Hydration knowledge, attitudes and practices among people living with an ileostomy: A cross-sectional multinational survey
This multinational cross-sectional survey reveals that dehydration and high-output stomas are prevalent among ileostomates in the UK, Ireland, and Australia, driven by low hydration knowledge, significant barriers to fluid intake, and specific clinical factors, thereby highlighting the urgent need for targeted education and ongoing monitoring.

The human body is a master of balance, constantly adjusting how much water it keeps and how much it releases. Under normal circumstances, the large intestine acts as a final checkpoint, reabsorbing fluid from food waste before it leaves the body. This process ensures that the body stays hydrated without needing to drink excessive amounts of water. However, for some people, this checkpoint is removed entirely. When the small intestine is surgically connected directly to the skin of the abdomen to create an opening called a stoma, the digestive system bypasses the large intestine. Without this crucial reabsorption stage, the body loses fluid and essential salts much faster than usual. This condition, known as an ileostomy, turns a routine biological process into a daily challenge of managing hydration. If the body loses more fluid than it takes in, the result is dehydration, a state that can lead to fatigue, confusion, and serious health complications.
A new study set out to understand how people living with this condition manage their fluid intake and what they know about keeping themselves hydrated. Researchers from universities in the United Kingdom, Ireland, and Australia surveyed 366 individuals who have an ileostomy. They wanted to see if these individuals were drinking enough, whether they understood the specific risks of their condition, and what barriers stopped them from staying hydrated. The survey asked participants about their daily habits, the medications they took, and how they felt physically. The researchers also looked at whether the amount of fluid leaving the body through the stoma—often called output—was higher than the amount of fluid being drunk. When the output exceeds the intake, the condition is classified as a high-output stoma, which carries a significantly higher risk of dehydration.
The results revealed a concerning picture. Nearly half of the participants showed signs of dehydration based on the color of their urine, a simple but reliable indicator of fluid levels. One-third of the group was classified as having a high-output stoma, meaning they were losing more fluid than they were replacing. The study found that this high-output group was more likely to be female, to have had the surgery more recently, and to be living in Australia. They also reported taking more medications and experiencing more symptoms of dehydration, such as thirst, fatigue, and trouble concentrating. Interestingly, the amount of time since the surgery did not seem to make the problem go away; even people who had lived with an ileostomy for many years still struggled with these issues, suggesting that the risk is a long-term reality rather than just a temporary post-surgery hurdle.
Knowledge about how to stay hydrated was surprisingly low across the entire group. Many participants did not know which fluids were best to drink or how to recognize the early signs of dehydration. The study showed that people who felt they faced more barriers to drinking water—such as not knowing what to drink, finding it inconvenient to carry fluids, or worrying about bathroom access—were also the ones who drank less water, ate fewer fruits and vegetables, and felt more dehydrated. A common practice among these individuals was to restrict their intake of fruits and vegetables to try to slow down the flow from the stoma. While this might reduce output, it also removes a natural source of water and nutrients, potentially making dehydration worse. Similarly, while many people added salt to their food to replace lost minerals, this alone did not seem to solve the problem of low fluid levels.
The way people managed their condition often relied on trial and error rather than clear guidance. When output increased, many tried to adjust their diet or fluid intake on their own, but approaches varied wildly; some drank more, while others drank less. Only a small number actively sought out new information or peer support to learn better strategies. When they did seek help from medical professionals, it was often after they had already tried and failed to manage the situation themselves. The researchers noted that the types of fluids people drank were mostly water, tea, or coffee, which are less effective at replacing lost salts compared to specialized oral rehydration solutions. This gap between what medical guidelines suggest and what people actually do in their daily lives points to a need for better education. The study concludes that staying hydrated is a persistent challenge for people with an ileostomy, and that improving their knowledge and providing ongoing support could help prevent the cycle of dehydration and its associated health risks.
