Kidney failure is a serious impairment of kidney function, when the ability to function is only below 15% compared to normal. This is a dangerous stage of kidney disease, greatly affecting the health and quality of life of patients. In many cases, kidney failure progresses silently over many years without obvious symptoms. Some people only accidentally detect the disease when going for health check-ups or getting blood and urine tests.
However, there are also cases of acute kidney failure that appear quickly in just a few days, often related to severe infection or serious damage in the body. At that time, not only the kidneys but also many other organs may be affected.
One of the less noticeable signs of kidney failure is prolonged skin itching. Many people often think this is just allergies, dry skin, or due to weather changes, so they are subjective and do not go for health check-ups. In fact, persistent systemic itching is sometimes directly related to impaired kidney function. In patients with chronic kidney disease, the body cannot effectively eliminate harmful substances, causing toxins to accumulate in the blood. At the same time, mineral disorders and increased inflammatory reactions also contribute to uncomfortable itching.
A noteworthy point is that itching due to kidney failure may not be accompanied by rash or obvious skin damage. However, patients still feel severe itching, especially at night, causing insomnia, fatigue and greatly affecting daily activities. For people with late-stage kidney failure, this symptom can last continuously and significantly reduce the quality of life.
Experts recommend that if the itching persists for many weeks, spreads throughout the body or does not improve even after taking regular medication, patients should go to the doctor early to check on kidney function. Early detection of the disease is very important, helping to control the progression of kidney failure, reduce the risk of complications and improve long-term treatment effectiveness.
