A Complete Guide for Patients and Families
More than 35.5 million Americans—1 in 7 adults—are living with chronic kidney disease. Yet remarkably, 9 out of 10 people with CKD don’t even know they have it. This “silent disease” often progresses without symptoms until significant kidney damage has occurred, making awareness, early detection, and proper management absolutely critical.
For seniors and their families navigating a CKD diagnosis, the path forward can feel overwhelming. Between dietary restrictions, medication schedules, medical appointments, and the fatigue that often accompanies kidney disease, daily life becomes increasingly challenging. That’s where professional home care can make a profound difference—helping patients manage their condition, maintain their independence, and enjoy a better quality of life.
Understanding Chronic Kidney Disease: The Basics
Chronic kidney disease describes the gradual loss of kidney function over time. Your kidneys—two bean-shaped organs located on either side of your spine—perform several essential functions that are vital to your overall health.
What Do Healthy Kidneys Do?
Filter waste and toxins: Each day, your kidneys filter approximately 120-150 quarts of blood, removing waste products that are then eliminated through urine.
Regulate fluid balance: The kidneys maintain proper water and electrolyte balance (sodium, potassium, calcium, phosphorus) in the body.
Control blood pressure: The kidneys produce renin, an enzyme that helps regulate blood pressure by controlling blood vessel constriction.
Stimulate red blood cell production: The kidneys produce erythropoietin (EPO), a hormone that signals your bone marrow to make red blood cells.
Maintain bone health: The kidneys activate vitamin D, which is essential for calcium absorption and bone strength.
Balance acid levels: The kidneys help maintain proper acid-base balance in the blood.
When kidney function declines, these processes become impaired, leading to a cascade of symptoms and health complications.
Chronic Kidney Disease: The Statistics (2024-2025)
Understanding the scope of kidney disease helps illustrate why awareness and management matter so much.
Prevalence in the United States
| Statistic | Data |
|---|---|
| Americans with CKD | 35.5 million (14% of adults) |
| Unaware they have CKD | 9 in 10 adults with CKD |
| Adults with diabetes who have CKD | 1 in 3 |
| Adults with high blood pressure who have CKD | 1 in 5 |
| Americans living with kidney failure (ESKD) | 815,000 |
| Americans on dialysis | 555,000 |
| People on the kidney transplant waiting list | 90,000+ |
| Kidney transplants performed in 2024 | 28,492 |
Age and Risk Factors
| Age Group | CKD Prevalence |
|---|---|
| Ages 18-44 | 6% |
| Ages 45-64 | 12% |
| Ages 65 and older | 34% |
CKD is significantly more common among seniors, with more than one-third of adults over 65 affected. This makes kidney health a particularly important consideration for older adults and their caregivers.
The Financial Burden
- Medicare spending on CKD patients (excluding ESKD) ages 66+: $77 billion in 2021
- Annual per-person expenditures for Medicare beneficiaries with CKD: $28,162 (more than double that of those without CKD)
- Total Medicare spending on ESKD: $52.3 billion in 2021
Racial and Ethnic Disparities
Kidney disease does not affect all populations equally:
- Black Americans are 4 times more likely to develop kidney failure
- Hispanic Americans are more than 2 times more likely to develop kidney failure
- Diabetes causes approximately 45% of new kidney failure cases
The Five Stages of Chronic Kidney Disease
CKD is classified into five stages based on kidney function, measured by the estimated glomerular filtration rate (eGFR). Understanding these stages helps patients and caregivers know what to expect and how to plan for care needs.
Stage 1: Kidney Damage with Normal Function
- eGFR: 90 or higher
- Kidney function: 90% or more
- Symptoms: Usually none
- Care focus: Identify and treat underlying causes; control blood pressure and blood sugar
Stage 2: Mild Loss of Kidney Function
- eGFR: 60-89
- Kidney function: 60-89%
- Symptoms: Usually none
- Care focus: Continue managing risk factors; annual monitoring
Stage 3a: Mild to Moderate Loss of Function
- eGFR: 45-59
- Kidney function: 45-59%
- Symptoms: May include fatigue, appetite changes, and urination changes
- Care focus: Nephrology referral; dietary modifications; medication adjustments
Stage 3b: Moderate to Severe Loss of Function
- eGFR: 30-44
- Kidney function: 30-44%
- Symptoms: Fatigue, shortness of breath, appetite loss, and urination changes
- Care focus: More frequent monitoring; address complications like anemia and bone disease
Stage 4: Severe Loss of Kidney Function
- eGFR: 15-29
- Kidney function: 15-29%
- Symptoms: Swelling (hands, feet, face), back pain, sleep difficulties, concentration problems, nausea
- Care focus: Prepare for kidney replacement therapy; discuss dialysis or transplant options
Stage 5: Kidney Failure (End-Stage Kidney Disease)
- eGFR: Less than 15
- Kidney function: Less than 15%
- Symptoms: Severe fatigue, swelling, minimal or no urination, weight loss, nausea, itching
- Care focus: Dialysis or a kidney transplant is required to survive
Recognizing the Symptoms of Kidney Disease
One of the most challenging aspects of CKD is that early stages often produce no symptoms. By the time symptoms appear, significant kidney damage may have already occurred. This is why regular screening is so crucial for people at risk.
