1What it is
GLP-2 is a 33-amino-acid hormone cut from the same proglucagon precursor as GLP-1 and oxyntomodulin and released by L cells in the ileum and colon after meals. Where GLP-1 manages blood sugar and appetite, GLP-2 looks after the gut itself: it is the main hormonal signal that tells the intestinal lining to grow and adapt. After bowel resection the remaining gut normally undergoes "adaptation" partly driven by GLP-2 — but people whose terminal ileum and colon have been removed lose most of their L cells and therefore most of their GLP-2.
Teduglutide is GLP-2 with a single amino-acid swap that protects it from DPP-4, extending its from minutes to about two hours. It was developed by NPS Pharmaceuticals (later Shire, now Takeda) and approved in 2012 for adults with short bowel syndrome (SBS) who depend on parenteral support — intravenous nutrition or fluids. The pediatric indication followed in 2019 (US) and the EU extended it to infants from 4 months †. Community/self-directed use: essentially none documented; the drug is expensive, specialist-initiated and has no plausible use outside intestinal failure.

Long-term use and weaning off parenteral nutrition
Children with SBS
Other indications
Next-generation GLP-2 analogues
4Reported side effects and interactions
Literature-reported
Common (literature). abdominal pain (~30–38%), injection-site reactions, nausea, abdominal distension, headache, upper respiratory infection, vomiting; in people with a stoma, swelling or enlargement of the stoma is very common (~40%) and may require refitting.
Serious / warnings (label). acceleration of neoplastic growth — colonoscopy of the whole colon with polyp removal is required before starting, after one year, then at least every five years; contraindicated with active GI malignancy and not recommended with any active non-GI malignancy; intestinal obstruction (sometimes requiring dose interruption); gallbladder, biliary and pancreatic disease (cholecystitis, cholangitis, pancreatitis — check bilirubin, alkaline phosphatase, lipase and amylase before and during treatment); fluid overload and heart failure as absorption improves and parenteral volumes lag behind.
Community-reported
none documented.Interactions. improved absorption can raise blood levels of oral medicines with a narrow therapeutic window (e.g. benzodiazepines, antiepileptics, warfarin); doses may need adjusting as the gut recovers. Antibodies to teduglutide develop in a minority and have not been linked to loss of effect.
Markers researchers commonly monitor
These follow the label and intestinal-failure practice:
| Marker | Why it's watched |
|---|---|
| Parenteral support volume and days per week | the primary efficacy measure; adjusted downward in steps as urine output rises. |
| Urine output and body weight | the first signs that absorption has improved; also the early warning for fluid overload. |
| Electrolytes, magnesium, phosphate, renal function | shift as parenteral volumes are cut. |
| Bilirubin, alkaline phosphatase, lipase, amylase | at baseline and every 6 months for biliary and pancreatic warnings. |
| Colonoscopy | before starting, at one year, then at least every five years (sooner if polyps found). |
| Plasma citrulline | a research marker of enterocyte mass; rises with teduglutide. |
| Drug levels of narrow-window oral medicines | because absorption improves. |

5Reconstitution and handling
Supplied as a kit of 5 mg vials with prefilled 0.5 mL syringes; after the solution is 10 mg/mL and the weight-based dose (0.05 mg/kg) is drawn up in a 1 mL syringe — e.g. 3.5 mg (0.35 mL) for a 70 kg adult. Inject once daily into the abdomen, thigh or arm, rotating sites; use within 3 hours of mixing. Patients are trained by their intestinal-failure team. The site calculator is not needed for the approved product.
6Commonly studied alongside
Semaglutide and other GLP-1 analogues (same proglucagon family, different job — GLP-1 agonists have also been explored in SBS to slow transit), oxyntomodulin, apraglutide and glepaglutide (investigational longer-acting GLP-2 analogues), somatostatin analogues such as octreotide (used in high-output stoma), growth hormone (somatropin, previously approved for SBS in the US as Zorbtive).

8Open questions
- Does long-term GLP-2 agonism increase colorectal cancer risk in people, or is the signal confined to animal models?
- Which patients will achieve full independence from parenteral nutrition, and can treatment ever be stopped without relapse?
- Will once-weekly analogues match teduglutide's effect with better adherence?
