Does symptom distress negatively affect quality of life in hemodialysis patients?
Symptom distress refers to the physical and emotional discomfort caused by symptoms of kidney disease and dialysis treatment. In hemodialysis patients, common distressing symptoms include post-dialysis fatigue, itching (pruritus), anxiety, and depression. Research consistently shows that these symptoms are linked to worse quality of life, affecting daily activities, sleep, and mental health.
What the research says
A 2022 study found that longer dialysis recovery time (DRT) — a measure of post-dialysis fatigue — was significantly associated with worse scores on the kidney disease quality of life questionnaire, including symptom burden, effects of kidney disease, and physical health 9. Another study reported that 55% of patients had a DRT over 4 hours, highlighting how common this distressing symptom is 9.
Chronic kidney disease-associated pruritus (itching) also takes a toll. A 2026 prospective study followed 747 hemodialysis patients and found that 52% developed moderate-to-severe itching over 18 months, and this symptom was linked to worse patient-reported outcomes for sleep, fatigue, depression, and general health 10.
Psychological distress is another key factor. A 2025 study of 65 maintenance hemodialysis patients found that 55% had anxiety symptoms and 51% had depressive symptoms, and both were independently associated with poor sleep quality 11. Poor sleep further reduces quality of life.
Nutrition education may help improve quality of life. A meta-analysis of 44 studies showed that nutrition education significantly improved health-related quality of life in dialysis patients (SMD = 1.43) 6. This suggests that addressing symptom distress through education and support can make a meaningful difference.
What to ask your doctor
- How can I track my symptom distress, such as fatigue after dialysis or itching, to discuss with my care team?
- Are there treatments or adjustments to my dialysis prescription that could reduce post-dialysis fatigue?
- What options are available for managing itching related to kidney disease?
- Could a referral to a mental health professional help with anxiety or depression affecting my sleep and quality of life?
- Would a nutrition education program be beneficial for improving my overall well-being?
