Mangoes are not recommended for uremic patients who are not on dialysis, and a small amount of mangoes can be eaten by uremic patients on regular dialysis. Patients with uremia, especially those who are not on dialysis, are not recommended to eat mangoes. Fresh mango contains high amount of potassium, eating mango may lead to hyperkalemia, and severe hyperkalemia may lead to cardiac arrhythmia or even cardiac arrest. Therefore, eating mangoes is usually not recommended for non-dialysis uremic patients. In case of patients on regular dialysis, a small amount of mango can be eaten. The potassium ions in mangoes will be filtered out through dialysis and have little effect on the patient. Therefore, patients on regular dialysis can eat a small amount of mango. Patients with uremia are advised to go to regular hospitals in time and standardize their treatment under the guidance of doctors.
