• Dialysis inadequacy related accumulation of uremic toxin.
• Anemia, iron deficiency.
• Sweat gland hypofunction.
• Side effects of medications and allergies, such as heparin, disinfecting agents and tape allergies.
• Allergy to artificial kidney disinfectant or material.

Treatment

• Adequate dialysis, increased blood flow, dialysis duration, and artificial kidney size.
• Low-phosphorus diets and phosphor-binding drugs are used to reduce blood phosphorus to improve itching, while active vitamin D can low down the levels of parathyroid hormone.
• The usage of erythropoietin has been shown to improve anemia, or itching.
