Defecation refers to passing stool.painless dripping of blood during bowel movements is often considered to be caused by hemorrhoids, but it could also be due to anal fissures, anal fistulas, intestinal polyps, and other reasons, requiring prompt medical attention.
1. Hemorrhoids may be caused by prolonged sitting, which affects the venous blood circulation in the anal area, commonly resulting in anal swelling, itching, and post-defecation bleeding. Rubber band ligation can be used for improvement, followed by cleaning with potassium permanganate solution, physiological sodium chloride solution, or hydrogen peroxide solution for anti-inflammatory effects.
2. Anal fissures may be caused by chronic constipation or diarrhea, leading to mechanical trauma to anal tissues. During the illness, patients may experience periodic anal pain, sphincter spasms, and severe cases may result in anal bleeding after defecation. Treatments such as anal fissure excision and partial internal sphincterotomy can be used for recovery.
3. Anal fistulas may be caused by neglecting anal hygiene. During the illness, patients may experience pus discharge around the anus and anal itching, with severe cases potentially leading to secretion leakage. Treatments include fistula incision and anal fistula excision.
4. Intestinal polyps are polyps of varying sizes in the intestinal mucosa. As time goes on, their size may increase further, potentially leading to blood accumulation during defecation in later stages. Laparoscopic surgery is recommended for polypectomy. Additionally, it could also be caused by colorectal cancer, which may result in mucus or pus and blood in the stool. Without timely treatment, it may cause appetite loss and weight loss. Surgical resection of the lesion is needed promptly, followed by radiotherapy to inhibit the metastasis and spread of cancer cells.
