I've had an ultra sound and MRI and have a 10cm dermoid cyst that needs to be removed surgically. I'm experiencing bloating pretty much all the time.

I thought I had IBS. I've cut out so many foods from my diet-wheat, alcohol, fizzy drinks..even dairy because I was getting adult acne for the first time ever. I feel tired when I exercise-I go on long walks that are miles long to try to lose weight but trying to lose weight seems to make the bloating flare up more.

I went to a dietitian before the cyst was diagnosed-I was given loads of tips re bloating but I kept saying to her that it wasn't working, that I was still experiencing bloating and her hypothesis was that when I tried to lose weight, I cut out fibre so the bloating and constipation started again. It's more bloating now..my weight is 10st 3/8 in the morning, 10st5 7/8 by the afternoon and I'm so upset. I feel fat and bloated all the time, my body image has really suffered and I'm struggling to lose weight. My GP thinks it's IBS and prescribed this sachet that just made the bloating worse because it's so high in sodium (sodium is notorious for bloating). When I had my period one month, my weight literally went up 1 stone in a day due to bloat and it actually felt painful. 

I've had a blood test to see if it's cancer-I've been told it's unlikely but that it can't be confirmed until the cyst is biopsied after the operation so I'm worried that the bloating is a sign of ovarian cancer. I keep being fobbed off..can't get anyone to take my symptoms seriously and that just makes me more anxious and upset. Told my gynaecologist about the bloating..got no advice whatsoever about how to deal with it!

Any help/support would be greatly appreciated.

Thanks!
