Blood in the stool is generally not a sign of a serious illness, though it can be unsettling. In many cases, it may result from common issues like piles, constipation, or minor anal tears. However, rectal bleeding can also indicate more concerning conditions such as infections, inflammatory bowel disease (IBD), or colorectal cancer. That’s why it’s crucial to identify the cause early and seek appropriate medical advice.
If you’re in Hyderabad and need expert guidance, consulting a gastro surgeon or proctologist is a wise choice. Laserqure is a trusted name in the city, offering specialized care for rectal and gastrointestinal conditions. In this blog, we’ll explore when blood in the stool becomes a concern, its potential causes, and how rectal bleeding specialists in Hyderabad can assist.
What Does Blood in Stool Look Like?
Blood in stool might reveal important information about the bleeding source based on its appearance and colour.
Bright red blood typically points to bleeding in the lower gastrointestinal tract, such as the rectum or anus. It can be found on the stool’s surface, in the toilet bowl, and on toilet paper. Anal fissures or haemorrhoids are frequently linked to this kind of bleeding.
However, some foods—like beets, tomatoes, or items containing red food coloring—can also cause the stool to appear red, which may be mistaken for blood.
It’s crucial to get in touch with your doctor right away if you see additional bright red blood because it could indicate a more serious illness.
Stools that are dark or tarry may indicate bleeding from the small intestine or stomach, which are located in the upper digestive tract. As the blood travels through the gastrointestinal system, it may get partially digested, leading to a black, sticky, or tar-like appearance. It’s crucial to remember, though, that some meals, such as black liquorice, blueberries, and blood sausage, can also result in dark stools. Activated charcoal, bismuth subsalicylate (found in Pepto-Bismol), and iron supplements may also cause comparable colour changes in the faeces.
When Should You Be Concerned About Blood in Stool?
It’s important to consult a doctor or a gastroenterologist in Thrissur if you experience any of the following:
- More than three weeks of blood in the stool
- Heavy bleeding or the presence of blood clots
- Severe pain, fever, chills, weakness, or episodes of fainting
- Changes in stool shape, size, or color persisting for over three weeks
- No obvious cause such as hemorrhoids or constipation
- A family history of colorectal cancer or polyps
If you notice any of these warning signs, seek prompt evaluation from a rectal bleeding specialist in Hyderabad or the best available gastroenterologist for early diagnosis and treatment.
What Can Cause Blood in Stool?
From small problems like dietary variables, haemorrhoids, or anal fissures to more serious illnesses like gastrointestinal bleeding, infections, or inflammatory bowel diseases, there are many reasons why people get blood in their stool or experience rectal bleeding.
Hemorrhoids:
Enlarged blood vessels called haemorrhoids can develop internally in the lower rectum or externally around the anus. Rectal bleeding is most frequently caused by them, particularly in middle-aged and older adults. Contributing factors include chronic constipation, straining during bowel movements, pregnancy, and extended periods of sitting on the toilet.
Rectal pain, itching, bright red blood, and in rare instances, prolapsed hemorrhoids—where the enlarged veins protrude from the anal canal—are some of the symptoms.
Anal Fissures:
Small tears or cracks in the skin lining the anal canal are known as anal fissures, and they are typically brought on by straining, constipation, or firm faeces. They may also be brought on by anal diseases, diarrhoea, or delivery.
A noticeable skin tag or lump, anal itching, muscular spasms, acute discomfort during bowel movements, and bright red blood—which is frequently observed on toilet paper after wiping—are common symptoms.
Diverticulosis:
Diverticulosis is caused by weak areas in the colon wall that form microscopic pouches called diverticula. Rectal bleeding can occur when the blood vessels in these pouches weaken and bleed over time. Although diverticulosis is quite common, many individuals remain asymptomatic and unaware of its presence.
Colon Polyps:
The lining of the colon, or big intestine, develops growths known as colon polyps. The majority of polyps are not malignant, but if left untreated, some can progressively develop into colorectal cancer.
Polyps often cause no symptoms, but rectal bleeding can sometimes be an early warning sign. If you notice blood in your stool, consult a doctor promptly to rule out or confirm the presence of colon polyps. Early detection of polyps and their removal can significantly reduce the risk of colon cancer.
