Your kidneys are a pair of organs situated within the region of your lower back. The kidneys filter your blood and take away toxins from your body. These toxins move to your bladder and are eliminated via the urine. 

Kidneys lose their ability to efficiently filter waste from your blood in case of inflammation or damage. Many factors may interfere with the performance of the kidney and affect its health such as:

·         Certain acute and chronic diseases

·         Toxic exposure to environmental pollutants or sure medications

·         Severe dehydration

·         Insufficient blood flow to the kidneys

·         kidney trauma

If your kidneys aren’t working properly, toxins can accumulate in the body which might be life-threatening if left untreated.

Types of Kidney Failure

Acute kidney failure occurs suddenly when the kidneys suddenly stop working while chronic nephritis happens over time.

The 5 types of kidney failure include:

Acute prerenal kidney failure 

• Cause -
  
•  Insufficient blood flow to the kidneys.
• The kidneys can’t filter toxins from the blood without enough blood flow.

Prognosis

Can usually be cured once the cause of the reduced blood flow is determined.

Acute intrinsic kidney failure -

Cause -

•         Direct trauma to the kidneys, such as physical impact or an accident.
• Toxin overload and ischemia due to lack of oxygen to the kidneys.

Prognosis 

lose of the ability to function.

Chronic prerenal kidney failure -

Cause

There isn’t enough blood flowing to the kidneys for an extended period.

Prognosis 

The kidneys begin to shrink and lose the ability to function.

Chronic intrinsic kidney failure -

Causes 

  Long-term damage to the kidneys due to intrinsic kidney disease due to

  Trauma to the kidneys

Prognosis

Eventual kidney damage

Chronic post-renal kidney 

Cause 

Long-term blockage of the urinary tract prevents urination.

Prognosis

Pressure and eventual kidney damage failure.
