Nutritional Support and Guidance for Kidney Patients by Nefrontida’s Clinical Dietitians
At all stages of kidney disease, certain dietary adjustments may be necessary, particularly regarding the intake of protein, sodium, potassium, phosphorus, and fluids. Personalized guidance from a Clinical Dietitian, based on each patient’s specific needs, can help incorporate favorite meals while maintaining optimal biochemical levels.
Personalized guidance from a Clinical Dietitian, based on each patient’s individual data, can help incorporate favorite meals while maintaining the desired biochemical values.
- Depending on the stage of nephropathy, adjustments should be made to protein intake. Usually, in the stages before dialysis (depending on the severity of the disease), a reduction in protein consumption is recommended. In contrast, during dialysis (whether hemodialysis or peritoneal dialysis), patients are advised to increase their protein intake through their diet. Protein-rich foods, such as meat, poultry, fish, eggs, and legumes, can be properly incorporated into the diet with appropriate guidance to ensure the right frequency and portion size without affecting biochemical indicators.
- It is essential to limit sodium intake both during cooking and at the table, as well as to reduce the consumption of foods high in salt, such as ready-made broths, canned foods, baked goods, chips, salted nuts, processed meats, and cheeses. Alternative low-salt options are preferred, such as salt-free broths, low-salt cheeses, and boiled cold cuts. The use of herbs and spices can add flavor to meals without increasing sodium intake.
- In addition, the intake of foods high in potassium should be carefully managed, as the body cannot easily eliminate excess potassium. It is found in small amounts in many foods, with main sources including fruits, vegetables, and legumes. The Clinical Dietitian can guide patients on how to include these foods in moderation.
- Additionally, the intake of foods high in phosphorus should be carefully consumed, as excess phosphorus cannot be easily removed from the body. It is present in small amounts in many foods, but certain foods can significantly contribute to daily phosphorus intake. Some of these include milk and dairy products, nuts, fish, and seafood. It is important to follow the recommendations provided by your Clinical Dietitian regarding how these foods should be included in your diet.
- In some cases, patients may need to monitor their fluid intake, as the body has difficulty eliminating excess fluids. The allowable fluid limit varies for each patient and is determined by the Nephrologist. It is important to consider all beverages and foods that contain fluids, such as ice cream, jelly, and soups.
Symptoms
Chronic kidney failure and acute kidney failure present with similar symptoms, though they have different causes. The symptoms you experience may depend on how damaged your kidneys are and how effectively they can filter your blood. It is common for symptoms to appear only when kidney function is significantly impaired. However, certain signs of kidney disease—such as swelling around the eyelids, ankles, or generalized body swelling—may also occur even when kidney function appears normal.
Mild kidney failure
In cases of mild kidney dysfunction, you may have no noticeable symptoms. However, some early signs may include:
– Presence of blood in the urine.
– Foamy urine during urination
Severe kidney failure
When kidney function is significantly reduced, you may experience one or more of the following symptoms:
– Severe fatigue.
– Itching of the skin.
– Reduced appetite.
Very Severe Kidney Failure
In advanced stages, symptoms become more pronounced and may include:
– Nausea and vomiting.
– Swelling in the legs.
– Shortness of breath.
– Heart rhythm disturbances (arrhythmias).
