Wanting a tummy tuck but have terrible IBS and bloating.

You have a real concern and I would encourage your talking to your gastroenterologist before having anything to increase your intraabdominal pressure. While I don't think your IBS will be worse (I've operated on several patients with IBS who had no problems postop), I would be concerned about limiting your intraabdominal capacity, potentially raising your diaphragms and making your breathing more difficult. Of course, another option would be remove the loose skin but not plicate your abdominal wall.  This would remove the skin you don't like but not risk worsening your breathing.

Far more important than deciding if TT is for you is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let him explain why one technique may be better than another and if you need a tummy tuck. Many board certified plastic surgeons provide a free first time consult and you should take advantage of that! See the below link on some suggestions on finding the most qualified Plastic Surgeon for you!

Thank you for your question.  I m sorry to hear about your IBS.  You will need clearance from your GI physician before surgery.  Consult with a board certified plastic surgeon.  Best Wishes
