Doctors always told me this was normal after someone has bowel surgery. I found controlling the diarrhea with tincture of opium also slowed the bowels and reduced the sounds. I do still have issues sometimes with bowel sounds so loud other people take notice. When I have pouchitis, the bowel sounds are increased and more audible - one of the clues that’s what’s going on. Also, if I have to hold my bowels for a lengthy period of time, it becomes more noticeable so I try to use the restroom when I need to. I agree that gas can also be a part of this issue. I take Imodium also to help with sounds..
If you’re into holistic stuff, peppermint is good for upset stomach. Use it topically or with aromatherapy, even tea.
I’m not going to say that you have to just accept it, but sometimes it’s still noticeable and embarrassing at times. It helps motivate me to make sure I take my medicine. Especially at lunch time because bowel sounds are worse after eating. I pretty much plan a trip to the bathroom after eating.
