Extremely itchy skin, or uremic pruritus, is a common symptom experienced by people living with chronic or advanced kidney disease. Patients undergoing dialysis are more likely to experience uremic pruritus than those who are not on dialysis.
The exact cause of uremic pruritus associated with kidney disease is not fully known. However, according to the National Kidney Foundation, there are several reasons why those with kidney disease may experience chronic itching, including:
- The body attacks itself, leading to inflammation and itching.
- Nerve issues may cause the skin to receive incorrect signals.
- When the kidneys are damaged, toxins and waste products can accumulate in the body.
- Shrinking sweat glands can result in very dry skin.
- The body may produce chemicals that trigger allergy symptoms, including itching.
- Hemodialysis treatments may not be long enough or may not completely clean the blood.
Uremic pruritus can be unbearable, and many patients scratch their skin to stop the constant itch. Scratching can lead to skin damage and infection. Persistent itching, without relief, can also impact quality of life, sleep, and mental health.
If you are living with advanced or chronic kidney disease and experiencing persistent itching, please inform your doctor. Your healthcare provider can help you manage symptoms by prescribing medications, making adjustments in your dialysis treatments, or recommending ultraviolet B (UVB) phototherapy.
