Shiitake mushrooms are usually not recommended for uremic patients who are not on dialysis, and a small amount of shiitake mushrooms can be eaten by uremic patients who are on regular dialysis. Patients with uremia, especially those who are not on dialysis, are not recommended to eat shiitake mushrooms. Shiitake mushrooms contain high potassium and purine, which may lead to hyperkalemia and hyperuricemia, and severe hyperkalemia may lead to cardiac arrhythmia and even cardiac arrest. Therefore, mushrooms are usually not recommended for non-dialysis uremic patients. If the patient is on regular dialysis, a small amount of shiitake mushrooms can be eaten. Potassium ions and purines in shiitake mushrooms will be filtered out through dialysis, which will have less impact on patients, therefore, patients on regular dialysis can eat a small amount of shiitake mushrooms. Patients with uremia are advised to go to regular hospitals in time, standardize treatment under the guidance of doctors, and consult professional doctors for dietary advice if necessary.
