"What Else Besides Hemorrhoids Can Cause Rectal Bleeding?"

Blood in Stool

Blood in stool refers to the discharge of blood from the anus. Apart from hemorrhoids, other medical conditions can also cause rectal bleeding, such as anal fissures, colorectal polyps, ulcerative colitis, and gastric ulcers. It is recommended to visit the hospital's Proctology Department for a digital rectal examination, colonoscopy, and other tests to identify the underlying cause and receive appropriate treatment.

1. Anal Fissures

Anal fissures refer to tears or ruptures in the skin of the anal canal, often coexisting with perianal abscesses. Symptoms include rectal bleeding and anal pain, which can be described as sharp or tearing. Anal fissures often heal on their own, while patients with more severe symptoms may benefit from local application of medications like nitroglycerin ointment.

2. Colorectal Polyps

Colorectal polyps are growths originating from the epithelial lining of the colon and rectum. If a polyp ruptures, it can cause rectal bleeding, abdominal discomfort, and abdominal pain. Treatment involves endoscopic polypectomy.

3. Ulcerative Colitis

Ulcerative colitis is a chronic, non-specific inflammatory bowel disease characterized by recurrent diarrhea, mucous bloody stool, and abdominal pain. In severe cases, rectal bleeding may occur. Medications such as sulfasalazine enteric-coated tablets and olsalazine sodium capsules can be prescribed.

4. Gastric Ulcers

Gastric ulcers are a type of peptic ulcer, manifested by gastric pain, loss of appetite, postprandial bloating, and other symptoms. If the ulcer reaches the muscularis propria or serosa, rectal bleeding may occur. Treatment involves oral medications like omeprazole enteric-coated capsules and lansoprazole enteric-coated tablets.

In addition to the above, rectal cancer can also cause rectal bleeding, accompanied by abdominal pain, fatigue, and other symptoms. Surgical resection of the tumor, followed by radiotherapy and chemotherapy, is recommended. Furthermore, deficiencies in vitamin C, extreme obesity, and Crohn's disease can also lead to rectal bleeding, requiring individualized treatment plans based on specific circumstances.
