Hemodialysis is a method of treating kidney disease, typically used to replace the kidney's function of filtering blood. In hemodialysis, the patient's blood is filtered and cleaned through a device called a dialysis machine to remove accumulated waste and excess water from the body, and then returned to the patient's body.
For patients with kidney disease, hemodialysis is a very important treatment method that can effectively alleviate disease symptoms and prolong the patient's life. However, hemodialysis can also have some impact on the patient's life. Patients need to go to the hospital regularly for treatment, which usually lasts for several hours and requires cooperation with dialysis machines for treatment. In addition, patients need to adjust their diet and limit the intake of certain nutrients in order to control their body's water and electrolyte levels.
1、 The Importance of Dietary Adjustment for Hemodialysis Patients
Dialysis patients may experience discomfort and even dangerous situations due to impaired kidney function, which can result in the accumulation of metabolic waste and fluids in the body. Therefore, appropriate dietary and drinking habits are crucial for dialysis patients.
Dietary adjustments can help dialysis patients control blood pressure and blood sugar, maintain a healthy weight and dietary balance, avoid excessive or insufficient intake of protein, sodium, potassium, and phosphorus, thereby reducing the risk of complications.
Appropriate dietary and drinking habits can also improve the effectiveness of treatment. Dialysis patients need to control their fluid intake to ensure the effectiveness of dialysis treatment. If dialysis patients consume too much fluid, it may lead to excessive blood volume, thereby reducing the effectiveness of dialysis. Appropriate dietary and drinking habits can ensure that the patient's blood volume is within a reasonable range and improve the effectiveness of dialysis treatment.
Moreover, appropriate dietary and drinking habits can improve the quality of life of dialysis patients, alleviate their physical discomfort and digestive problems, and enhance their mental health and life satisfaction.
2、 The basic principles of diet for hemodialysis patients
(1) In addition to the importance of dietary adjustments that hemodialysis patients need to follow, controlling protein intake, limiting sodium intake, controlling potassium intake, and controlling phosphorus intake are the basic principles of diet for hemodialysis patients. Here is a detailed introduction to these basic principles:
1. Control protein intake: Dialysis patients need to limit protein intake because protein is an important burden for kidney filtration. Dialysis patients should control the daily intake of protein, and the specific control standards should be determined according to each individual's situation. Generally speaking, the protein intake of dialysis patients should be between 0.6 grams and 0.8 grams per kilogram of body weight. In addition, patients should choose high-quality proteins such as chicken, fish, protein, and legumes.
2. Limit sodium intake: Dialysis patients need to pay attention to the sodium content in their diet to avoid problems such as edema and hypertension. Dialysis patients should control their daily sodium intake below 2000 milligrams, which means they should reduce their intake of high salt foods such as processed foods, pickled products, salted meat, and soy sauce. Meanwhile, patients should be encouraged to consume fresh fruits and vegetables to help reduce sodium intake.
3. Control potassium intake: Kidney dialysis patients also need to limit potassium intake because the kidneys cannot effectively eliminate excessive potassium from the body, which may lead to heart and muscle problems. The potassium intake of dialysis patients should be controlled below 2000 milligrams per day. Patients should avoid consuming high potassium foods such as bananas, kiwis, potatoes, spinach, beans, and nuts.
4. Control phosphorus intake: Dialysis patients need to limit the phosphorus content in their diet to avoid hyperphosphatemia. Dialysis patients should consume less than 800 milligrams of phosphorus per day. Patients should avoid consuming high phosphorus foods such as meat, dairy products, and legumes.
（2） Other dietary principles for dialysis patients:
1. Increase carbohydrate intake: Dialysis patients can increase carbohydrate intake to provide energy and avoid waste from protein metabolism.
2. Control fluid intake: Dialysis patients need to control their water intake to avoid problems such as water poisoning and heart failure.
3. Increase intake of vitamins and minerals: Dialysis patients need to consume enough vitamins and minerals because their kidneys cannot retain them well in the body.
4. Personalized diet: Dialysis patients need to develop a suitable diet plan based on their own situation, and can consult with nutritionists or doctors for advice.
5. Avoid consuming foods high in sugar, fat, and salt: These foods can easily cause obesity, high blood pressure, and worsen the condition of dialysis patients.
The above principles can help hemodialysis patients arrange their diet reasonably, reduce the risk of complications, improve treatment effectiveness, and enhance their quality of life.
2、 Dietary Guidelines for Hemodialysis Patients
The following are dietary guidelines for hemodialysis patients:
(1) Low Sodium Diet: Hemodialysis patients should avoid consuming foods with high sodium content, such as salt, pickled foods, and processed meats. Patients should choose fresh foods such as vegetables, fruits, chicken, fish, etc. In addition, using low sodium salt instead of regular salt is also a good choice.
（2） Low phosphorus diet: Hemodialysis patients should limit their consumption of phosphorus rich foods, such as dairy products, beans, meat, etc. Patients should choose foods with low phosphorus content, such as chicken, fish, fruits, vegetables, etc. In addition, using low phosphorus foods instead of high phosphorus foods is also a good choice.
（3） Low potassium diet: Hemodialysis patients should limit their consumption of potassium rich foods such as bananas, potatoes, oranges, etc. Patients should choose foods with low potassium content, such as apples, strawberries, onions, celery, etc. In addition, using cooking techniques such as soaking high potassium vegetables in water or cutting high potassium foods into small pieces during the cooking process is also a good choice.
（4） Protein rich foods: Hemodialysis patients need to consume sufficient protein to maintain a healthy level. Patients should choose protein rich foods such as chicken, fish, eggs, beans, etc.
（5） Food that controls water intake: Hemodialysis patients need to control their water intake to avoid excessive water in the body. Patients should avoid consuming foods that contain a lot of water, such as watermelon, oranges, tomatoes, etc. Patients should choose foods with low moisture content, such as bread, rice, meat, etc.
For hemodialysis patients, dietary adjustments are very important as they can help reduce the risk of complications and improve their quality of life. Therefore, it is recommended that patients choose food reasonably and control their intake under the guidance of doctors and nutritionists in order to better manage their health status. In addition to dietary adjustments, patients should also undergo regular dialysis treatment, follow medical advice, and maintain close communication with the medical team to ensure optimal treatment outcomes.
