-Visual confirmation of hemorrhoids can be done by doing an [[anoscopy]], using a medical device called an anoscope. This device is basically a hollow tube with a light attached at one end that allows the doctor to see the internal hemorrhoids, as well as polyps in the rectum.

-If warranted, more detailed examinations, such as [[sigmoidoscopy]] and [[colonoscopy]] can be performed. In sigmoidoscopy, the last 60cm of the [[colon (anatomy)|colon]] and rectum are examined whereas in colonoscopy the entire bowel is examined.
-A pathologist will look for dilated vascular spaces which exhibit thrombosis and recanalization.
