Two major international medical organizations have released the first unified guidelines for managing nutrition in peritoneal dialysis patients. According to Gram Research analysis, these comprehensive recommendations cover nutrition screening, dietary choices, handling complications, supplements, and patient education to help prevent malnutrition and improve outcomes for the millions of people worldwide receiving this home-based kidney treatment.
Two major international medical organizations have created the first unified set of guidelines for feeding people who receive peritoneal dialysis, a type of kidney treatment. According to Gram Research analysis, these new recommendations cover everything from checking if patients are eating enough to helping them choose healthy foods and manage complications. The guidelines were developed by kidney doctors, nutritionists, and nurses from around the world and use the highest standards for evaluating medical evidence. The goal is to help patients stay healthier, prevent serious nutrition problems, and feel better while living with dialysis.
Key Statistics
A 2026 joint practice recommendation from the International Society of Renal Nutrition and Metabolism and International Society for Peritoneal Dialysis established the first unified global guidelines for nutrition management in peritoneal dialysis patients, covering five key areas: screening, dietary recommendations, complication management, supplementation, and education.
The new 2026 international guidelines emphasize a multidisciplinary team approach involving nephrologists, dietitians, and nurses working together to prevent protein-energy wasting and optimize nutrition status in peritoneal dialysis patients.
Research reviewed by Gram shows that the 2026 consensus recommendations use the GRADE framework, the highest standard for evaluating medical evidence, to ensure that nutrition guidance for dialysis patients is based on the strongest available scientific research.
The Quick Take
- What they studied: How doctors and nutritionists should manage food and nutrition for people receiving peritoneal dialysis, a home-based kidney treatment
- Who participated: A global team of kidney specialists, registered dietitians, and dialysis nurses who reviewed existing research and expert knowledge to create practical recommendations
- Key finding: The first-ever unified international guidelines now exist to help healthcare teams properly feed dialysis patients, covering screening, dietary choices, supplements, and nutrition education
- What it means for you: If you or a loved one receives peritoneal dialysis, your healthcare team now has clear, evidence-based guidance to help prevent malnutrition and complications. This should lead to more consistent, better nutrition care across different hospitals and countries
The Research Details
This is a practice recommendation, not a traditional research study. Instead of testing a new treatment, a group of international experts reviewed all available scientific evidence about nutrition in peritoneal dialysis patients. They used a formal system called GRADE, which is the gold standard for evaluating how strong medical evidence is. The team included kidney doctors, nutrition specialists, and nurses from multiple countries, ensuring the recommendations reflect global best practices. They organized their guidance into five main topics: checking if patients are eating enough, what foods to recommend, handling nutrition problems when they occur, using supplements, and teaching patients about nutrition.
Before this, there was no single agreed-upon approach to nutrition care for dialysis patients worldwide. Different hospitals and countries used different methods, which meant patients received inconsistent care. Having unified guidelines means all healthcare providers can follow the same evidence-based approach, leading to better and more equal care for all dialysis patients, regardless of where they live
This recommendation is strong because it comes from two major international organizations and was developed by experts from many countries. The team used GRADE, the most rigorous system for evaluating medical evidence. However, this is a consensus document based on existing research rather than a new study, so its strength depends on the quality of the research it reviews. The recommendations include both evidence-based guidance and expert consensus points where research is limited
What the Results Show
The guidelines establish five core areas for nutrition management in peritoneal dialysis patients. First, they provide clear methods for screening and assessing whether patients are getting enough nutrition and monitoring their status over time. Second, they offer specific dietary recommendations tailored to the needs of dialysis patients, who have unique nutritional requirements different from the general population. Third, they address how to manage nutrition problems when patients develop complications during dialysis treatment. Fourth, they guide when and how to use nutrition supplements to fill gaps in patients’ diets. Fifth, they emphasize the importance of educating patients about nutrition so they can make healthy food choices and manage their own diets better. The guidelines stress that a team approach works best, with doctors, dietitians, nurses, and patients all working together.
The recommendations highlight the importance of patient education and health literacy, meaning patients need to understand nutrition basics to make good choices. The guidelines also emphasize that nutrition care should be personalized to each patient’s individual needs, medical conditions, and cultural food preferences. The team noted that preventing protein-energy wasting, a serious condition where patients lose muscle and weight, is a key goal of proper nutrition management. The recommendations also stress the need for regular monitoring and adjustment of nutrition plans as patients’ needs change over time
This is the first unified international guideline on this topic, so there is no previous consensus document to compare it to. However, individual countries and organizations had their own separate recommendations before this. These new guidelines bring together the best evidence from all those previous approaches and create one comprehensive standard that healthcare providers worldwide can follow. This represents a major step forward in standardizing dialysis nutrition care globally
This is a consensus recommendation based on reviewing existing research rather than new research data. The strength of individual recommendations depends on the quality of studies already published. Some areas of nutrition care may have limited research available, so some recommendations are based on expert opinion rather than strong scientific evidence. The guidelines may need updating as new research becomes available. Implementation may vary depending on local resources, healthcare systems, and patient populations in different countries
The Bottom Line
If you receive peritoneal dialysis, work with your healthcare team to follow these new guidelines. Have your nutrition status checked regularly, follow the dietary recommendations your dietitian provides, take any recommended supplements, and actively participate in nutrition education. These evidence-based recommendations are designed to help you stay healthier and prevent serious nutrition problems. Confidence level: High for the overall approach, though individual recommendations vary in strength depending on available research
These guidelines are essential for anyone receiving peritoneal dialysis and their healthcare providers. Nephrologists, primary care doctors, registered dietitians, and dialysis nurses should all use these recommendations to guide patient care. Patients and their families should discuss these guidelines with their healthcare team to ensure they are receiving nutrition care based on the latest evidence. Healthcare administrators and policymakers should consider these guidelines when developing dialysis programs and nutrition services
Benefits from following these guidelines should appear gradually over weeks to months as nutrition status improves and complications are prevented. Regular monitoring every 1 to 3 months will help track progress. Some patients may see improvements in energy levels and muscle strength within 4 to 8 weeks of following proper nutrition recommendations. Long-term benefits include reduced hospitalizations and better quality of life over years of dialysis treatment
Frequently Asked Questions
What should dialysis patients eat to stay healthy?
The new 2026 international guidelines recommend personalized diets based on individual needs, typically including adequate protein (1.2 to 1.3 grams per kilogram of body weight daily), controlled sodium and potassium, and limited phosphorus. Your dietitian will create a specific plan for you
How often should nutrition be checked in dialysis patients?
The 2026 guidelines recommend regular nutrition screening and monitoring, typically every 1 to 3 months, with more frequent checks if problems develop. This includes weight tracking, lab tests like albumin levels, and dietary assessments
Can dialysis patients take nutrition supplements?
Yes, the new guidelines address when supplements are appropriate. Some dialysis patients need protein supplements, vitamin D, or other nutrients. Your healthcare team will determine what you need based on your individual nutrition status and lab results
Why is nutrition education important for dialysis patients?
The 2026 guidelines emphasize that educating patients about nutrition helps them make healthy food choices and manage their own diets better. Patients who understand nutrition basics have better health outcomes and fewer complications
What is protein-energy wasting and why does it matter?
Protein-energy wasting is a serious condition where dialysis patients lose muscle and weight. The new guidelines identify preventing this condition as a key goal because it leads to weakness, more infections, and worse outcomes. Proper nutrition management helps prevent it
