Metformin Cuts Insulin Use in Type 1 Diabetes
18 Apr
Summary
- Metformin study involved 40 adults with long-term type 1 diabetes.
- Drug did not reduce insulin resistance but lowered daily insulin use.
- Patients on metformin used 12% less insulin daily for stable blood sugar.
A recent study explored the potential benefits of metformin for individuals diagnosed with type 1 diabetes. The INTIMET trial, involving 40 adults with established type 1 diabetes, investigated the drug's effects over a six-month period. Participants continued their standard insulin regimens, with one group receiving metformin and the other a placebo.
Unexpectedly, the study revealed that metformin did not reduce insulin resistance in participants. However, a significant finding was that those who took metformin used about 12% less daily insulin. This occurred while their blood sugar levels remained stable, suggesting a new avenue for managing type 1 diabetes.
Researchers are now investigating how metformin achieves this effect, with theories pointing towards its impact on the gut microbiome. This discovery could lead to a less burdensome management of type 1 diabetes by potentially decreasing reliance on insulin injections, a treatment that carries significant physical and mental tolls.
