How does metformin work?
Metformin lowers glucose production in the liver and helps the body use insulin more effectively. This reduces blood sugar levels and improves overall diabetes management.
What is metformin used to treat?
Metformin is commonly prescribed for:
- Type 2 diabetes (to help manage blood sugar levels)
- Polycystic ovary syndrome (PCOS) (sometimes used to regulate hormones and insulin resistance)
