Thanks for the comments. I had my surgery last monday. I had the open procedure done to preserve my ovary. It wasnt as bad as I thought it was going to be. I was in the hospital until weds. Since the surgery my stomach had been really swollen and loose (its so huge). I look pregnant and I cant even imagine trying to wear jeans. I had my one week check yesterday and have lost 9 pounds since even though I dnt feel like it the surgery so maybe the cyst does cause weight gain. My cyst was small and was not ruptured so im not sure why it caused me so much pain.
Good luck with your surgery also!!!!
Im in almost the same boat as you, same age, and due to have surgery for an ovarian cyst. I have no pain, yours must have twisted or ruptured? Im in plenty of discomfort though and look 4-5 months pregnant, with next to no information from my doctors. Woho.
Your current medication may make you gain weight, where is the weightgain? Change your metabolism? Is it firm or floppy?
If it is your cyst growing, it will go on your belly, and being a sack full of liquid (or whatever it might be in your case) it will be quite firm and make you look bloated/pregnant. If that is the case with you, the surgery should cure it by removing the cyst(s).
I have not experienced any other weight gain, but you should mention it to your doctor, they may be able to change your medication if that is the cause.
The tiredness and bowel movement could also be caused by the cyst, I am struggling with both myself. As far as I can understand the surgery will cause the same symptoms due to the anesthetics and stress on your body, so it would take a while for you to know if they stop when the cyst is gone.
Good luck!
im not good with this, but im guessing it might all stop and you should get back on track, before the surgery ask the nurse and see what there answer is, good luck
