There are certain formula available on the market which are low protein formula prepared for renal patients, still, before incorporating them into your diet program, you will have to consult your doctor or dietician, or you would face worse consequences.

Restrict the intake of foods containing potassium:

• Potassium ions are discharged mainly via kidney, in patients who suffer from initial renal failure elevated concentration of potassium in the blood is rather rare, still, once the renal failure enters its terminal phase, owing to failure for potassium to be effectively discharged outside the body, accumulated in the body over time would result in elevated concentration of potassium in the blood, and that brining about arrhythmia, eventually lethal.
• Foods containing higher potassium are chiefly vegetable and fruits, such as: carrots, celery, lettuce, water spinach, spinach, amaranth, champignon, potato, hard persimmon, pomegranate, musk melon, banana, longan, grape and liu din tangerine.
• By poaching vegetables in the water for 3~5 minutes, pick up and stir in oil or fry, the potassium content can be reduced. Also note that the concentration of potassium in the soup is rather high so refrain from drinking much vegetable-based soup.
• Both Liu din tangerine juice and unsalted sauce contain elevated concentration of potassium and to which renal patient ought to keep a wide berth.
  Restrict the intake of foods containing phosphorus:
• The main source of phosphorus into the body is food, the main channel for discharge of same is kidney. A renal failure patient will leave phosphates piling up in the body, and that bringing down the level of calcium in the blood, resulting eventually in hyperparathyroidism, and this gives occasion to skeleton ailments, soreness, so there is a need to restrict the intake of phosphorus in the diet.
• Without prejudicing the principle of restraint of protein intake, refrain from inputting foods rich in phosphorus contents such as: leaven, entrails, full cereals (including unpolished rice grain, germ ice, full wheat bread), peas, nuts, egg yolk, milks, chocolates, etc…
• Ingest drugs that will combine with phosphates so as to reduce the intake of phosphorus in the food, not however, that such drugs must be chewed into tidbits with food and both intermixed perfectly to see to it that such an effect comes by.

Notes on the drugs and else:

• See to it that drugs which are essentially discharged by the kidney must be prescribed in such posology that they would not pile up in the body, especially with respect to blood sugar lowering agents and anti-arrhythmia agents.
• Avoid or decrease the use of analgesics and antibiotics.
• Avoid ingesting herbal medicines with grandiloquent efficacy or of ambiguous origination.
• Followup periodically in a renal service.
• Properly put your blood sugar and blood pressure under control.
