Hi, Borislav.
Some specialists and surgeons are very booked with appointments so maybe it is hard to find room or move you sooner. I'm sorry about that. It is hard to wait for answers.
For now, write a list of your questions and concerns. Have them ready to ask your surgeon in September, or give your list of questions to your surgeon before they put you to sleep and ask them to write down their answers. Read their answers when you wake up. If they say your pouch problems are all normal and don't worry, tell them specific things that have been disturbing you and please give you a definite answer.
Your pouch is still new. Try not to worry. Intestines and pouches do not like stress, and you can't digest food properly if your intestines are tight with worry. As long as you are not in pain, bleeding, blocked, or fever. My pouch took 9 months before it stopped giving me problems. At 10th month I could eat food and go out without too many problems. I hope sooner for you.
