While Gluconorm 500 (which contains metformin) is primarily a diabetes medication, it is also very commonly and effectively used to treat irregular periods, especially in those with Polycystic Ovary Syndrome (PCOS). Metformin helps by improving how your body handles insulin, which can balance hormones and restore a regular menstrual cycle, even if you do not have diabetes. It is a well-established and safe approach for managing these symptoms. I highly recommend discussing this with a healthcare provider to ensure it is the safest and most appropriate option.
