Thanks for the query.
You once go for a ultrasound
to find out the possible cause for delayed periods.
According to that you have to take the treatment.
If there is any possibility of poly cystic ovary disease, then in the early stages weight reduction can help to some extent in regularization of the cycles.
Decrease in weight can help in maintaining the hormonal
levels and there by regularization of the cycles.
