Why do I feel a tearing sensation in my anus during bowel movements, and see blood on the paper?

Anal tearing and blood on paper during bowel movements may be caused by constipation, hemorrhoids, anal sinusitis, and other reasons. If the body detects abnormalities, it is recommended to promptly visit a formal hospital and strictly follow the doctor's advice for treatment.

Constipation refers to a large intestine disorder characterized by difficult bowel movements and prolonged bowel movement time or intervals due to impaired conduction function of the large intestine. Patients experience reduced bowel movement frequency, dry and hard feces, which can scratch the local skin and mucosa when passing through the anus, causing pain, blood in stool, and other symptoms. It is recommended for patients to increase the intake of fiber and water in their diet, and appropriately consume coarse and miscellaneous grains. At the same time, good bowel habits should be established, with regular bowel movements.

Hemorrhoids can easily lead to obstructed venous return in the rectum, causing venous dilation, which can easily result in ruptured dilated veins, causing significant pain, often accompanied by bleeding symptoms. Treatment can be carried out with lactulose, magnesium sulfate, and other drugs under the guidance of a doctor.

After contracting anal sinusitis, inflammatory lesions may occur in the mucosal tissue surrounding the anal sinuses, causing symptoms such as anal fullness and pain. The pain symptoms intensify during bowel movements, and may be accompanied by purulent or bloody secretions. Treatment can be carried out with drugs such as oxycodone and acetaminophen, azithromycin, etc., as prescribed by the doctor. For severe cases, surgical methods such as anal sinus incision and drainage, and anal sinus resection can be performed.

In addition to the above reasons, anal tearing and blood on paper during bowel movements may also be caused by anal fissures, perianal abscesses, colon cancer, and other reasons. It is recommended that patients visit the hospital as soon as possible and receive targeted treatment based on the severity of clinical symptoms.
