Hello, my husband had part of his colon removed about 8 years ago due to diverticulitis. He had a colostomy bag for about a year after the surgery. After his second surgery to remove the colostomy, the left side of his stomach is rounder and bigger than the right side. He doesn't have any discomfot and his bowel movements are normal, but as I see the left side of his stonach getting larger, I am getting more and more concerned. Is this distension normal or is there something to worry about? He says its just because he's gaining weight, but I'm not so sure. Thanks!!
