysis or transplant

Early detection can slow or prevent progression.

Symptoms of Chronic Kidney Disease

Early CKD often has no symptoms. As kidney function declines, symptoms may include:

    • Fatigue or weakness

    • Swelling of the feet, ankles, or face

    • Changes in urination (frequency, color, or amount)

    • Shortness of breath

    • Nausea or vomiting

    • Difficulty concentrating

    • Muscle cramps or itching

How Is CKD Diagnosed?

CKD is diagnosed through:

    • Blood tests (to measure creatinine and eGFR)

    • Urine tests (to check for protein or blood)

    • Blood pressure measurements

    • Imaging tests (such as ultrasound)

Regular screening is important for people at high risk.

When to See an AKDHC Provider

Seek medical advice if you:

    • Have diabetes or high blood pressure

    • Notice swelling, fatigue, or changes in urination

    • Have abnormal blood or urine test results

Treatment for Chronic Kidney Disease

There is no cure for CKD, but treatment can slow disease progression, relieve symptoms, and reduce complications.

Lifestyle and Dietary Changes

Healthy habits are essential in managing CKD:

    • Control blood sugar and blood pressure

    • Follow a kidney-friendly diet (lower sodium, protein, phosphorus, and potassium as advised)

    • Maintain a healthy weight

    • Exercise regularly

    • Avoid smoking

    • Limit alcohol intake

A dietitian may help create a personalized nutrition plan.

Medications

Depending on the stage and cause of CKD, medications may include:

    • Blood pressure medications (ACE inhibitors or ARBs)

    • Diabetes medications

    • Diuretics to manage fluid buildup

    • Medications to control cholesterol

    • Treatments for anemia or bone disease

Comprehensive Chronic Kidney Disease Management

At AKDHC, we provide personalized care for patients with CKD at every stage. When CKD is identified early and managed appropriately, progression can often be slowed.

Preserving Kidney Function
    • Slowing the progression of kidney disease and protecting remaining kidney function
    • Individualized treatment plans based on CKD stage and underlying causes
    • Regular monitoring of kidney function and urine abnormalities
Medication Safety & Optimization
    • Comprehensive medication review to identify and reduce exposure to nephrotoxic agents
    • Dose adjustments based on kidney function
    • Coordination with primary care and specialty providers to ensure safe prescribing
Management of CKD-Related Complications
    • Early recognition and treatment of anemia

    • Evaluation and management of mineral and bone disorders

    • Monitoring and correction of electrolyte imbalances

    • Blood pressure optimization to protect kidney and cardiovascular health

Nutrition & Patient Education
    • Referral for individualized nutritional counseling tailored to CKD stage

    • Education on sodium, protein, potassium, and phosphorus management

    • Guidance on lifestyle changes that support kidney health

Advanced Care Planning
    • Early preparation for renal replacement therapy when needed

    • Education on dialysis options (hemodialysis and peritoneal dialysis)

    • Timely referral and preparation for kidney transplantation

    • Educational support during transition planning

Living With Chronic Kidney Disease

With proper management, many people with CKD live full, active lives. Ongoing care includes regular lab tests, medication adherence, and lifestyle adjustments to protect remaining kidney function.
