What causes acute kidney failure?

Answer 1

Fluids and toxins begin to accumulate in the bloodstream. As fluids build up in the bloodstream, the patient with acute kidney failure may become puffy and swollen (edematous) in the face, hands, and feet. Their blood pressure typically begins to rise

Answer 2

Here are a few of the causes:

Bacterial and viral diseases. Strep, for example, can attack and scar the kidneys.

High blood pressure (often part of the complications of Diabetes).

Limited blood flow (due to heart or artery disease or severe blood loss)

Severe dehydration.

Injury.

Certain abused drugs including alcohol (but liver damage is usually present first).

Blockages including kidney stones.

The kidneys typically do not ever gain back the function that they have lost due to any of these causes. They do not heal. The body has only a very small ability to use other systems to do the kidney's functions (the skin can eliminate some toxins and excess salts, for example) so that a person in acute kidney failure will become dependent on dialysis or require a transplant if renal function falls below around 15% or so of normal.

Answer 3

Acute kidney failure can be caused by conditions that affect blood flow to the kidneys (such as dehydration, blood loss, or sepsis), damage to the kidneys (such as from injury, medication toxicity, or infection), or obstruction of the urinary tract (such as from kidney stones or enlarged prostate). Other factors like severe infection, autoimmune diseases, or certain medications can also contribute to acute kidney failure.

Answer 4

Acute renal failure is caused by damage from certain medicines and poisons. It can also be caused by a drop in blood flow to the kidneys and blockage that stops the flow of urine.