Common Symptoms of Advanced CKD
Fatigue and Weakness: When the kidneys can’t filter waste properly, toxins accumulate in the blood, causing persistent fatigue. Additionally, reduced erythropoietin production leads to anemia, further contributing to fatigue.
Swelling (Edema): Failing kidneys cannot remove excess fluid from the body. This fluid accumulates in the ankles, feet, legs, hands, and face—a condition called edema.
Shortness of Breath: Fluid accumulation in the lungs and anemia reduce oxygen delivery to tissues, both contributing to breathlessness.
Changes in Urination:
- Urinating more or less frequently than usual
- Foamy or bubbly urine (indicating protein in urine)
- Blood in urine
- Difficulty urinating
Nausea and Vomiting: The buildup of waste products in the blood (uremia) can cause persistent nausea, loss of appetite, and a metallic taste in the mouth.
Sleep Problems: Toxin buildup, discomfort, and restless legs syndrome (common in CKD) can all interfere with sleep.
Itchy Skin: Mineral imbalances and waste buildup can cause persistent, uncomfortable itching.
Muscle Cramps: Electrolyte imbalances, remarkably low calcium, and high phosphorus, can cause painful muscle cramps.
Cognitive Difficulties: Advanced kidney disease can affect concentration, memory, and mental clarity.
What Causes Chronic Kidney Disease?
Understanding the root causes of CKD is essential for prevention and management. In most cases, kidney disease results from other health conditions that strain the kidneys over time.
Leading Causes of Kidney Disease
Diabetes (Type 1 and Type 2): Diabetes is the #1 cause of kidney failure, responsible for approximately 45% of new cases. High blood sugar damages the small blood vessels in the kidneys, impairing their filtering ability. About 1 in 3 people with diabetes have CKD.
High Blood Pressure (Hypertension): Hypertension is the #2 cause of kidney failure. Elevated blood pressure damages blood vessels throughout the body, including in the kidneys. About 1 in 5 people with high blood pressure have CKD.
Glomerulonephritis: Inflammation of the kidney’s filtering units (glomeruli) can damage kidney function over time.
Polycystic Kidney Disease: This inherited condition causes fluid-filled cysts to grow in the kidneys, gradually replacing normal tissue and impairing function.
Other Causes:
- Prolonged use of certain medications (NSAIDs, some antibiotics)
- Urinary tract obstructions (kidney stones, enlarged prostate)
- Recurring kidney infections
- Autoimmune diseases (lupus)
- Heart disease
- Family history of kidney disease
CKD Complications: Why Comprehensive Care Matters
Chronic kidney disease doesn’t affect the kidneys alone. As kidney function declines, multiple organ systems are affected, necessitating comprehensive management.
Cardiovascular Disease
The leading cause of death in people with CKD is heart disease, not kidney failure. The connection between the kidneys and the heart is so strong that researchers refer to it as the “cardiorenal syndrome.” CKD increases the risk of:
- Heart attack
- Stroke
- Heart failure
- Irregular heartbeat (arrhythmias)
Anemia
As kidney function declines, the kidneys produce less erythropoietin (EPO), leading to reduced red blood cell production. Anemia affects:
- 14.9% of people with Stage 3, A1 diabetic CKD
- 57-61% of people with Stage 5, A3 CKD
Anemia causes fatigue, weakness, shortness of breath, and can worsen heart problems.
Bone and Mineral Disorders
Failing kidneys can’t properly balance calcium, phosphorus, and vitamin D, leading to:
- Weak, brittle bones
- Increased fracture risk
- Calcification of blood vessels and soft tissues
Fluid Retention
Impaired fluid regulation can cause swelling and may lead to hypertension and cardiac strain.
Electrolyte Imbalances
Disrupted potassium, sodium, and acid-base balance can cause muscle weakness, heart rhythm problems, and other complications.
