How to distinguish between anal fissures and hemorrhoids
To distinguish between anal fissures and hemorrhoids, one can first differentiate based on symptoms. Anal fissures primarily cause pain during defecation and minor bleeding, with the pain typically lasting from 20 minutes to half an hour. Patients often have hard stools or constipation. In contrast, hemorrhoids primarily lead to intermittent painless rectal bleeding. The blood is bright red and usually in greater volume, often appearing in a spraying or dripping pattern after defecation. Some patients may also experience prolapsed hemorrhoids, often accompanied by a sensation of heaviness and foreign body in the anus. Further, through a digital rectal examination, an anal fissure can be identified by a palpable ulcer or crack at the posterior or anterior midline of the anus. Hemorrhoids, being soft venous clusters, can also be differentiated through this examination.
