Glucagon-like peptide 2 (GLP-2) is primarily used in medical applications to promote intestinal growth and function. It is particularly beneficial for patients with short bowel syndrome, as it enhances nutrient absorption by increasing the surface area of the intestinal lining. GLP-2 also helps reduce the frequency of parenteral nutrition dependence, improving the quality of life for affected individuals. Additionally, it has shown potential in treating conditions like Crohn's disease and other gastrointestinal disorders by supporting mucosal repair and reducing inflammation. Its therapeutic effects make it a valuable tool in managing intestinal insufficiency and related complications.

However, the use of GLP-2 must be under close medical supervision due to potential side effects such as increased intestinal tissue mass or risk of tumor development in some cases.
