GLP-2 analogs, such as teduglutide, and fusion proteins of GLP-2 with immunoglobulin are administered before, during or after surgery, particularly resection of the small intestine. When short bowel syndrome develops after surgical resection of the small intestine, parenteral nutrition is usually necessary to compensate for reduced absorption of water and nutrients across the small intestine. GLP-2 analogs and GLP-2 fusion proteins promote growth of small intestine, improve nutrient absorption and can reduce the need for parenteral nutrition after surgery.
