L Rachel,
you could wait to have the surgery until you are almost dead....or, until you can barely stand, feel like passing out every 15 minutes, in constant pain, nausea, etc., but that's your choice.
also, you said you have had three surgeries? Don't mean to scare you, but each time you have abdominal surgery, it does leave scars on the inside...the more scars you get, the harder it is to heal the next time.
Are you waiting for a cure? Are you waiting for some sign? are you on Prednisone a lot? If so, what do you think about
having cataracts at 40? Osteoporosis at 40? bags under the eyes at 40? Steroids induced diabetes at 40? If you're on Humira/Remicade/etc. - do you want to be on those biologics the rest of your life?
After you have the surgery, you are done - yeah, it's a long recovery - could take up to 24 months ( I don't know your situation), but you're done with UC, dirty bathrooms at car repair shops, running to the bathroom, going 65mph in a 25 zone trying to get home to go to the bathroom.....but, it's up to you.
Hope this helps, and sorry if I am a little blunt.
Best regards!!!
