Failure – Causes and Symptoms
Healthy kidneys clean your
blood by removing excess fluid, minerals and
wastes. They also make hormones that keep your bones strong and your
blood healthy. But if the kidneys are damaged, they don't work
Harmful wastes can build up in your body. Your blood pressure
may rise. Your body may retain excess fluid and not make enough red
blood cells. This is called kidney failure.
Kidney failure means you have some decisions to make about your
treatment. You may choose to forgo treatment. If you choose to receive
treatment, your choices include hemodialysis, which requires a machine
used to filter your blood outside your body; peritoneal dialysis, which
uses the lining of your belly to filter your blood inside the body; and
kidney transplantation, in which a new kidney is placed in your body.
Each treatment has advantages and disadvantages. Your choice of
treatment will have a big impact on your day-to-day lifestyle, such as
being able to keep a job if you are working. You are the only one who
can decide what means most to you.
Kidneys are also the source of
erythropoietin in the body, a hormone
that stimulates the bone marrow to make red blood cells. Special cells
in the kidney monitor the oxygen concentration in blood. If oxygen
levels fall, erythropoietin levels rise and the body starts to
manufacture more red blood cells. After the kidneys filter blood, the
urine is excreted through the ureter, a thin tube that connects it to
the bladder. It is then stored in the bladder awaiting urination, when
the bladder sends the urine out of the body through the urethra.
Extremely low blood pressure: Severe bleeding, infection in the
bloodstream (sepsis), dehydration or shock can all lead to a drastic
drop in blood pressure that prevents an adequate amount of blood from
reaching your kidneys. Dangerously low blood pressure tends to follow
Glomerulonephritis is the inflammation and damage of the filtration
system of the kidneys and can cause kidney failure. Postinfectious
conditions and lupus are among the many causes of glomerulonephritis.
Ureter obstruction: Kidney stones in both of the tubes leading from
your kidneys to your bladder (ureters) — or in a single
ureter if only one kidney is functioning — can prevent the
passage of urine, as can tumors pushing in on the ureters.
Unfortunately, kidney failure can have very few symptoms to begin with.
As your kidney function declines, it will first be detected on blood
tests by your doctor. Most people don't feel any effects of kidney
failure during the early stages.
The patient is almost always out of breath because the blood is filled
with toxins, decreasing its oxygen carrying capacity. Also the lungs
could have water due to the water retention reducing its efficiency.
This lack of oxygen throughout the body causes dizziness and memory
As long as you are suffering
from acute renal failure, it is not a
life-threatening situation and can be cured when diagnosed in time. If
you ignore the acute renal failure symptoms and allow it to progress to
chronic renal failure, a total cure will be near impossible, even
leading to death in severe cases. If you have doubts that you suffer
from even one of the symptoms, visit your physician immediately. It
could be something totally different, but if it is connected with renal
failure, you could be saving a lot of problems in the future.
