Dialysis patients must follow a strict diet to manage their condition effectively. The hemodialysis diet is tailored to each patient and aims to reduce the amount of fluid and waste that accumulates between treatments. This involves limiting certain food groups, such as sodium, potassium, phosphorus, and fluids, while increasing protein intake. The diet is designed to keep dialysis patients well-nourished and feeling their best, while also reducing the risk of health complications.

What You'll Learn
Limit sodium and salt intake
Dialysis patients are typically advised to follow a renal diet, which involves limiting sodium and salt intake, among other restrictions. This is because sodium causes the body to retain more fluid, which can lead to high blood pressure and discomfort during dialysis sessions.
To prevent this, it is recommended that sodium intake be limited to less than 2,000-2,300 mg per day, which is equivalent to about one teaspoon of salt. This involves more than simply avoiding the salt shaker; it also means limiting processed foods with high sodium content, such as deli meats, canned foods, and chips. It is important to read nutrition labels, as some foods that do not taste salty may still contain high levels of sodium.
In addition to helping control fluid levels, limiting sodium can also reduce thirst and lower blood pressure. This is particularly important for dialysis patients, as their kidneys may struggle to eliminate excess sodium from the body. By reducing sodium intake, patients can help manage their blood pressure and prevent hypertension and other health issues.
Dialysis patients should also be mindful of their fluid intake, as excess fluid can build up in the body and lead to swelling, shortness of breath, or high blood pressure. This includes not only beverages but also foods with high water content, such as gelatin, ice, sherbet, watermelon, sauces, and gravies. By working with a renal dietitian, dialysis patients can develop a personalized plan to monitor and limit their sodium and fluid intake, ensuring optimal health and comfort during treatment.

Monitor fluid intake
Monitoring and limiting fluid intake is an important part of a dialysis patient's diet. This is because, during dialysis, the body can only remove a certain amount of fluid at a time, and too much fluid in the body can lead to discomfort, including swelling, shortness of breath, or high blood pressure.
Fluid intake is not limited to what you drink; it is also found in some foods, including gelatin, ice, sherbet, watermelon, sauces, and gravies. Therefore, it is important to keep track of the amount of liquid you consume in both food and drink. A renal dietitian will help you plan your meals and give you guidelines to monitor your fluid intake. They will also make a diet plan that fits your needs and preferences, and they will work with your doctor to determine the right amount of fluid for you.
Dialysis patients need to be careful about their sodium intake, as sodium causes the body to retain more fluid and can lead to higher blood pressure. Sodium is found in many canned, packaged, frozen, and fast foods, as well as condiments, seasonings, and meats. It is recommended that sodium intake be less than 2,000-2,300 mg per day, which is about one teaspoon of salt. This means limiting the use of a saltshaker, but also being mindful of other high-sodium foods like deli meats and chips.
Drinking less fluid and consuming less sodium can help you feel more comfortable before and after your dialysis sessions. It is important to note that limiting fluid intake may lead to lower protein and calorie consumption, so it is crucial to ensure adequate protein and calorie intake, especially since dialysis patients often need higher protein intake to prevent and correct protein-energy wasting.

Eat high-quality protein
For dialysis patients, it is important to eat high-quality protein. This is because high-quality protein produces less waste for removal during dialysis. This means that dialysis treatments will be more effective and patients can feel their best.
High-quality protein comes from meat, poultry, fish, and eggs. Lean meats such as chicken, fish, or roast beef are recommended, as they are low in phosphorus. If you are a vegetarian, ask your renal dietitian about other ways to get protein. Low-fat milk is a good source of protein, but it is also high in phosphorus and potassium, and it adds to your liquid intake.
Processed meats such as hot dogs and canned chilli should be avoided, as they contain high amounts of sodium and phosphorus. Sodium is part of salt and is found in many canned, packaged, frozen, and fast foods, as well as condiments, seasonings, and meats. It is recommended that sodium intake be kept to less than 2,000-2,300 milligrams per day. This will help to prevent fluid from building up between dialysis treatments and will reduce thirst.
Your dietitian will determine the amount of high-quality protein you should eat and will provide you with food lists that indicate which foods are allowed and which ones you should avoid or limit.

Limit potassium
For dialysis patients, diet is a key part of treatment. It can help to reduce the amount of fluid and waste that builds up between treatments, so that patients can feel their best.
Dialysis patients are encouraged to eat high-quality protein, as it produces less waste for removal during dialysis. High-quality protein comes from meat, poultry, fish, and eggs. However, patients should avoid processed meats such as hot dogs and canned chilli, which have high amounts of sodium and phosphorus.
One of the most important aspects of the dialysis diet is limiting potassium. Limits on potassium in the diet are based on the patient's specific blood levels. People who do frequent hemodialysis at home usually do not need to limit potassium. If you do need to limit potassium, you should discuss your options with your dietitian.
If you have high potassium (hyperkalemia), your healthcare provider may advise you to limit certain foods that are higher in potassium. A food that is considered “high-potassium” generally has 200 mg or more potassium per serving. Since the serving size is very important, a large amount of a low-potassium food can easily turn it into a high-potassium food. For example, if you want to include high-potassium vegetables in your diet, you can leach them first. Leaching helps lower the amount of potassium in a vegetable by pulling some (but not all) of the potassium out. Another way to lower the amount of extra potassium in your diet is to avoid drinking or using the liquid from canned fruits, canned vegetables, or the juices from cooked meat.

Take vitamin and mineral supplements
Dialysis patients typically need to follow a special diet to help manage their condition. This often includes limiting fluid intake and reducing the consumption of certain foods and condiments, such as sodium, salt, potassium, phosphorus, and processed meats.
Dialysis patients may also need to take vitamin and mineral supplements, in addition to their modified diet. This is because kidney disease and dialysis can change the amounts of vitamins and minerals required by the body. Moreover, the dietary restrictions of dialysis may limit food groups that normally provide essential vitamins and minerals.
It is important to note that patients should only take supplements ordered by their kidney healthcare professional. This is because certain vitamins and minerals can be harmful if taken in excess or when the patient is on dialysis. Before taking any herbal remedies, dietary supplements, or over-the-counter medicines, patients should consult their healthcare provider to ensure they are safe to take in conjunction with their prescribed treatment.
A renal dietitian can help patients plan their meals and create a diet that is tailored to their individual needs. They can advise on which foods to eat and which to avoid, as well as provide guidelines to monitor fluid intake. Monthly laboratory tests can also help evaluate a patient's mineral balance and vitamin levels.
Dialysis patients often need a higher protein intake to prevent and correct protein-energy wasting. High-quality protein sources include meat, poultry, fish, and eggs. These produce less waste for removal during dialysis. However, it is important to choose lean, low-fat meats that are low in phosphorus, such as chicken, fish, or roast beef.
