Jingle,
If you read my signature, I have had several major organs removed. I honestly did not feel any different after any of the surgeries, there was no empty feeling, the other organs just adjust to take up the empty space.
I hope this makes you feel a little more comfortable about the whole thing. I wish you the very best and just want you to know that although I didn't have mine removed from UC, it was the BEST decision that I ever made; I am so healthy now and have never felt better!!!!
Judy
