Currently, there is a growing awareness surrounding kidney health. If the kidneys fail to filter the waste effectively, a situation known as kidney failure arises. When the kidneys cannot properly filter the blood, wastes accumulate in them, which upsets the balance of the chemical constituents.

Kidney failure, whether acute or chronic, varies in length, onset, and reversibility. Kidney function rapidly declines as a result of acute renal failure, which happens unexpectedly and is frequently caused by an injury or infection. Usually, it can be reversed with quick medical attention. On the other hand, chronic kidney failure occurs gradually over months or years and is frequently brought on by diseases like diabetes or high blood pressure. As irreversible damage builds up, renal function eventually declines permanently.

What is the Difference Between Acute and Chronic Kidney Failure?

Chronic kidney disease (CKD) and acute kidney injury (AKI) vary in several important ways:

Acute Kidney Failure

Chronic Kidney Failure

Usually brought on by a medication, disease, or trauma

Usually brought on by a long-term sickness

Kidney function declines rapidly.

Kidney function declines gradually

The symptoms appear suddenly and may be quite serious.

Until the damage is severe, symptoms might not show up.

The goal of the treatment is to address the underlying reason.

The goal of the treatment is to manage the underlying problem.

Often reversible with prompt treatment.

Irreversible, focuses on slowing further deterioration.


Symptoms and Causes of Acute Kidney Failure

Acute kidney failure signs and indicators might include:

Causes of Acute Kidney Failure Include:

Symptoms and Causes of Chronic Kidney Failure

In cases where kidney damage advances slowly, signs and symptoms of chronic kidney failure gradually appear. An accumulation of fluid, bodily waste, or electrolyte imbalances can result from renal failure. 

Depending on the extent, kidney function loss might result in:

When a sickness or disease affects kidney function, kidney damage worsens over a period of months or years, leading to chronic kidney disease. 

The following diseases and conditions can result in chronic kidney disease:

Treatment of Acute Kidney Failure

Acute kidney failure usually requires hospitalization for treatment. The duration of your hospital stay depends on the cause of your acute kidney damage and the speed at which your kidneys heal. In certain situations, you may be able to recuperate at home.

The treatment of acute kidney failure focuses on addressing the underlying cause, supporting kidney function, and preventing complications. The main aspects of treatment include:

You might not need to follow a particular diet once your kidneys heal, but eating healthily is still crucial.

Treatment of Chronic Kidney Failure

While there is no cure for chronic kidney disease (CKD), you can live a much longer life with healthy, working Kidneys.


Some tips to keep kidney problems at bay. It will be imperative for you to maintain an optimum weight, exercise daily, drink enough water, eat a nutritious diet, and cut down on alcohol, smoking, and drugs. Check the blood pressure, blood sugar, and cholesterol levels as suggested by the doctor. Do not take any medication without the knowledge of the doctor and go for regular health check-ups. Follow these tips and you will surely be able to improve your quality of life.

FAQs on Difference Between Acute and Chronic Kidney Failure

Q. Can CKD be cured?

Chronic kidney failure is generally irreversible and incurable, but its progression can be slowed or managed through lifestyle changes, medications, and, in advanced cases, kidney replacement therapy like dialysis or kidney transplantation.

Q. Can CKD go back to normal?

Although chronic kidney disease (CKD) is usually irreversible, it can be slowed down in its course and further decline may be avoided with early identification and appropriate care. Although returning of kidney function to normal is rare, taking preventative actions can improve kidney health in general and lessen problems.

Q. What are the 3 stages of acute kidney failure?

Acute kidney failure (AKI) is typically classified into three stages:
  • Stage 1: Slight increase in serum creatinine and potential urine output changes.
  • Stage 2: Moderate increase in serum creatinine, often with decreased urine output.
  • Stage 3: Severe increase in serum creatinine or initiation of renal replacement therapy, indicating the most severe form of AKI.

Q. How is AKI diagnosed?

Acute kidney failure is diagnosed through clinical evaluation, blood tests measuring serum creatinine and BUN, urine tests for abnormalities, and imaging studies like ultrasound or CT scans to assess kidney structure and function. Identification of underlying causes and functional assessments further contribute to a comprehensive diagnosis.

Q. What is stage 5 chronic kidney disease?

When a person has End-Stage Renal Disease (ESRD) and their glomerular filtration rate (GFR) is less than 15 ml/min, they require dialysis or kidney transplantation as a means of survival. This is known as Stage 5 Chronic Kidney Disease (CKD). Severe symptoms indicate a potentially fatal illness in the absence of treatment.
