　　Is it okay for patients with kidney disease to eat cantaloupe?

　　Due to oliguria, potassium in the body cannot be excreted in time, causing excessive potassium to be retained in the body and cause hyperkalemia. If the patient is complicated by hyperkalemia, a low-potassium diet should be given. If the daily urine output is greater than 1000 ml or the blood potassium is normal, there is no need to limit potassium intake. During potassium-restricted meals, fruit juices should be avoided and vegetables and fruits should be chosen carefully. If the patient's daily urine output increases, the blood potassium level should be observed if it is greater than 1500 ml. If it is too low, potassium supplementation is required.

　　The potassium ion content in cantaloupe is quite high. Due to the reduced glomerular filtration rate and reduced renal tubular function in patients with renal failure, the ability to process potassium is reduced. Eating high-potassium foods can cause bradycardia and even accidents. Therefore, people with kidney failure should not eat cantaloupe when they have oliguria. Bananas are also rich in potassium. According to testing, every 100 grams of banana contains 283 to 472 mg of potassium. Therefore, people with kidney failure should not eat bananas when they have oliguria.

　　Acute renal failure can be divided into three stages: oliguric stage, polyuric stage and recovery stage according to the evolution of the disease. Dietary treatment should focus on clinical The different performances of each phase are used to adjust different nutrients.

　　Those with a 24-hour urine output of less than 400 ml are oliguria, and those with less than 50 ml are anuria. Foods high in potassium should be restricted during both the oliguric and anuric periods. Potassium retention in the body may occur in the later stages of renal failure. Depending on whether there is hyperkalemia when oliguria occurs, the intake of potassium salt should be adjusted to avoid hyperkalemia caused by excessive exogenous intake of potassium.

　　When blood potassium increases and urine output decreases (less than 1000 ml/day), it is necessary to appropriately limit foods with high potassium content, such as various dry foods (seaweed, mushrooms, dried dates, lilies, etc.), most vegetables (cauliflower, rape, etc.), fruits such as oranges, bananas, cantaloupe, and various meats, potatoes, and whole grains. When urine output increases and blood potassium decreases, potassium must be supplemented accordingly.

　　Generally, when the urine output is 1500-3000 ml/day, you can choose foods with high potassium content, such as lean meat, milk, eggs, potatoes, green leafy vegetables, tea, sunflower seeds, cereals, bananas, cantaloupe, oranges, lemons, apricots, plums, etc. Generally speaking, potassium salt supplementation should be adjusted in time according to blood potassium levels.