Malnutrition
Loss of appetite, dietary restrictions, and metabolic changes can lead to weight loss and muscle wasting.
The 2024 KDIGO Guidelines: Modern CKD Management
The Kidney Disease: Improving Global Outcomes (KDIGO) organization released updated clinical practice guidelines in 2024, reflecting significant advances in CKD care. Key recommendations include:
Risk-Based Approach
Rather than focusing solely on eGFR numbers, the 2024 guidelines emphasize an individualized, risk-based approach to CKD management that considers:
- Overall kidney failure risk
- Cardiovascular risk
- Individual patient factors and preferences
- Quality of life
New Medication Recommendations
SGLT2 Inhibitors: These medications, initially developed for diabetes, have shown remarkable kidney-protective benefits. The guidelines now recommend SGLT2 inhibitors for many patients with CKD—with or without diabetes—when eGFR is greater than 20.
Statin Therapy: Cholesterol-lowering statins are recommended for adults aged 50 years and older with CKD due to their elevated cardiovascular risk.
Emphasis on Comprehensive Care
The guidelines stress the importance of:
- Early detection and referral to nephrology
- Multidisciplinary care teams, including dietitians
- Patient education and shared decision-making
- Conservative care is a valid option for some patients
Nutrition and Diet for Kidney Disease
One of the most critical aspects of CKD management is dietary modification. Because the kidneys can no longer efficiently filter waste and regulate electrolytes, what you eat directly impacts how well you feel and how quickly the disease progresses.
Key Dietary Considerations
Sodium (Salt):
- Recommendation: Less than 2,000 mg per day (approximately 5g of salt)
- Why: Excess sodium causes fluid retention, raises blood pressure, and strains the heart and kidneys
- Tips: Avoid processed foods, canned soups, and fast food; use herbs and spices instead of salt
Protein:
- Recommendation (Stages 3-5, not on dialysis): Approximately 0.8 g/kg body weight per day
- Why: High protein intake creates more waste for the kidneys to filter and may accelerate kidney damage
- Exception: Patients on dialysis may need more protein; elderly patients need a careful balance to prevent muscle wasting
Potassium:
- Recommendation: Individualized based on blood levels
- Why: Damaged kidneys can’t remove excess potassium, leading to dangerous heart rhythm problems
- High-potassium foods to limit: Bananas, oranges, potatoes, tomatoes, avocados
Phosphorus:
- Recommendation: Limit to 800-1,000 mg per day for advanced CKD
- Why: High phosphorus pulls calcium from bones, causing weakness and cardiovascular calcification
- High-phosphorus foods to limit: Dairy products, processed foods with phosphate additives, dark colas
Fluids:
- Recommendation: Varies by stage; may need restriction in advanced CKD
- Why: Failing kidneys can’t eliminate excess fluid, leading to swelling and breathing problems
The Shift Toward Plant-Based Eating
The 2024 KDIGO guidelines recommend that patients with CKD adopt healthy, diverse diets with greater consumption of plant-based foods and reduced intake of ultraprocessed foods. Research shows that plant-based diets can:
- Reduce protein load on the kidneys
- Decrease metabolic acidosis
- Lower inflammation
- Provide more bioavailable nutrients
- Slow CKD progression
How Home Care Can Help Clients with Kidney Disease
Living with chronic kidney disease presents daily challenges that can be overwhelming, especially for seniors managing multiple health conditions. Professional home care provides essential support that helps patients maintain their health, independence, and quality of life.
