this is a difficult question to answer as it will all depend on how things go. your friend may need to change some things initially during the recovery period. however there is a very good chance that she will have no long lasting effects from the surgery (though this somewhat depends on what part of the colon is going to be removed). i would recommend that your friend talk to her surgeon to be sure she knows what to look out for.
my friend is facing removal of about two feet of her colon and i was wondering what she can expect afterward?
