stage 3 kidney disease life expectancy: Stage 3 Kidney Disease Life Expectancy

What is Kidney Disease?

The kidneys as an organ are small bean-shaped but they filter the waste from your body and help maintain the overall health. Within one hour, they filter your blood around 12 times. The unwanted toxins and the excess water are disposed of in the form of urine. When your body fails to filter the wastes properly, you surely have kidney disease. But the question is, what type of kidney disease do you have and what stage are you in?

Types of Kidney Diseases

Acute Kidney Disease or Injury

AKD or AKI occurs when your kidneys experience any sudden harm or injury. This type of kidney disease is short term and if not treated, they turn to chronic kidney disease. The reasons for AKD includes:

  • Sudden exposure of your kidneys to excessive alcohol abuse, drugs, elements or severe infection.
  • Moreover, if you are having a kidney stone or enlarged prostate, you may suffer from acute kidney disease injury.
  • People with Chronic Kidney Disease have higher chances of suffering through AKI.

Chronic Kidney Disease (CKD)

With the passage of time, the kidneys become vulnerable to kidney infections and diseases. If not diagnosed or detected, the condition gets worse and this is called Chronic Kidney Disease or CKD. There are many causes of CKD, the key reasons are:

  • The blood vessels or cells are damaged due to diabetes or high blood pressure
  • The kidney is attacked by any viral disease or by your immune system
  • Polycystic disease of the kidney, when the kidney is attacked by the cysts
  • Reflux nephropathy does severe damage to the kidneys as the urine flows backward to your kidneys

But it is important to understand that Chronic Kidney Disease and Chronic Kidney Failure are not the same things. And it is only in stage 5 when kidney failure usually occurs. If you start your treatment right away and start taking proper kidney supplements according to your need, kidney failure can be avoided. Thus the percentage of people that might have kidney failure in stage 3 is very low i.e. the ratio is 1:5 (that means only one in every five patient suffers from kidney failure in stage 3).

Kidney Disease Risk Factors

  • High Blood Pressure
  • Diabetes
  • Obesity
  • Heart problems
  • Age over 60 years
  • Inherited kidney disease
  • Smoking
  • Acute Kidney Disease

Stages of Kidney Disease

Your kidney will not fail you at one go. If you’re involved in heavy substance abuse and don’t lead a healthy lifestyle, your kidney will slowly fall victim to various issues. It will fight with all its strength to 5 stages over the years. You need to understand the different stages of chronic kidney disease. The available best method for determining kidney diseases is using GFR data (Glomerular Filtration Rate).

What is GFR?

It is a number or in fact, a benchmark set for doctors to determine which stage of kidney disease you are in. This is determined using a formula, which includes your age, gender and the amount of creatinine serum level in your body. The amount of waste material that is released from your muscle activities are measured by creatinine.

Stage Determination

How to understand what GFR indicates which stage of kidney disease?

  • When you see your GFR level is greater or equal to 90 milliliters per minute you are in Stage 1. This means your kidneys are functioning properly.
  • Stage 2 is where your CKD (Chronic Kidney Disease) strikes. You will have your GFR level within a range of 60-89 ml/ min. This condition is termed as Mild CKD and Stage2 or Pre-stage 3 kidney disease.
  • For a patient with stage 4, the GFR level would be within 15 and 30. This is a severe CKD condition for anyone.
  • Any GFR level less than 15 is THE END stage or Stage 5 for a CKD infected person.

What is Stage 3 kidney disease?

Stage 3 kidney disease is when the renal problems symptoms and signs show up. You would often see people experiencing kidney pain and rushing to doctors. That’s when the preliminary stage is identified by the doctors. Now that you find yourself in stage 3 kidney disease, the kidney is damaged moderately. This stage can be divided into two sub-segments based on Glomerular Filtration Rate (GFR). Firstly, a patient with GFR range 45 to 59 milliliter per minute is considered as Stage 3A. For people who are below 44 to 30 milliliter is termed as Stage 3B.


In order for you to move to post stage 3, you need to meet many criteria. However, this is a stage which is reversible; in fact, you can improve your kidney conditions that we have explained later in this article. This is possible only if the complications aren’t that severe that you will know after going through the different stages of kidney disease.

At least once in everyone’s lifetime, people would experience flank pain but if it is regular do not wait to visit your nearby doctor, you never know you might be in a severe medical condition.

Mouth Tastes like metal

Uremia is a waste that is found in your blood. This makes your tongue taste like metal and causes bad breath. People who are infected with kidney diseases notice this type of problems.
