I had some problems post surgery also. It takes awhile for things to simmer down. I have a permanent ileo, so only one surgery. What is your diet like? Gatorade, for some reason or other, did a number on me. It gave me terrible diarrhea and then I started vomiting. This was about six weeks post op. I wound up back in the hospital with dehydration and low electolytes. That is the reason I drank the darn stuff, because it was to replenish electrolytes .
I still have noises, but they only come at night when watching tv. It's like the stoma wants attention or something.
I don't take any probiotics. I had my fill of them when I suffered with UP (proctitis) and they didn't seem to help me at all. But others take them, so guess they are ok. I just take daily vitamins and calcium with D.
