My wife is 3 weeks out from surgery, has lost 47 pounds but has been having some issues as of recently. She started getting this severe pain in her right lower back/side, we think it could be constapation, she has went 3 times in the last 22 days, I ended up taking her to the ER and everything checked out normal from the blood work and cat scans. She has tried over the counter laxitives with no evail. She was originally losing 2 pounds a day, now she has gained 6 pounds, any ideas?

Has she tried an enema? She should be going more than what you state and if laxatives aren't working - that's what I would try. Has she called her surgeon?
