Hi, thanks for using healthcare magic
One of the common causes for irregular periods
is PCOS which stands for polycystic ovarian syndrome
This condition is associated with irregular periods,infertility,polycystic ovaries
, abnormal hair growth, acne, insulin resistance
It commonly occurs in women who are overweight, weight loss helps in this condition and may regularise the periods and increase chances of conception in women trying to conceive.
One of the medications commonly used is the glycomet that you mentioned. It would reduce the insulin resistance and help with weight loss.
It is effective and safe
Hope this helps
