Causes of rectal bleeding in Minnesota

Rectal bleeding refers to the passage of red blood from the rectum and anus, often mixed with stool and/or blood clots. The severity of rectal bleeding varies widely. Most rectal bleeding is mild and intermittent, but it also may be moderate or severe.

Rectal bleeding can be caused by various conditions, but even the slightest amount of bleeding should be taken seriously. Common causes of bleeding are internal hemorrhoid, ruptured thrombosed external hemorrhoids, fissures, diverticulosis, colon cancer, colitis, polyps and angiodysplasias. Patients of older age or with significant family history of bowel disease or cancer should consider further examination. In addition, patients who were previously treated for rectal bleeding but continued to experience bleeding must be further examined.

Many patients in the Minneapolis and St Paul areas think rectal bleeding is always caused by hemorrhoids. When these patients come to the doctor’s office because of rectal bleeding, they tend to say they have hemorrhoids. The notion that rectal bleeding is the same as hemorrhoids is dangerous, as this may lead to a delayed diagnosis and treatment. The truth is that rectal bleeding in some patients could be caused by colon cancer with or without hemorrhoids.

The source of rectal bleeding is determined by history, physical examination and blood tests, assisted with anoscopy, sigmoidoscopy, colonoscopy, radionuclide scans, and angiograms.

Treatment of rectal bleeding includes correcting the low blood volume and anemia, determining the site and cause of the bleeding, and stopping the bleeding.
