Who is the study for?
This trial is for young people aged 8-21 with Type 2 Diabetes who speak English or Spanish. They must be able to wear a CGM device for 6 weeks, have been on a stable medication regimen for at least two weeks, and take regular metformin. Those with significant mental illness, ongoing renal or hepatic disease, or pancreatic autoantibody positivity cannot participate.
What is being tested?
The study is testing the effects of two different doses of metformin in youth with Type 2 Diabetes: the standard dose (1000mg twice daily) versus a higher dose (1350mg twice daily). Participants will compare these dosages over the course of the study.
What are the potential side effects?
Metformin can cause side effects like stomach upset, diarrhea, nausea and vomiting, gas, weakness, headache, muscle pain and low blood sugar levels. The risk may increase slightly with higher doses.