Preparing Kidney-Friendly Meals
Diet is one of the most critical—and most challenging—aspects of CKD management. Our caregivers can help by:
Meal Planning and Preparation:
- Preparing delicious, kidney-friendly meals that follow prescribed dietary restrictions
- Carefully limiting sodium, potassium, phosphorus, and protein as directed by the healthcare team
- Ensuring adequate caloric intake to prevent malnutrition (a common problem in CKD)
- Making meals appetizing despite restrictions—especially important when appetite is reduced
Grocery Shopping:
- Shopping for fresh, low-sodium, kidney-appropriate foods
- Reading nutrition labels to identify hidden sodium, phosphorus, and potassium
- Avoiding processed foods with phosphate additives
Hydration Management:
- Helping track fluid intake when restrictions are in place
- Providing measured amounts of fluids as prescribed
- Offering alternatives when the patient feels thirsty but has reached their limit
Medication Management
Patients with CKD often take multiple medications to manage kidney disease and its complications—sometimes 10 or more different pills each day. Our caregivers assist by:
Medication Reminders:
- Ensuring medications are taken at the correct times
- Helping organize pills using weekly pill organizers
- Reminding patients which medications to take with food
Pharmacy Coordination:
- Picking up prescription refills
- Communicating with pharmacies about medication questions
- Keeping track of when refills are needed
Monitoring for Side Effects:
- Observing for signs of adverse reactions
- Noting and reporting any concerns to family or healthcare providers
Transportation to Medical Appointments
CKD patients require frequent medical visits—especially as the disease progresses. Stage 4 and 5 patients may see their nephrologist every 1-3 months. Dialysis patients attend treatments 3-4 times per week. Our caregivers provide:
Safe, Reliable Transportation:
- Driving to nephrology appointments, dialysis treatments, and other medical visits
- Accompanying patients to ensure they don’t have to navigate healthcare settings alone
- Waiting during appointments and providing support afterward
Appointment Preparation:
- Helping patients prepare questions for their doctors
- Assisting with gathering relevant health information before visits
- Ensuring that patients bring necessary items (e.g., insurance cards, medication lists)
Physical Activity and Rehabilitation Support
Exercise is essential for patients with CKD—it helps control blood pressure, manage weight, maintain muscle mass, and improve mental health. Our caregivers can:
Encourage Safe Activity:
- Assist with range-of-motion exercises as recommended by physical therapists
- Accompany patients on walks
- Help with light stretching and movement throughout the day
- Ensure safety during physical activity
Prevent Deconditioning:
- Combat the tendency toward inactivity that often accompanies fatigue
- Support participation in appropriate activities that maintain strength and function
Domestic Duties and Home Safety
CKD-related fatigue, weakness, and shortness of breath make household tasks exhausting. Our caregivers help by:
Maintaining a Clean, Safe Home:
- Cleaning bathrooms, kitchens, and living areas
- Vacuuming, mopping, and sweeping floors
- Doing laundry and changing bed linens
- Organizing and decluttering
- Removing fall hazards
Creating a Comfortable Environment:
- Ensuring the home is conducive to rest and recovery
- Maintaining appropriate temperature and lighting
- Keeping essential items within easy reach
Personal Care Assistance
As CKD progresses, personal care tasks become increasingly complex. Our caregivers provide dignified, compassionate assistance with:
- Bathing and showering safely
- Dressing and grooming
- Toileting assistance
- Skin care (especially important given CKD-related itching)
- Mobility assistance
Emotional Support and Companionship
Living with a chronic disease takes an emotional toll. Depression and anxiety are common among CKD patients. Our caregivers offer:
Meaningful Companionship:
- Conversation and social interaction
- Engagement in enjoyable activities
- Emotional support during difficult times
- A consistent, caring presence
Reduced Isolation:
- Helping patients stay connected with family and friends
- Accompanying patients to social activities when able
- Providing mental stimulation through games, reading, and activities
Monitoring and Communication
Our caregivers serve as an essential link between patients and their healthcare team by:
Observing Changes:
- Monitoring for symptoms that may indicate worsening kidney function
- Noting changes in swelling, urination patterns, or mental status
- Tracking blood pressure and weight as directed
- Observing food and fluid intake
Communicating with Families:
- Keeping family members informed about their loved one’s condition
- Reporting concerns promptly
- Documenting care activities and observations
Home Dialysis Support
For patients who progress to kidney failure (Stage 5), dialysis becomes necessary to filter the blood. Many patients can receive dialysis at home—either peritoneal dialysis (PD) or home hemodialysis (HHD)—rather than traveling to a dialysis center three times per week.
Research shows that home dialysis offers several advantages:
- Improved quality of life compared to in-center hemodialysis
- Greater independence and flexibility
- Comparable or better outcomes in many cases
- Lower overall healthcare costs
Home care can support patients on home dialysis by:
- Assisting with supplies and equipment organization
- Helping maintain a clean treatment environment
- Providing support during and after dialysis sessions
- Offering companionship during treatment
- Assisting with other daily tasks so patients can focus on their dialysis routine
The Value of Early Intervention and Consistent Support
Research consistently shows that patients who receive comprehensive, coordinated care—including early nephrology referral and multidisciplinary support—have better outcomes. Value-based kidney care programs have demonstrated:
- 140% more optimal dialysis starts
- 50% higher home dialysis rates
- 41% higher transplant rates compared to national averages
These outcomes underscore the importance of consistent support throughout the CKD trajectory—precisely what professional home care provides.
