Understanding Tenesmus

Tenesmus refers to the uncomfortable feeling of needing to have a bowel movement even when the colon is actually empty. This sensation can be associated with other symptoms, which may include cramping, pain, and, in some cases, rectal bleeding. The reasons behind tenesmus can vary widely, ranging from relatively benign issues like diarrhea or constipation to more serious conditions, including cancer.
