Hi Katerina,
My advice is go into this with your eyes and ears wide open. A pouch is not a given route to endless happiness. I've had mine for 3 years and it's no bargain. Yes, it's better than an ileostomy in many ways, particularly from a lifestyle/ relationship viewpoint if that is important to you but it comes with strings attached. It's NOT a colon and so your hopes of 4 visits to the loo per day and 2 at night are not unrealistic but as many who post on here will attest it could be 2 times a day and once at night or, as is my experience, 8-10 times a day and twice at night. Sometimes the need to go is strong, other times it isn't. Diet is very important but getting good advice on diet is, in my experience, very difficult. In the UK, where I am, you are told that you can eat what you like but when problems arise then the advice changes! No two people are the same. A pouch is, in my opinion , a life changing surgery that will have life long consequences. The option not to have a colectomy probably doesn't feature for you but you need to know what's heading your way..I'm not at all unhappy that I've had the surgery but sometimes, in my experience, surgeons and physicians tend to " sugar coat" the procedure and the outcome. Do .ots of research, ask lots of questions and get it straight in your head what is happening to you.. Good luck !
