Can Kidney Failure Make You Itchy

Can Kidney Failure Make You ItchyItchy skin often attacks patient with kidney failure, and it can affect patient’s life quality obviously. Is itchy skin caused by kidney failure?

Kidney failure is a state that patient’s kidney function can not filter the wastes in blood adequately. As we know, kidney is an organ which is in charge of regulating our internal balance, so its damage will cause many disorders in our body, and itchy skin is one of its complications.

Thereby, why does itchy skin often appear in patient with kidney failure?

In fact, itchy skin can be caused by many problems which are caused by kidney failure.

Urea nitrogen:

When kidney lose its ability to adequately filter the wastes and toxins in blood, lots of them will accumulate in blood, and urea nitrogen is among them. The retention of urea nitrogen can stimulate patient’s sebaceous gland and sweat gland, which can cause drying, desquamation in patient’s skin, and this is a major reason of itchy skin.

Hyperfunctioning of parathyroid gland:

This is also a common cause of itchy skin in patient with kidney failure, which is often caused by high phosphorus in patient’s blood, which can cause the low amount of calcium in blood, and that can promote the excretion of parathyri.

While parathyrin can promote mast cells to excrete histamine, which can cause itching. Besides, the accumulation of calcium in skin is also a reason that can cause itchy skin.


Patient with kidney failure will need to take many medicines every day, and some medicines and medical machines, like ethylene oxide and dialysis machine, can also promote mast cells to excrete histamine, which will lead to itchy skin.
