I had an polycystic ovarian cyst so I had an surgery 2 years back so my one ovary and fallopian tube is removed and now I am getting irregular periods and weight is also increased. Is there any risk. Will I again get a ovarian cyst. What will happen..

What will be will be. The best way to determine if there is a recurrence of the multiple ovarian cysts is to be examined by a GYN MD and have an ultrasound exam done. I can't predict the future, but the above advice will take of the present.
