In the treatment of short bowel syndrome, GLP-2 has been shown to be highly effective in improving fluid absorption. In Crohn's disease, GLP-2 is superior to placebo in the induction of remission. Early data also suggest that the effects of GLP-2 on bone metabolism can provide a new treatment approach for patients with osteoporosis. In the future, the positive effects of GLP-2 on intestinal barrier function, splanchnic perfusion and mucosal healing could be utilized to expand its therapeutic application to other causes of intestinal injury. However, important safety aspects need to be considered when using this potent growth-promoting agent for a long term.
