Overweight???????? Yep - have that problem too. Even in the most severe flares I don't loose any weight.
I found that mine is partially from genetics since most of my family is tall and big-boned. Most of the women in the family were overweight also. Bummer huh!
I found my weight gain began while I was pregnant, continued during the many stomach surgeries to complete the hysterectomy, gall bladder surgery and then the MC. I bloat right under my breasts mostly but the weight "roll" is in my lower abdomen. I look like I have two sets of
!!!!!!!! 
I try to watch what I eat to continue the weight loss (I've been maintaining within a few lbs but not "trying" to loose in the last few months) but it seems I'm just "watching" the food go from my fork/spoon to my mouth and then right down to the roll around my middle! Not funny - well............yes it is!!!!!!!!!!
gotta laugh instead of cry!I'm still holding out for the "magic pill" to take one night before bed and wake up in the morning at my "ideal" weight! Yea RIGHT!!!!
I know I've not been any help but I wanted you to know that you aren't alone and figured I'd try to make you laugh!
Hang in there sweetie - there's more of us out there!
Love,
