What are the symptoms of kidney failure?
Many different symptoms can occur during kidney failure. Usually someone with kidney failure will have a few symptoms of the disease, though sometimes none are present. Possible symptoms include:

a reduced amount of urine
swelling of your legs, ankles, and feet from retention of fluids caused by the failure of your kidneys to eliminate water waste
unexplained shortness of breath
excessive drowsiness or fatigue
persistent nausea
confusion
pain or pressure in your chest
seizures
coma

CAUSES
What causes kidney failure?
People who are most at risk for kidney failure usually have one or more of the following causes:
Loss of blood flow to the kidneys
A sudden loss of blood flow to your kidneys can prompt kidney failure. Some diseases and conditions that cause loss of blood flow to the kidneys include:

a heart attack
heart disease
scarring of the liver or liver failure
dehydration
a severe burn
an allergic reaction
a severe infection, such as sepsis

High blood pressure and anti-inflammatory medications can also limit blood flow.
Urine elimination problems
When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways. These include prostate (most common type in men), colon, cervical, and bladder cancers.
Other conditions can interfere with urination and possibly lead to kidney failure, including:

kidney stones
an enlarged prostate
blood clots within your urinary tract
damage to the nerves that control your bladder
