Uremic patients can eat prunes, because the main component of prunes is fructose, which can provide the energy needed by the body, but it is recommended not to eat large amounts, because prunes contain a small amount of potassium ions, 100mg of prunes contain 140mg of potassium, such as a large amount of consumption can also appear high potassium. In the diet of uremic patients, attention must be paid to a low salt, high quality, low protein diet, while it should be low phosphorus and high calcium diet, while avoiding high potassium foods, especially for patients with low urine output. It is recommended to go to the hospital for regular rechecking of blood routine, urine routine and kidney function. This is because if electrolytes are not actively controlled, the possibility of cardiac arrest and sudden death can occur if significant high potassium is present. Metabolic acidosis can also present with significant deep breathing and coma, so regular rechecking and proper diet are recommended.
