They may be benign (e.g. hyperplastic polyp), pre-malignant (e.g. tubular adenoma) or malignant (e.g. colorectal adenocarcinoma). • • Colorectal polyps are not usually associated with symptoms.[2] When they occur, symptoms include bloody stools; changes in frequency or consistency of stools, such as a week or more of constipation or diarrhoea;[3] and fatigue arising from blood loss.[2] Anemia arising from iron deficiency can also present due to chronic blood loss, even in the absence of bloody stools.[3][4] Another symptom might be increased mucous production especially those involving villous adenomas.[4] Copious production of mucous causes loss of potassium that can occasionally result in symptomatic hypokalemia.[4] Occasionally, if a polyp is big enough to cause a bowel obstruction, there may be nausea, vomiting and severe constipation.[3]
