Hi doctor! My stomach has been full for over a week now. The doctor told me that having a full stomach for more than 1 week is a sign of what disease?

My mother has flatulence, her stomach is rumbling, she eats something strange and she goes out continuously. I went online to find out that it could be chronic colitis. Is it possible for my family to follow the use of a normal colon? Ask the doctor if bloating, abdominal bloating, continuous defecation is chronic colitis? I would like to thank you.
