Sign and symptoms of renal failure


Symptoms may vary from person to person. A patient in early stage kidney
disease may not feel sick or notice symptoms as they occur  when the kidney fails to properly, waste
accumulates in the blood and the body a condition called azotemia very low
level of azotemia may produce few or no 
symptoms. If the disease progresses symptoms may be noticeable(if the
failure is of sufficient degree to cause symptoms). Renal failure accompanied
by noticeable symptoms is termed ureamia (Grinsted, 2005). Symptoms of renal or
kidney failure include the following.

i.                    
High
level of urea in the blood which may result in: Vornittina, frequent urination
or in greater amounts than usual, dark coloured urine, blood in the urine, pressure
or difficulty urinating, nausea, weight loss diarrhea which may lead to
dehydration.
ii.                  
A buildup
of phosphate in the blood that the diseased kidney cannot filter out may cause:
itching, bone diarrhea, non-union in broken bones, muscle cramps(caused by low
level of calcium which can be associated with hyperphosphotermia)
iii.                 
A buildup
of potassium in the blood that diseased kidneys cannot filter out called
hyperkalemia) may cause: Abnormal heart rhythms, muscle paralysis
iv.               
Failure
of the kidney to remove excess fluid may result in: Swelling of the legs, ankles,
feet, face and hands, shortness of breath due to excess fluid in the lungs (may
also be caused by anaemia)
v.                 
Polycystic
kidney disease which causes large fluid filled cysts on the kidney and
sometimes the liver may result in: Pains in the back or side.
vi.               
Healthy
kidney produce the hormones erythropoietin that stimulates the bone marrow to
produce oxygen carrying red blood cells, as the kidney fail they produce less
erythropoietin resulting in decreased production of red blood cells, as a
result the blood carries less hemoglobin a condition known as anemia that can
result in: feeling tired, and/or week memory problem, difficulty concentrating,
dizziness, low blood pressure.
vii.              
Normally
protein are too large to pass through the kidney however they are able to pass
through when the glomeruli, are damaged, this does not cause symptoms until
extensive kidney damage has occurred after which symptoms include: foamy or
bubbly urine, swelling in the hands, feet, abdomen or face. Other symptoms
include: Appetite loss, a bad taste in the mouth, difficulty sleeping,
darkening of the skin excess protein in the blood with high dose penicillin,
renal failure patients, may experience seizures (Angen, 2009)
