According to research reviewed by Gram Research, people with ileostomies face elevated risks of kidney disease (0-64%), bone weakness (29-48%), and metabolic disorders (12-28%), though wide variation suggests individual risk factors significantly influence disease development. Comprehensive monitoring with healthcare providers is essential for early detection.
Researchers looked at what health problems people with ileostomies might develop over time. An ileostomy is a surgical opening that allows waste to leave the body through the belly instead of the rectum. They found that people with ileostomies may have higher chances of developing kidney problems, bone weakness, blood disorders, and other health issues. However, the studies they reviewed were quite different from each other, making it hard to know exactly how common these problems really are. More research is needed to better understand these risks.
Key Statistics
A scoping review analyzing 20 studies with sample sizes ranging from 14 to nearly 20,000 participants found kidney disease rates in ileostomy patients varied from 0% to 64% depending on the study population and methodology.
Bone thinning (osteopenia) affected 29% to 48% of people with ileostomies, while more severe bone loss (osteoporosis) occurred in 5% to 12% across reviewed studies conducted through April 2025.
Metabolic diseases affecting nutrient processing occurred in 12% to 28% of ileostomy patients, with vitamin B12 deficiency ranging from no increased risk to affecting nearly 32% of individuals in different studies.
Blood disorders like anemia were documented in approximately 7% of ileostomy patients, highlighting the need for regular hematologic monitoring in this population.
The Quick Take
- What they studied: How often people with ileostomies develop long-term health problems related to nutrition and diet
- Who participated: Adults with ileostomies from 20 different studies, ranging from 14 to nearly 20,000 people per study
- Key finding: Health problems varied widely - kidney disease affected 0% to 64% of people, while bone weakness affected 29% to 48%
- What it means for you: If you have an ileostomy, work closely with your healthcare team to monitor for these potential health issues, but remember that risks vary greatly between individuals
The Research Details
This was a scoping review, which means researchers searched through medical databases to find all existing studies about chronic diseases in people with ileostomies. They looked through five major medical databases from the very beginning until April 2025, focusing specifically on kidney disease, bone problems, blood disorders, and metabolic issues that might be related to diet and nutrition changes after ileostomy surgery.
This type of research is important because it gives us the ‘big picture’ of what’s already known about ileostomy-related health problems. Since there are currently no specific guidelines for managing these issues, understanding what research exists is the first step toward better care.
The researchers followed strict scientific guidelines for reviewing studies and had multiple reviewers check each study independently. However, they found that most of the existing research involved small groups of people and used different methods, which makes it harder to draw firm conclusions.
What the Results Show
The review found that people with ileostomies may develop several types of health problems over time. Kidney disease was the most studied issue, with rates ranging dramatically from 0% to nearly 64% depending on the study. Bone problems were also common, with bone thinning (osteopenia) affecting 29% to 48% of people and more severe bone loss (osteoporosis) affecting 5% to 12%. Blood problems like anemia occurred in about 7% of people, while vitamin B12 deficiency varied widely from no increased risk to affecting nearly 32% of people.
Metabolic diseases, which affect how the body processes nutrients and energy, occurred in 12% to 28% of people with ileostomies. The researchers noted that the wide ranges in these numbers suggest that many factors influence who develops these problems and when.
This appears to be the first comprehensive review specifically looking at nutrition-related chronic diseases in people with ileostomies. Previous research existed but hadn’t been pulled together to see the overall picture.
The biggest limitation was that the studies reviewed were very different from each other in terms of how they were conducted, who participated, and how they measured outcomes. Many studies also had small numbers of participants, making it difficult to determine true risk rates.
The Bottom Line
If you have an ileostomy, regular monitoring for kidney function, bone health, blood counts, and vitamin levels appears important based on this research. Work with your healthcare team to develop a personalized monitoring plan, as individual risks may vary significantly.
This research is most relevant for adults who have had ileostomy surgery and their healthcare providers. People considering ileostomy surgery should also be aware of these potential long-term considerations.
The research doesn’t clearly establish when these problems typically develop, highlighting the need for ongoing monitoring rather than expecting issues at specific timepoints.
Frequently Asked Questions
What health problems are most common in people with ileostomies?
Kidney disease (0-64%), bone weakness (29-48%), and metabolic disorders (12-28%) are most frequently studied. However, rates vary widely between individuals, suggesting personal factors significantly influence risk development.
How often should someone with an ileostomy get health screenings?
Regular monitoring for kidney function, bone health, blood counts, and vitamin levels is recommended, though specific intervals should be determined by your healthcare provider based on individual risk factors and baseline health status.
Why do health risks vary so much between ileostomy patients?
The wide variation (kidney disease 0-64%, bone problems 29-48%) reflects differences in study methods, participant populations, and individual factors like nutrition, hydration, and underlying health conditions that influence disease development.
Is vitamin B12 deficiency common after ileostomy surgery?
Vitamin B12 deficiency risk varies dramatically across studies, ranging from no increased risk to affecting nearly 32% of patients. Individual monitoring is essential since absorption varies significantly between people with ileostomies.
