The Importance of Diet in Dialysis
The importance of diet for chronic kidney disease (CKD) patients on dialysis cannot be overstated. Dialysis is a life-saving treatment that helps remove waste products and excess fluid from the body when the kidneys are no longer able to perform these functions effectively.
However, dialysis alone is not sufficient to manage the condition completely. A well-planned and tailored diet is essential to complement dialysis treatment and optimize overall health for patients with kidney disease on dialysis.
Diet plays a crucial role in managing several aspects of CKD, including controlling blood pressure, maintaining fluid balance, managing electrolyte levels, and preventing malnutrition. By following a specialized renal diet, people with kidney failure can minimize the workload on their kidneys, prevent further kidney damage, and improve their overall quality of life.
A renal diet for people with kidney disease on dialysis typically involves restrictions on sodium, potassium, phosphorus, and fluid intake. These restrictions are necessary to maintain proper fluid balance, control blood pressure, and prevent the buildup of harmful substances in the body. Additionally, protein intake needs to be monitored and adjusted to prevent malnutrition and minimize the strain on the kidneys.
Working closely with a registered dietitian who specializes in renal nutrition is crucial for people with kidney problems on dialysis. The dietitian can create a personalized meal plan that meets the specific needs and restrictions of each patient. Regular monitoring of lab values, such as electrolytes and blood chemistry, helps assess the effectiveness of the diet and allows for adjustments as needed.
Adhering to a renal diet in conjunction with dialysis treatment can help slow the progression of CKD, reduce complications, and improve overall health outcomes. It is important for people with kidney failure to prioritize their dietary guidelines and actively participate in their own care by making informed food choices and seeking support from healthcare professionals.
Understanding Potassium in the Dialysis Diet
The potassium that builds up in the kidneys is removed during dialysis, so high potassium foods may not be a potential problem, and possibly may be included in your diet in small amounts.
However, you’ll have to have a blood test to determine where your potassium levels are while you’re getting dialysis. The test can help you determine if you’re on track with your potassium, or if your levels are too low, too high or just right. Both high potassium and low potassium cause symptoms and are a threat to your health.
Remembering what foods have extra potassium will help you know how to adjust your diet. The two food groups high in potassium are fruits and vegetables.
One would think that no matter how sick a person is, fruits and vegetables would always be good to eat, but in this case, they aren’t and it’s possible you may have to eat less of them. You can still eat the fruits and vegetables that are not as high in potassium, but they should be limited in serving size.
Here’s a list of high potassium foods to avoid:
- Oranges and orange juice
- Garbanzo beans
- Prunes and prune juice
- Black and baked beans
- Tomatoes, tomato sauce and tomato juice
- Red and white beans
- Lima beans and lentils
- Potassium-based salt substitutes
Hyperkalemia is a condition characterized by elevated levels of potassium in the bloodstream, and it can lead to various symptoms and complications for dialysis patients. Symptoms of hyperkalemia may include muscle weakness, fatigue, palpitations, irregular heart rhythms, and numbness or tingling sensations. In severe cases, it can even lead to cardiac arrest.
Monitoring potassium intake in the diet is crucial for dialysis patients to prevent the risks associated with hyperkalemia. Following a potassium-restricted diet helps maintain potassium levels within a safe range, reducing the likelihood of experiencing these symptoms and complications and promoting better overall health and well-being.
The Role of Phosphorus in the Dialysis Diet
Phosphorus is an important nutrient to consider when managing a dialysis-friendly lifestyle, as imbalances can have serious health implications. It is essential for bone health and many other body functions.
Major sources of phosphorus include dairy products, meats, poultry, fish, nuts, legumes and grains. A person on dialysis should limit their intake of high phosphorus foods while also keeping in mind the fluid restrictions associated with the diet.
|Foods High in Phosphorus
|Foods Low in Phosphorus
|Fruit & Vegetables
Interestingly, the other foods believed to be good for you on a diet besides fruits and vegetables are high in phosphorus. Here’s a list below. Some of the items on the list will give amounts you can eat.
