Where Does Itching Occur with Kidney Disease?


Itching, medically known as pruritus, is a common symptom of kidney disease. It affects approximately one-third of people with chronic kidney disease (CKD) and up to 80% of those on dialysis. This itching can be a significant source of discomfort and can ultimately lead to complications if left untreated. The purpose of this article is to help the audience understand and manage skin itching caused by kidney disease.

Understanding how kidney disease affects skin

Kidney disease affects various systems in the body, including the skin. The kidneys are responsible for filtering waste products and excess fluids from the body. When they are not working correctly, toxins can accumulate in the bloodstream, leading to skin complications.

Furthermore, the kidneys play a vital role in maintaining healthy skin. They help regulate the body’s water balance, which is critical for hydration. They also help regulate the body’s salt balance, which can affect the skin’s moisture and texture. Inadequate kidney function can lead to a buildup of waste products, which can lead to skin itching.

Common itchy skin conditions associated with kidney disease

There are several skin conditions associated with kidney disease that can cause itching. One of the most common is dry skin, which can occur due to dehydration and inadequate kidney function. Another common skin condition is eczema, which can be exacerbated by the buildup of toxins in the bloodstream. Uremic pruritus, or persistent itching associated with advanced CKD or dialysis, is also a common skin condition in people with kidney disease.

The exact causes of these skin conditions are not entirely understood, but they are thought to be related to the buildup of toxins and inflammation in the body associated with kidney disease.

Inflammation is the body’s natural response to disease and injury. However, chronic inflammation can cause additional health problems, including itching. Inflammation associated with kidney disease can cause skin itching, as well as pain and discomfort.

Inflammation can also lead to oxidative stress, which can cause further damage to the skin and contribute to itchiness. If left untreated, inflammation can lead to skin complications, so it is essential to manage it appropriately.

How to manage skin itching when you have kidney disease

Managing skin itching can be difficult for people with kidney disease. There are several steps you can take to control itching and prevent complications, including:

  • Avoiding triggers- such as hot showers and baths, fragranced products, and fabrics that can exacerbate itching
  • Taking care of the skin- keeping the skin clean and moist by using fragrance-free and hypoallergenic products, avoiding hot water, and not scratching the skin
  • Maintaining a healthy lifestyle- eating a healthy diet, staying hydrated, exercising regularly, and getting enough sleep

It is essential to seek medical advice if symptoms persist or worsen. There are several treatment options available to help manage skin itching, including topical creams and lotions.

Topical treatments for itchy skin caused by kidney disease

Topical treatments are a common way to manage skin itching associated with kidney disease. There are several different treatment options available, including:

  • Moisturizers- these can help relieve dry skin and reduce itching
  • Corticosteroids- these can help relieve itching and reduce inflammation
  • Antihistamines- these can help reduce itching by blocking the action of histamines in the body
  • Topical calcineurin inhibitors- these can help reduce inflammation and itching, especially in people with eczema

It is essential to talk to your doctor about the most effective treatment option for your individual needs. Your doctor can help you weigh the benefits and risks of different treatments and find one that is right for you.

Lifestyle changes that can help reduce itching from kidney disease

In addition to topical treatments, making certain lifestyle changes can help reduce itching and discomfort associated with kidney disease, including:

  • Maintaining a healthy diet- eating a healthy, balanced diet can help improve kidney function and reduce inflammation
  • Staying hydrated- drinking plenty of water can help improve kidney function and prevent dehydration, which can exacerbate dry skin
  • Exercising regularly- regular exercise can help improve overall health and reduce inflammation
  • Getting enough sleep- getting enough restful sleep can help improve overall health and reduce inflammation

When to see a doctor for kidney disease-related itching

If you are experiencing itching related to kidney disease, it is essential to seek medical attention promptly. Uncontrolled itching can lead to skin complications, such as infections and rashes, that can be challenging to manage and treat.

You should also seek medical attention if your itching is accompanied by other symptoms, such as swelling, pain, or a rash. These symptoms could be a sign of a more severe underlying condition and require medical intervention.


Itching is a common symptom of kidney disease that can be frustrating and uncomfortable. Managing skin itching associated with kidney disease requires a multifaceted approach that may involve topical treatments, lifestyle changes, and medical interventions. If you are experiencing skin itching, it is essential to seek medical attention promptly to prevent complications and ensure the most effective treatment.
