Patients with uremia should pay attention to reduce the intake of high potassium foods, it is not recommended that patients with uremia eat melon. The potassium content of melon is high, and patients with uremia have reduced urine output, severely impaired renal function, and significantly reduced ability to excrete potassium. Patients are prone to hyperkalemia when ingesting melons. Hyperkalemia can lead to cardiac arrhythmia, posing a potential threat to patients’ life safety. In addition, patients with uremia should avoid eating fruits high in potassium such as bananas. Patients should eat more high-birth-price animal proteins with high amino acid content such as egg white, poultry, pork and mutton, etc., and less vegetable proteins such as soybean products, less or no pickled and preserved products, and less high-purine foods such as animal offal, shrimps, crabs and other seafood. Uremia patients should go to the hospital in time, under the guidance of professional physicians to develop diet and medication programs.