- eggs – only one allowed daily
- dried beans and peas – do not eat at all
- meat, poultry, wild game meats, seafood and fish – 7 – 8 oz. allowed daily
- milk – limited to ½ cup day
- chocolate – none allowed
- nuts and seeds – not allowed
Anyone might think that eating a nice dinner of salmon, potatoes, beans, salad, tomato juice, whole grain dinner roll with butter, and a slice of home-baked cherry pie with ice cream would be ideal before dialysis but in reality, it can contribute to causing symptoms and making you sicker.
Hyperphosphatemia, the condition characterized by high levels of phosphorus in the bloodstream, can lead to significant complications for dialysis patients. Extra phosphorus can cause imbalances in calcium levels, leading to weakened bones, bone pain, and an increased risk of fractures. It can also contribute to the calcification of blood vessels, increasing the risk of cardiovascular complications such as heart disease and stroke.
It is important for dialysis patients to limit phosphorus intake to prevent these complications. Restricting high-phosphorus foods and taking phosphate binders as prescribed helps maintain phosphorus levels within a safe range, supporting bone health and reducing the risk of cardiovascular problems.
Protein: Balancing Needs in Dialysis
Getting enough protein in the diet is crucial for dialysis patients undergoing both peritoneal dialysis and hemodialysis. Protein is an essential nutrient that plays a vital role in the body's overall health and well-being. It is responsible for tissue repair, immune function, and maintaining muscle mass.
Dialysis patients often experience protein loss during the treatment process, which can lead to muscle wasting and malnutrition if not adequately addressed. Therefore, it is important for dialysis patients to consume sufficient protein to meet their increased needs and prevent these complications.
For patients on peritoneal dialysis and hemodialysis, the recommended dietary protein intake is typically in the range of 1.0–1.2 grams of protein per kilogram of body weight per day. This range helps to meet the increased demands for protein due to the dialysis treatment and to prevent muscle breakdown.
Protein sources should be of high quality, including lean meats, poultry, fish, eggs, and dairy products. These sources provide essential amino acids necessary for muscle repair and maintenance. Plant-based proteins, such as legumes, tofu, and grains, can also be included in the diet for variety and to meet individual preferences.
Protein intake needs to be monitored and adjusted based on the individual's specific needs, kidney function, and other factors. Excessive protein intake can put additional strain on the kidneys and may lead to the accumulation of waste products. On the other hand, inadequate protein intake can result in malnutrition and muscle wasting.
Working closely with a registered dietitian who specializes in renal nutrition is essential for dialysis patients to develop an individualized meal plan that meets their protein needs while considering their specific dietary restrictions and preferences. Regular monitoring of nutritional status and lab values helps ensure that protein intake is optimized and adjusted as necessary.
Getting enough lean protein in the diet is essential for people with kidney problems to maintain muscle mass, support immune function, and prevent malnutrition. Following the recommended protein intake guidelines, incorporating high-quality protein sources, and working with a dietitian helps dialysis patients optimize their protein intake and overall nutritional status.
Hidden Phosphorus in Processed Foods
Navigating processed foods can be tricky, as many contain hidden phosphorus that can make it difficult to keep your phosphorus levels in balance. It's important to understand how much phosphorus is in the food you eat and to track your nutrient levels closely.
As part of a dialysis renal diet, you should avoid processed snacks, such as chips and cookies, which often contain high amounts of sodium and hidden sources of phosphorus. Pay close attention to food labels and look for any added sources of phosphorus or sodium when selecting which foods to eat. A good rule of thumb is if it doesn't say 'phosphorus-free' on the label, there's likely some form of phosphorus present.
Protein sources such as lean meats, fish, poultry, eggs, or dairy are generally low in phosphorus but still provide necessary protein for your body's needs. Eating fresh fruits and vegetables is also an excellent way to get plenty of nutrients without unnecessary additives.
Phosphorus is disguised in a lot of processed foods so be wary. Read the label for preservatives such as the following:
- sodium phosphate
- monocalcium phosphate
- phosphoric acid
- dicalcium phosphate
These preservatives are commonly found in meats and beverages.
If you're unsure about a particular food item's ingredients or nutritional content, speak with your healthcare provider who can help you make wise choices about what foods are best for managing your kidney diet while on dialysis.
With careful attention and tracking of dietary intake, you can make sure you stay in control of the balance between protein and phosphorus needs while on dialysis.
