Diagnosis
A visual analysis of your anus can be adequate to diagnose external hemorrhoids. In order to confirm the diagnosis, the physician may perform various examinations to check out any abnormality or defect around the anus. This verification is done through a digital rectal exam. While performing this test, your physician inserts a well lubricated and gloved finger in your rectum. If a doctor feels something abnormal, he can ask for an additional test known as sigmoidoscopy.
A sigmoidoscopy is a method involving a tiny camera to view inside the rectum and verify internal hemorrhoids. The small camera known as sigmoidoscope is fitted within a narrow tube and then it is inserted within your rectum. Your doctor gets a visible and clear view of the inner part of your rectum by this test so that he can analyze hemorrhoids clearly.
