What is the normal function of the kidneys?
Your kidneys work to filter out water and waste from your blood stream. The wastes are concentrated then sent to your bladder to be stored as urine. Your kidney’s also work to regulate your blood pressure.
Why is kidney disease known as the Silent Killer?
Most people do not experience symptoms of kidney disease until damage has already been done. Kidney disease is most often referred to as Chronic Kidney Disease which results from a pre-existing condition that contributes to damaging the kidneys. Some pre-existing conditions include Diabetes, Nephritis, Kidney Stones, and Polycystic Kidney Disease. Acute Kidney Disease, resulting from trauma or injury, is reversible, but requires immediate treatment.
What is Chronic Kidney Disease? What does this mean to the function of the kidneys?
Chronic Kidney Disease happens over several years and slowly damages the kidneys, effectively “killing” them. Chronic Kidney Disease is broken down into 5 Stages determined by the percentage of remaining function.
Stage 1 – Kidney function is more than 90%
- Slight impairment, normal blood values
- Treatment includes a healthy diet and exercise.
Stage 2 – Kidney function is between 60 – 89%
- Worsening impairment, slightly elevated Creatinine and Urea in the blood
- No symptoms
Stage 3 – Kidney function is between 30 – 59%
- Symptoms appear including fatigue, poor appetite and itching
- Treatment is aimed at stopping or slowing further decline in kidney function.
- Diagnosed by elevated Creatinine and Urea levels of the blood with Anemia
Stage 4 – Kidney function is between 15 – 29%
- Symptoms worsen, Creatinine * and Urea * are further elevated
- Dialysis is prescribed as the main form of treatment due to the kidneys inability to function enough to keep the patient alive.
Stage 5 – Kidney function is less than 15%
- Symptoms worsen to include poor sleeping, difficulty breathing, itching, and vomiting, high blood levels of Creatinine and Urea
- Dialysis is prescribed and transplantation is considered
What is dialysis? What is the difference between Hemodialysis and Peritoneal Dialysis?
Dialysis is an artificial method of cleansing the blood of waste. It is a life long treatment.
Hemodialysis uses an artificial kidney machine to collect the blood from the body and cleanse it of the wastes. The cleansed blood is then returned to the patient. Hemodialysis is done in a dialysis unit, up to 5 hours per day, 3 times per week.
Peritoneal dialysis works to cleanse the blood inside the patient’s body. The abdomen is filled with a clear, dialysis fluid allowing for the peritoneum** to act as the artificial kidney. Cleansing of the blood is continuous with the clear fluid changed regularly through the day. Peritoneal dialysis can be performed in the home with the aid of a community nurse.
So why is Chronic Kidney Disease known as the Silent Killer?
Since Chronic Kidney Disease can damage the kidneys for years before the patient shows signs and symptoms, early detection is key. If you are at risk of developing kidney disease due to a pre-existing condition or family history, it is extremely important to watch for the following symptoms:
- High blood pressure
- Puffy eyes, hands and feet
- Urine that is cloudy, tea-coloured or bloody
- Protein in the urine
- Foaming of the urine
- Frequency of urination, especially during the night
- Fatigue
- Poor appetite or complete loss of appetite
- Itching that is generalized and persistent
Now that you know why Chronic Kidney Disease is known as the Silent Killer, what will you do to protect yourself and your kidneys?
*Creatinine & Urea – elements in the blood that are indicators of kidney function
**Peritoneum – the lining of the abdominal cavity
