Bleeding from the stool is alarming but may be caused by an unimportant condition or a fatal disease. Isolated stains are usually the result of haemorrhoids or fissures. Still, frequent or copious bleeding, particularly with pain or loss of weight, must lead to medical consultation to exclude infection, polyps, or bowel cancer of the gastrointestinal tract.
What Causes Blood in Stool?
Stool blood may be secondary to haemorrhoids, anal fissures, diverticulosis, inflammatory bowel disease (IBD), infection, or colorectal carcinoma. It may also result from gastrointestinal bleeding due to ulcers or certain medications. The quantity and color of the blood may provide information about the location and severity of the pathology.
What Does Blood in Stool Look Like?
The color of the blood in the stool is unpredictable and provides valuable information regarding the location of the bleeding:
- Fresh Red Blood: Usually indicates that the bleeding is from the distal GI tract, e.g., rectum or anus.
- Dark Red or Maroon Color of Blood: Indicates that the source of bleeding is higher up in the small intestine or large colon.
- Melena (Tarry or Black Stool): Usually points to bleeding in the upper GI tract, like the esophagus or stomach. After passage through the intestines, the blood is digested and thus darker.
Regardless of whether the blood is seen on the toilet paper, mixed in with the stool, or colors the entire stool, caution should be exercised and consideration given to seeking medical assessment.
What Are the Common Causes of Blood in Stool?
A few of the common causes are:
- Hemorrhoids: Hemorrhoids, or inflamed veins in or around the anus or rectum, are a frequent cause of blood in stool. Hemorrhoidal bleeding is often bright red and can be seen on the toilet paper or be visible as it drips into the bowl. Hemorrhoids are usually due to constipation, straining at a bowel movement, or prolonged sitting.
- Anal Fissures: Anal fissures are small, painful tears in the skin around the anus. They may result in bright red blood on the stool or toilet paper. Straining to move hard or large stools, constipation, or diarrhea are the most common causes of anal fissures. Anal fissures are not serious, although they hurt. They can heal with normal care and hydration.
- Gastrointestinal Infections: Infections in the gastrointestinal tract, including bacterial infections by Salmonella or Escherichia coli (E. coli), can cause bleeding in the stool. The symptoms can also come along with diarrhea, abdominal pain, and fever.
- Inflammatory Bowel Disease (IBD): Stool blood may also be indicative of inflammatory bowel diseases like Crohn's disease or ulcerative colitis. They are chronic diseases that cause inflammation of the intestines, the creation of ulcers, and bleeding. The blood would be dark or tarry in color if it came from a more proximal site in the gut.
- Colorectal Polyps or Cancer: Occasional bleeding at times can be due to colorectal polyps or cancer. Polyps are benign growths in the colon that may bleed, and bleeding during stool may be due to colorectal cancer when the disease reaches an advanced stage. Early diagnosis is essential, and screening by colonoscopy is advised for adults starting at age 50.
- Diverticulosis and Diverticulitis: Diverticulosis is the growth of small pouches in the lining of the colon, and when they become inflamed or infected, they bleed—a condition known as diverticulitis. The bleeding can be minimal or heavy, and it can be accompanied by abdominal cramps, fever, and alterations in bowel habits.
- Peptic Ulcers: Stomach or upper intestine ulcers, often the consequence of Helicobacter pylori infection or the prolonged use of NSAIDs, can cause bleeding. Bleeding manifests as black, tarry stools, thus defining its source in the upper GI tract.
- Esophageal Varices: Esophageal varices, which are dilated esophageal veins that often result from liver disease, can bleed and cause severe bleeding. It's a condition that needs immediate medical treatment.
- Anal or Rectal Trauma: Trauma to the rectum or anus, like straining too hard or inserting a foreign body, can cause bleeding. While minor trauma can resolve on its own without the need for medical evaluation, more severe trauma can necessitate a doctor visit.
What are the Symptoms to Watch For?
Some of the symptoms associated with blood in stool can provide clues regarding the severity of the incident. They include:
- Chronic Pain: Abdominal or rectal pain persisting over a long period may be a sign of a dangerous condition.
- Stool Color Change: Bright red blood from the lower gastrointestinal tract can be presumed to originate from this region. Dark or tarry blood most often indicates upper GI bleeding.
- Unexplained Weight Loss: Unexplained weight loss is often a sign of colorectal cancer or an equally dangerous illness.
- Dizziness and Fatigue: These can occur with chronic anemia due to blood loss.
- Fever or Chills: Bleeding due to infection can manifest as fever or chills.
When to Seek Medical Attention
Although intermittent blood in the stool due to minor causes is not always an indication for emergent therapy, there are specific conditions for which one should seek treatment. If:
- Bleeding continues or is excessive.
- Bleeding is black or tarry, or it's mixed with stool.
- You have other signs like extreme abdominal pain, fever, or unintended weight loss.
- Gastrointestinal cancer or chronic diseases like IBD run in the family.
- Age of more than 50 and no regular screening for colon cancer.
Diagnostic Procedures
When you see a medical practitioner for stool blood, the physician will first perform tests to determine the cause. They include:
- Physical Examination: Your physician can inspect the area around the anus and rectum for hemorrhoids or fissures.
- Stool Tests: Samples will be examined for infection, blood, or other irregularities.
- Endoscopy: Tests like colonoscopy or sigmoidoscopy enable physicians to see inside the rectum and colon to seek out conditions like cancer or polyps.
- Imaging Tests: CT scans or MRI can be used to reveal conditions in the digestive tract.
- Blood Tests: Blood tests may screen for anemia and other indications of internal bleeding.
Preventive Measures
Prevention of the causes of stool blood is vital to overall digestive health. Implement these life changes:
- High-fiber Diet: Fruits, vegetables, whole grains, and legumes prevent constipation and minimize the risk of hemorrhoids and fissures.
- Proper Hydration: Proper fluid intake keeps stools soft and comfortable to pass.
- Exercise Regularly: Regular exercise enhances digestive function and bowel movements.
- Minimal Sitting: Frequent physical activity can relieve pressure on the rectal veins.
- Restrict NSAID Use: Limit the use of nonsteroidal anti-inflammatory drugs to avoid stomach ulcers.
FAQs
Q: Is All Blood in the Stool a Sign of Cancer?
A: No. Colorectal cancer is one potential cause, but most instances are caused by less severe conditions such as hemorrhoids or fissures. Nevertheless, it is necessary to get checked out.
Q: What Does Bright Red Blood in Stool Generally Mean?
A: Most often lower tract bleeding is bright red, so very likely it's bleeding due to hemorrhoids, anal fissures, or the rectum.
Q: When Do I Have to See a Doctor About Blood in My Stool?
A: If bleeding continues, is heavy, painful, accompanied by bowel habit change, weight loss, or fatigue, go see a doctor.
Q: Is Black Stool Ever a Cause for Alarm?
A: Black tarry stool may be a sign of upper GI bleeding and should be investigated at once if it is recurrent or accompanied by dizziness or weakness.
Q: Does Stress Cause Blood in the Stool?
A: Stress will exacerbate symptoms of IBS, but is not likely to cause bleeding. Blood in the stool will always need to be investigated by a physician.
Q: How Is Blood in Stool Diagnosed?
A: Diagnosis can be a rectal examination, stool tests, colonoscopy, or imaging based on history and symptoms.
