Why would i have a colonoscopy when anemic?
8 doctors weighed in across 3 answers
Colon cancer: One of the most common causes of anemia in adults is colon cancer. In this type of cancer, one can slowly bleed over many months slowly making him/her more anemic. If a small cancerous polyp is found early, it can be removed and the cancer treated before it spreads. That is why a colonoscopy is recommended in unexplained cases of anemia.

To find the reason: To see if a lesion in your colon is the reason for your anemia. Large polyps and cancers can bleed slowly in the colon leading to anemia.

Looking for cause: Your doctor is looking for a reason for your anemia and one possibility is that you have been bleeding from your GI tract without noticing it. There are multiple causes for this ranging from benign to cancer.
