Hello, Borislav.
The sounds from your intestines could be because of the operation because you didn't have them before the operation. Or, maybe you did have sounds before your operation but not so loud and you did not notice the sounds as much, but since your operation you are paying very close attention to everything that happens. You don't have a colon anymore so food and gas are moving through you in a shorter time,mould be the reason for loud noises. The adult colon is approximately 5 feet long, so that is a lot of space before to hold food, gas, and now you don't have the colon space anymore. I don't know if it will stop after more time. You are still new with the pouch. Give it some more time for your intestines to adjust. If there is no pain, blood, fever, discomfort, blockage, and you are eating and pooping regularly, can you wait and ask your doctor when you have your appointment in a few months? If it is causing you trouble or upsetting, try to reschedule your appointment sooner to get answers. My stomach (or intestines, not sure which) makes gurgling and whooshing sounds after I've eaten, or even when it has been hours since I ate. All the time, but not too loud for me.
