Rectal Bleeding: This can be a sign of polyps, but it's also a symptom of other conditions like hemorrhoids or colorectal cancer.
Change in Stool Color: Polyps can cause dark or black stools if there is bleeding into the digestive tract. The blood can also make stools look tarry.
Change in Bowel Habits: New constipation or diarrhea that lasts more than a few days may indicate the presence of a larger colon polyp or other condition.
Iron-Deficiency Anemia: Unexplained anemia might be caused by bleeding from a polyp.
Abdominal Pain or Cramping: Large polyps can obstruct the bowel and cause abdominal pain or cramping.
Nausea or Vomiting: If a large polyp blocks part of the colon, it can lead to nausea, vomiting, and severe constipation.
Feeling that the Bowel Does Not Empty Completely: This sensation can occur with colon polyps, although it's also common in other conditions.
Mucus in Stool: Seeing mucus in the stool can be a sign of polyps, but like other symptoms, it's not exclusive to them.
