Symptoms, Causes, and Types of Kidney Failure

Kidney failure

Kidneys filter your blood and remove toxins from your body. they send toxins to your bladder, which your body later removes toxins during urination.

Kidney failure happens when your kidneys lose the ability to sufficiently filter waste from your blood. So there are many factors that can interfere and plays the main role with your kidney health and function, such as:

  • Toxic exposure to environmental pollutants or certain medications.
  • Severe dehydration.
  • kidney trauma.
  • Overloaded toxins in the body if the kidneys can’t do their regular job.
  • Certain chronic diseases.

Symptoms of Kidney Failure

Usually, symptoms of kidneys failure can appear. Sometimes no symptoms are present, but there are some possible symptoms include:

  • Urination deficiency.
  • Swelling of the body particularly in the legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste.
  • Shortness of breath.
  • Excessive drowsiness, fatigue, or confusion.
  • Persistent nausea.
  • Feel pain or pressure in your chest.
  • Seizures or coma.

Early signs of kidney failure

Symptoms of early-stage kidneys failure may be difficult to pinpoint or appear. So they’re often hidden and hard to identify. If you experience early signs of kidney disease, you may notice these potentials symptoms:

  • Decreased urine.
  • Fluid retention that leads to swelling in the body.
  • Shortness of breath and feeling tired.

Causes of Kidney Failure

Kidney disease occurs in the result of several conditions or causes. Besides the cause typically also determines which type of kidney failure.

Usually, people who are most at risk have at least one of the following causes:


Decrease of blood flow to the kidneys

A sudden loss of blood flow to the kidneys can lead to kidney failure. Some conditions that cause a decrease in blood flow include:

  • A sudden heart attack or heart disease.
  • Liver failure.
  • Severe dehydration or burn.
  • An allergic reaction.
  • Severe infection (Sepsis).

High blood pressure and anti-inflammatory medications can prompt to limit blood flow.

Urine elimination problems

When the body can’t eliminate urine, toxins build up and stock in the kidneys. Besides, these accumulations can lead to some cancers tha can block the urine passageways, such as:

  • prostate (the most common type in men).
  • Colon.
  • Cervical.
  • Bladder.

Other conditions can interfere and lead to kidney failure, including:

  • Kidney stones.
  • An enlarged prostate.
  • Blood clots within the urinary tract.
  • Damage to the nerves that control the bladder.

Other causes

Some other things that may be the cause to kidney failure include:

  • An overload of toxins from heavy metals
  • Taking drugs and drinking alcohol.
  • Inflammation of blood vessels (vasculitis).
  • Lupus is an autoimmune disease that can cause inflammation of many body organs.
  • Glomerulonephritis is an inflammation of the small blood vessels of the kidneys.
  • Hemolytic uremic syndrome, which involves the breakdown of red blood cells after a bacterial infection, mostly in the intestine.
  • Multiple myeloma is a cancer of the plasma cells in your bone marrow.
  • Scleroderma, an autoimmune condition that affects your skin.
  • Thrombotic thrombocytopenic purpura is a disorder that causes blood clots in small vessels.
  • Chemotherapy drugs that treat cancer and some autoimmune diseases.
  • Certain antibiotics.
  • Uncontrolled diabetes.

5 Types of Kidney Failure


1. Acute prerenal kidney failure

Insufficient blood flow to the kidneys can prompt acute prerenal kidney failure. Therefore the kidneys can’t filter toxins from the blood without enough blood flow. So this type of kidney failure can usually be cured once the doctor determines the cause of loss blood flow.

2. Acute intrinsic kidney failure

Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical collision or an accident. Causes within also include toxin overload and ischemia, which is a decrease of oxygen to the kidneys.

Ischemia may occur when:

  • Severe bleeding.
  • Shock.
  • Renal blood vessel obstruction.
  • Glomerulonephritis.

3. Chronic prerenal kidney failure

When there isn’t enough blood flowing to the kidneys for an extended period of time, the kidneys begin to shrink and lose the ability to function regularly.

4. Chronic intrinsic kidney failure

This occurs when there’s long-term damage to the kidneys due to intrinsic kidney disease. Intrinsic kidney disease occurs from direct trauma to the kidneys, such as severe bleeding or a lack of oxygen to the kidneys..

5. Chronic post-renal kidney failure

Blockage of a long term to the urinary tract prompt to prevent urination. That leads to pressure and eventual kidney damage.
