Hello First of all read this carefully , thereafter I try to answer your question. PCOS ( pcod ) i.e . Poly Cystic Ovarian Disease or Syndrome is very common now a days in young child bearing age group female . Reason is not known , why so common. Having these symptoms. Androgen excess. Menstrual irregularities , dysfunctional uterine bleeding or amenorrhea ( no bleeding or only spotting ). Obesity with glucose intolerance. Alteration of LH/FSH ratio. Elevated serum testosterone level. Ultrasound changes in ovaries or ovary . You are taking ebxid, oosure and metformin( glycomet ) , these are drug of choice for the treatment for PCOS . Irregular bleeding or heavy bleeding or dysfunctional bleeding are due to PCOS. This type of bleeding is not the side effects of various medicine . Cysts are often caused by hormone changes. Using these drugs can some times help regulate hormone levels so that the cysts can be taken care of . Your gyne will likely want you to come back after you have been on these drugs to see if the cyst is gone. At that time she will decide future course of action ,so take these drugs as advised your doctor. Good luck.
