Symptoms of Advanced Kidney Disease Requiring Dialysis or Transplantation
Patients with advanced chronic kidney disease (CKD) requiring dialysis or transplantation experience a high burden of multiple physical and psychosocial symptoms, with fatigue being the most common (affecting approximately 70% of patients), followed by pain, pruritus (itching), constipation, and sleep disturbances. 1, 2
Most Common Physical Symptoms
The symptom burden in advanced kidney disease is substantial and multifaceted:
High-Prevalence Symptoms (>50% of patients):
- Fatigue/Tiredness: 70% of patients (most prevalent symptom) 1, 3, 4
- Pruritus (Itching): 55% prevalence, with 24.5% experiencing severe itching 1, 4
- Constipation: 53% of patients 4
- Anorexia (Loss of appetite): 49-56% prevalence, associated with malnutrition and poor quality of life 1, 4
Moderate-Prevalence Symptoms (30-50% of patients):
- Pain: 47% prevalence (most severe symptom when present) 2, 4
- Sleep disturbances: 60% prevalence, including insomnia and poor sleep quality 1, 4
- Anxiety: Approximately 40% of dialysis patients 2
- Dyspnea (Shortness of breath): 35% prevalence 4
- Nausea: 33% prevalence 4
- Restless legs syndrome: 30% prevalence, with 80% also experiencing periodic limb movements 1
Depression and Cognitive Symptoms:
- Depression: 27% prevalence, though rates vary by assessment method 4
- Cognitive impairment: Common in advanced stages 5, 6
Uremic Symptoms Indicating Need for Dialysis
The KDIGO guidelines specify that dialysis should be initiated when one or more of the following uremic symptoms are present 5, 6:
- Neurological signs attributable to uremia
- Pericarditis or serositis
- Medically resistant acid-base or electrolyte abnormalities
- Intractable pruritus
- Anorexia with progressive nutritional deterioration refractory to dietary intervention
- Nausea and vomiting attributable to kidney failure
- Cognitive impairment
These symptoms often occur when GFR falls between 5-10 mL/min/1.73 m², though timing should be individualized based on symptoms rather than GFR alone 5, 6.
Volume-Related Symptoms:
- Inability to control volume status or blood pressure
- Peripheral edema
- Dyspnea from fluid overload 5, 6
Additional Dialysis-Specific Symptoms
Patients on dialysis may experience additional treatment-related symptoms 2, 7:
- Muscle cramps during or after dialysis
- Hypotension during dialysis sessions
- Dry skin and dermatological issues
- Headaches
- Numbness and peripheral neuropathy
- Sexual dysfunction
Symptom Clustering and Impact
Symptoms typically occur in clusters rather than isolation, with one lead symptom accompanied by multiple secondary symptoms 7. This clustering significantly impacts:
- Health-related quality of life (HRQL)
- Ability to participate in work, family, and social activities
- Hospitalization rates (higher in the last month of life compared to other chronic illnesses) 1
- Overall life satisfaction 2
Critical Clinical Context
The KDIGO Controversies Conference emphasizes that the high level of disability and symptom burden in advanced CKD is not necessarily improved by dialysis initiation 1. Annual mortality exceeds 20% for patients on dialysis, and withdrawal from dialysis is a common cause of death worldwide, reflecting poor health-related quality of life 1.
Regular symptom assessment using validated tools (such as the Edmonton Symptom Assessment Scale-Renal or Dialysis Symptom Index) should be routine in renal programs to identify patients' most troublesome symptoms and redirect treatment toward patient-centered care 1.
Quality of Life Comparison
Quality of life measurements show significant impairment in dialysis patients compared to other CKD populations 3:
- Dialysis patients: SF-36 Mental Component Summary 45.7, Physical Component Summary 35.5
- Non-dialysis CKD patients: MCS 66.6, PCS 66.3
- Post-transplant patients: MCS 50.0, PCS 48.0
Several symptoms show significant improvement after transplantation (fatigue, depression, itching, poor mobility, poor sleep, dry mouth), suggesting these are directly attributable to kidney failure and dialysis 3.
