Brother Wang has been suffering from renal failure for several years. He is very careful when he eats, and he is worried that it will make his condition worse. Just a few days ago, Brother Wang made an appointment for a medical examination on time. Because he was worried about being late, he ate a cantaloupe and went out. He fainted in the hospital just after the examination. Fortunately, he was rescued in time. It is understood that Brother Wang was in a very urgent situation at the time. His heartbeat dropped to 27 beats per minute, the heart may stop beating at any time, and the blood potassium level reached 7.9 mmol. The doctor said that Brother Wang suffered from severe hyperkalemia.

What is hyperkalemia?

Under normal circumstances, the blood potassium level is 3.5~5.5 mmol. Potassium is an essential nutrient for the body, involved in nerve conduction, heart beating and muscle contraction. Both high blood potassium and low blood potassium will threaten the health of the heart and affect nerve conduction. The former can inhibit the beating of the heart, and the latter can cause arrhythmia.

Can patients with kidney disease not eat cantaloupe?

For people with healthy kidneys, eating high-potassium fruit does not induce hyperkalemia. However, patients with chronic renal failure should pay attention, and hyperkalemia may be caused by eating high-potassium foods.

Cantaloupe is not the culprit of hyperkalemia, it may be Mr. Huang’s own blood. Potassium is not well controlled, triggered by eating cantaloupe. Among all potassium-containing foods, coconut has the highest content, followed by fresh dates and jackfruit.

The root cause of hyperkalemia is chronic renal failure. The kidneys are the organ that produces urine and can excrete excess water and metabolic waste from the body. If potassium intake is too much, the kidneys can excrete the excess potassium ions to maintain electrolyte balance.

However, patients with chronic renal failure have weakened renal function, unable to excrete acidic substances and excess water from the body in time, and their ability to regulate and excrete is weakened. Eating high-potassium foods will make potassium in the body accumulation, which induces hyperkalemia.

In addition, the accumulation of too many acidic substances in the body of patients with chronic renal failure is easy to induce metabolic acidosis. Metabolic acidosis can promote the entry of potassium in cells into the blood, resulting in high potassium blood.

Statistics from 2015 to 2017 show that the population with chronic kidney disease is Hyperkalemia is most likely to occur, followed by heart failure. If kidney disease progresses to uremia, there is an increased risk of hyperkalemia.

What can kidney disease patients eat?

It is rare for patients with kidney disease to eat a cantaloupe to cause hyperkalemia. Therefore, there is no need to spend time alone and dare not eat fruit. Dietary intervention plays an important role in the treatment of the disease, and proper eating can effectively prevent the disease from getting worse.

1. Tomatoes

Tomatoes are the most common vegetables in the vegetable market, and the price is affordable And high nutritional value, can play a cooling blood and liver and stomach digestion effect. Tomatoes contain lycopene and vitamin C, which are antioxidant substances that can protect kidney tissue from oxidative damage.

2, winter melon

The water content of winter melon is relatively high, and at the same time, it can clear heat and detoxify, reduce swelling, diuresis, and reduce phlegm. Kidney disease patients eat winter melon in moderation not only to supplement the water they need, to speed up their metabolism, but also to relieve the problem of edema. Winter squash is a typical low-potassium and low-sodium food, and does not increase the burden on the kidneys.

3. Melon

Summer is a good season to eat melon, except for the carbohydrates In addition to compounds, it also contains a variety of vitamins and citric acid, which can provide nutrients to the body and effectively protect kidney health.

Message from the doctor

Chronic renal failure patients on diet Be careful, stay away from high-potassium and high-phosphorus foods, such as bananas, yams, potatoes, animal offal and nuts; provide high-quality protein, 0.6 grams of protein per kilogram of body weight per day, such as milk, eggs and fish and lean meat, etc. . At the same time, you should actively improve your unhealthy lifestyle, stay away from cigarettes and alcohol, maintain moderate exercise, and actively control your weight. Patients with chronic renal failure should strictly follow the doctor’s orders for regular reexamination, and pay more attention to their own symptoms. If there is any abnormality, they should seek medical treatment as soon as possible.
