Hey Chris, I just got my surgery last Wednesday! I am 180 pounds and 5'3". They said my colon was 7 or 8 pounds but after all that and not eating at the hospital much, I still weigh the same. HA go figure. I will tell you, I am so so so glad I had the surgery. I hurt like hell right now but getting better everyday. No regrets here and I wish you the best! I haven't had any problems with the bag yet either and I've got a big ol belly
