What causes bleeding in stool before menstruation?

1. If bleeding occurs occasionally and the blood is bright red, or there is blood on toilet paper, especially if blood in the stool occurs after passing hard stool, it may be hemorrhoidal bleeding.

2. When the patient is constipated, coughs, sits for a long time, or women are pregnant, the abdominal pressure increases, which can cause the venous masses to rupture and bleed. Bleeding first and then defecation during bowel movements is mainly related to hemorrhoids.

Is dry, painful, and bleeding stool caused by hemorrhoids or anal fissures?

1. Bleeding caused by hemorrhoids is generally painless. If the above situation is caused by anal fissure, the patient needs to keep the bowel movements unobstructed. You can consider taking some oral laxatives to relieve dry stools. You should also drink plenty of water, develop a good habit of regular bowel movements, and eat more fresh vegetables and fruits rich in dietary fiber.

2. When the patient's abdominal pressure increases, the patient's intestinal mucosa will be easily scratched during the defecation process, resulting in blood in the stool. In addition, the muscles of the perianal mucosa will be damaged, resulting in anal fissures. Dry and bleeding stools and anal pain are common in anorectal diseases such as anal fissures and hemorrhoids.
