No abdominal pain but bleeding from the anus

Under normal circumstances, rectal bleeding without abdominal pain may be caused by hemorrhoids, anal fissures, anal polyps, or other factors. Patients can receive symptomatic treatment based on the specific cause. Detailed analysis is as follows:

1. Hemorrhoids

Hemorrhoids develop due to dilation and varicosity of the venous plexus around the rectum or anus, leading to slowed blood flow. This condition causes congestion and swelling of blood vessels inside the anus, which are prone to rupture and result in rectal bleeding without abdominal pain. It is recommended that patients use medications such as GuanTai ointment or Yunnan Baiyao hemorrhoid ointment under medical guidance, while also developing healthy bowel habits.

2. Anal Fissure

An anal fissure refers to a tear at the junction between the rectum and anus. Excessive straining during defecation, contraction of the anal sphincter muscle, or infection may lead to anal fissures, causing symptoms such as abdominal pain, a burning sensation in the abdomen, and bloody stools. It is recommended that patients use medications such as Huazhi capsules or Dijincao capsules under medical supervision, and avoid excessive straining during bowel movements.

3. Anal Polyps

Anal polyps are mucosal growths in the anus that resemble mushrooms. Local mucosa exposed to inflammatory irritation may develop polyps, which can bleed when irritated by friction or traction. It is recommended that patients use medications such as Maren pills or lactulose oral solution under medical guidance, and increase fluid intake.

Besides the three causes mentioned above, other conditions such as Crohn's disease, colon cancer, or anal cancer could also be responsible. Patients are advised to seek timely medical evaluation and treatment.
