Do hemorrhoids block stool?

Hemorrhoids, which are swollen veins in the rectum or anus, can cause pain, itching, and discomfort, but they typically do not block stool. However, they can make bowel movements more difficult and painful, which can lead to constipation or straining during bowel movements. In rare cases, a large hemorrhoid or a blood clot within a hemorrhoid can obstruct the anus and make it difficult to pass stool. If you are experiencing difficulty passing stool or have concerns about your hemorrhoids, it is important to consult with a healthcare provider.
