Blood in stool?

Not normal, get help: Blood in stool is a warning sign. Brisk bleeding warrants emergency care. Causes of bleeding may be predictable (e.G rectal trauma), but evaluation is always appropriate. A rule of thumb (but not absolute): black stool means bleeding comes from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anus.

Not normal: You need to be seen, evaluated and treated depending on the cause of the bleeding. See your doctor or a GI doctor. At 19 yo probably something simple like hemorrhoids, but better to be safe as not to miss something more serious.

Hemorrhoids: Most common cause is hemorrhoids. If you are over 50 or if you have a family history of colon cancer you should get a colonoscopy done to rule out colon masses, diverticulitis and ulcerative colitis.

Many causes: Blood in the stool is a diagnostic problem with many possible answers. Hemorrhoids the most common cause of small amounts of blood on the outside of the stool. In older folks, diverticuli can cause large amounts of fresh blood. Microscopic blood common in cases of colon cancer, many other causes possible. Bleeding ulcers can cause black/tarry stool. Best to get evaluated to find out for sure.

See below: The most common causes of blood in the stool are hemorrhoids and an anal fissure (tear in anus). Other causes include cancer, poyps, diverticulosis, angioectasia and colitis. Anyone with blood in their stool should discuss this with their doctor as further evaluation is necessary.

See doctor: Rectal bleeding is not normal and should always be evaluated. See a colorectal surgeon, who will do a complete evaluatin and examination, and can treat most causes of rectal bleeding.

Many possibilities: Broadly, bright red blood in stool comes from bleeding low in the GI tract (large intestine or rectum), or sometimes from rapid upper GI bleeding. Common causes include hemorrhoids and diverticulosis, with inflammatory bowel disease, colon cancer, and gastric ulcers being less common but more dangerous. Blood in stool should be evaluated by your doctor.

Possibly hemorrhoids: Most cases of rectal bleeding are from hemorrhoids. It should be evaluated for anything more serious though like colon cancer. See your doctor.

Many reasons: Potentially but most common is hemorrhoids, fissures, fistula but less frequently infection or colitis/proctitis, polyps, tumors. No amount of bleeding is normal regardless of the cause. See a colorectal surgeon promptly to identify and treat the cause before more serious problems develop.

Many answers: There are many causes of blood in the stool. Some like rectal fissure or hemorrhoids are uncomfortable but are generally benign. Others like cancer or inflammatory bowel disease generally carry a more serious prognosis. Either way, if you have blood when you have a bowel movement (bm), you should see a doctor for further evaluation.

Get checked out.: For most people, the most common cause of blood in the stool is caused by hemorrhoids or anal fissures. However, we take it seriously because colon and rectal cancers can also cause blood in the stool. I tell my patients, especially if they're over 50 or have a strong family history of colon cancer to get it checked by a doctor just to be on the safe side. Hope this helps!

Get checked: Blood always needs an explanation, but is also common to many benign problems, like hemorrhoids, anal fissures and overall irritated lower GI tract for many possible reasons. However, it is also probably the most reliable sign of serious problems, cancer being one of them, so go and get checked!

See a doctor: Blood in the stool is never "normal". However, most of the time it is not serious - hemorrhoids (swollen anal veins) are the most common cause. Warm baths with epsom salts and a mild cream like anusol can help those. However, blood in the stool may be indicative of a colon polyp or tumor or inflammation of the colon. If it is persisting you should see a doctor for an examination. Peter wilk, md.
