Chronic Renal Failure (CRF) is the advanced result of various Chronic Kidney Diseases. As the renal function declines, the uremic toxins and wastes will accumulate in their body, which can destroy the internal environment balance of body and damage multiple organs. Therefore, the patients will have a series of complications.
1. Gastrointestinal tract diseases
The patients with Chronic Renal Failure often have gastrointestinal tract
symptoms such as poor appetite, nausea, vomit, nausea and so on. In addition,
some patients even have mucosa ulceration and erosion in their gastrointestinal
tract, which can cause gastrointestinal haemorrhage.
2. Renal anemia
The patients with Chronic Renal Failure often have anemia, which is called
renal anemia. After the patients enter End Stage Renal Failure, nearly all
patients will have anemia. It is mainly caused by the following factors.
A: The patients usually have poor appetite, nausea and vomit so the body can
not get sufficient raw materials of blood.
B: The uremic toxins can restrain the blood marrow thus declining the
production of red blood cells.
C: The patients often have gastrointestinal hemorrhage, which can cause red
blood cells to lose.
D: As the renal function declines, the kidneys can not produce enough
hemopoietin. It is the main cause of renal anemia.
The patients with renal anemia often have dizziness, palpitation, short
breath, fatigue and so on.
3. Nervous system disorders
A: Central nervous system disorder: the patients often are slow in reaction,
cold expression, and somnolence and even have abalienation, epilepsia and
B: Peripheral nervous system: the patients often have abnormal feelings in
their limbs. What is worse, some patients may have restless legs syndrome.
Besides the above complications, the patients often have bone diseases, skin
diseases, and water and electrolyte disturbance and so on. Therefore, the
patients with Chronic Renal Failure should receive early treatment so as to
prevent its complications.
