Chronic Renal Failure

Chronic renal failure develops over months and years. Chronic kidney disease is particularly dangerous, because you may not have any symptoms until considerable, often irreparable, kidney damage has been done. Diabetes (types 1 and 2) and high blood pressure are the most common causes of chronic kidney disease (CKD). Other causes are Immune system conditions, such as lupus, and chronic viral illnesses such as HIV/AIDS, hepatitis B, and hepatitis C.

Symptoms for Chronic kidney disease
  • Nausea and vomiting
  • Passing only small amounts of urine
  • Swelling, particularly of the ankles, and puffiness around the eyes
  • Unpleasant taste in the mouth and urine-like odour to the breath
  • Persistent fatigue or shortness of breath
  • Loss of appetite
  • Increasingly higher blood pressure
  • Muscle cramps, especially in the legs
  • Pale skin
  • Excessively dry, itchy skin
  • In children: increased fatigue and sleepiness, decrease in appetite, and poor growth

Dietary Guidelines
Salt (or sodium) is a major cause of CKD, high blood pressure and heart disease. High salt intake causes fluid retention. Low-salt substitutes are no good either, since they contain high levels of potassium
A low-protein diet slows disease progression and avoids build-up of excess urea. Protein is however essential for growth, muscle building and tissue repair. So consume enough protein to stay healthy
Potassium levels can be high in severe renal failure or for those on dialysis. Very high levels are dangerous and can cause cardiac arrest. Restrict intake only after consulting your dietician and checking your potassium level. This is necessary because potassium is present in many healthy foods
Phosphorus levels must also be controlled. Excess phosphorus can cause total kidney failure as well as bone disease and heart ailments. Since most foods contain phosphorus, it's necessary to take a medication called phosphate binder. When you consume phosphate binders like sevelamer carbonate during or immediately after meals, it binds like a magnet to the phosphorus in your food. This prevents phosphorus from being absorbed by your body
Calcium is another concern for kidney patients, causing serious bone disease in later years if not controlled
Fluid intake must also be monitored. If not on dialysis, however, do not restrict fluids unless there is a fluid overload problem. Drink water only when you are thirsty. If fluid retention is a problem, limit salt intake. Fluid intake cannot be controlled if you consume too much salt – you will keep feeling thirsty
Healthy eating controls blood pressure, weight, cholesterol and blood sugar levels, slowing the progression of kidney disease. While diet control is critical, the portion size also matters. If you eat in excess, the nutritional value changes considerably
Cigarettes and alcohol must also be avoided or reduced. If you follow these guidelines strictly, your life will never be completely knocked down by CKD.
