Short Bowel Syndrome

For patients & families
Short bowel syndrome happens when a child's small intestine cannot absorb enough nutrition, fluids, and calories to support survival and growth, requiring intravenous feeding (parenteral nutrition or TPN) for at least 60 days [e296-c1, e4741-c2]. The most common causes in babies include birth defects like intestinal atresia or gastroschisis, and acquired conditions like necrotizing enterocolitis [e4741-c5, e4741-c6]. After significant bowel loss, the remaining intestine can adapt over one to two years, sometimes allowing children to transition fully to oral or tube feeding . Doctors have learned that breast milk supports this adaptation best, and keeping some nutrition flowing through the gut—even small amounts—helps the intestine heal and grow [e4742-c15, e4742-c20]. Survival has improved dramatically: specialized intestinal rehabilitation programs now report over 90% long-term survival, compared to much lower rates decades ago [e4741-c20, e10273-c4]. Treatment involves a team of specialists managing nutrition, preventing infections in IV lines, protecting the liver from TPN complications, and sometimes performing surgery to reshape dilated bowel [e4741-c19, e296-c26]. Some children need TPN for months or years, while others eventually eat normally; the outcome depends on how much bowel remains, whether the colon is intact, and how well the intestine functions [e296-c6, e10226-c21].
