Symptoms Of A Tubular Adenoma

Rectal Bleeding

The most commonly reported symptom related to tubular adenomas is rectal bleeding, which often shows up on toilet paper or in the underwear as dark red or black. Because of the way the polyp projects inward into the colon, when stool moves through the colon it produces friction between the two surfaces. If bowel habits are somewhat normal, this friction is happening at least twice a day, every day. Eventually, the tubular adenoma starts to accumulate surface abrasion that causes intense irritation and leads to the bleeding of small capillaries that lie just under the surface of the intestinal lining. Additionally, the polyp itself can cause the stool to slow or even stop because it is obstructing the path, which leads to very hard stools that frequently cause bleeding in the colon even in individuals who do not have a tubular adenoma. The compounding of very hard stools and an already inflamed tubular adenoma can cause significant internal bleeding that sometimes can go unnoticed. Complications such as iron deficiency and hypovolemic shock can result from internal bleeding that goes unaddressed.
