Why do People on Dialysis Experience Itching (Pruritus)

A majority of patients with Chronic Kidney Disease (CKD) who are on dialysis may experience itching (pruritus) at some point. Some persons may feel itchy all the time, while for others, it comes and goes. Itching may be worse during or just after dialysis treatment. What causes itching (pruritus) in people on dialysis?

Though there have been studies on this issue, there is no exact cause or solution for each person. Here are the most common causes of this problem:

▪ High level of phosphorus in the body.
This is a common cause of itching (pruritus) in people on dialysis, as dialysis does not effectively remove phosphorus. Therefore, a renal diet that limits high-phosphorus foods is suggested. Besides, taking phosphorus binders with every meal and snacks to help prevent or stop itching. Try to maintain a phosphorus level at 5.5 or less.

▪ Allergies
In some cases, itching occurs due to allergies. If a person notice pruritus at the beginning of dialysis, he or she may have an allergy to the blood tubing, dialyzer, the type of heparin being used or other elements associated with the treatment. Itching can also be a symptom of allergies to products patients use everyday.
