Study summary

This study is being done to compare the effect of regular exercise and metformin in people who have prediabetes. It is a community-based, open-label, randomized trial in which eligible participants will be divided into two groups. One group will do moderate physical exercise, and the other group will take metformin for 12 weeks. We will check their fasting blood sugar and HbA1c before and after the treatment to see which method works better for controlling sugar levels. The study is being done in a low-resource community setup to see which option is more practical and effective in real-life Pakistani settings.
