I am 21 years old, female. I have always had healthy bowel movement, once or twice daily, hardly constipated. They would always come out in one or two thick pieces in brown to light brown colour. From the past one year I have been noticing some changes in the movement. I no longer get the thick pieces, instead they are either in small chunks or are pencil-like, flat and smoothish. Sometimes I feel there is more but nothing comes out. Throughout the day I feel slight discomfort around the area, though it is not severe.
Can there be any obstruction that is causing these symptoms? I have not experienced blood with my stool but my brother once had a polyp in his colon with similar symptoms so I thought of medical advice.
I would appreciate any opinion.