Gastrointestinal Infections:
Rectal bleeding may result from inflammation and irritation brought on by specific digestive tract infections. For example, an overgrowth of Helicobacter pylori in the stomach can result in bleeding ulcers and black stools. Bright red blood can be a sign of other intestinal bacterial or parasite diseases, which are frequently followed by diarrhoea and cramping in the abdomen.
Inflammatory Bowel Disease (IBD):
IBD, which includes Crohn’s disease and ulcerative colitis, is brought on by an aberrant immune response that results in persistent inflammation of the gastrointestinal tract. This inflammation manifests as abdominal pain, urgency, cramps, diarrhoea, and blood in the stool. IBD often requires long-term medical management to control flare-ups and minimize complications.
Colon Cancer:
Colorectal cancer develops in the colon or rectum and may not always present clear symptoms in its early stages. However, warning signs can include blood in the stool (either bright red or dark), changes in bowel habits, bloating, gas pain, unexplained weight loss, and fatigue. Early detection through screening is key to effective treatment and better outcomes.
Colon Cancer Screening Can Save Lives:
Colonoscopy is widely regarded as the gold standard for colon cancer screening. It not only detects early signs of cancer but also allows for the removal of polyps before they become cancerous. Early-stage cancers found during a colonoscopy can often be successfully treated with surgery. Other screening options include stool-based tests that detect occult blood or abnormal DNA, sometimes combined with sigmoidoscopy for further evaluation.
Diagnosing the Cause of Blood in Stool:
A doctor will start with a physical examination and a thorough discussion of your symptoms in order to identify the reason of your rectal bleeding. Based on the findings, the doctor may recommend one or more of the following diagnostic tests to identify the source of bleeding:
Diagnostic Tests for Blood in Stool
Fecal Occult Blood Test (FOBT) / Fecal Immunochemical Test (FIT): These tests detect hidden (occult) blood in the stool.
Complete Blood Count (CBC): Measures blood levels to assess the extent of blood loss.
Colonoscopy: A flexible tube with a camera (colonoscope) is used to inspect the colon. Any polyps found during the procedure can be removed immediately.
Sigmoidoscopy: Focuses on examining the lower part of the colon, including the sigmoid colon and rectum.
Clotting Time Test: Especially relevant for individuals on blood-thinning medications, this test checks how well the blood is clotting.
Treatment Options for Blood in Stool
The underlying cause of blood in stool determines the course of treatment, which can vary from minor problems like haemorrhoids and anal fissures to more serious illnesses including infections, colon cancer, or inflammatory bowel diseases (IBD). Following a diagnosis, the following courses of treatment might be suggested:
For Minor Conditions (e.g., Piles, Anal Fissures):
In most mild cases, lifestyle changes and home-based treatments are often effective:
Increase Dietary Fiber and Fluid Intake: A fiber-rich diet including fruits, vegetables, whole grains, and plenty of water can help soften stools and promote smooth bowel movements, reducing strain during defecation.
Over-the-Counter Creams or Ointments: Hemorrhoid creams, soothing gels, or medicated wipes can help relieve itching, pain, and inflammation.
Sitz Baths: Sitting in warm water for 10–15 minutes a few times a day can soothe the anal area and speed up healing of fissures or hemorrhoids.
Stool Softeners: This help prevent hard stools and reduce the need to strain during bowel movements.
Laser or Minimally Invasive Surgery: If symptoms persist despite conservative treatment, modern procedures like laser surgery offer a painless and quick solution with faster recovery times.
For Serious Conditions:
When rectal bleeding is caused by more serious medical issues, targeted treatments are required:
Medications:
- Infections of the gastrointestinal system caused by bacteria are treated with antibiotics.
- IBD, including Crohn’s disease and ulcerative colitis, is treated with anti-inflammatory medications.
- Acid-reducing medications help treat bleeding ulcers caused by stomach acid.
Surgical Options:
Removal of large polyps, treatment of severe diverticulitis, or surgical intervention for colon cancer may be necessary.
The removal of polyps during a colonoscopy, known as a polypectomy, can also stop the growth of cancer.
Cancer Treatment:
In cases of colorectal cancer, treatment may involve a combination of surgery, chemotherapy, and radiotherapy, as advised by the oncologist.
Effective management of rectal bleeding and the avoidance of consequences depend on early identification and appropriate treatment.
Conclusion
While occasional blood in the stool may result from minor issues like piles or fissures, persistent or heavy rectal bleeding should never be ignored. Early diagnosis plays a vital role in ruling out serious conditions such as inflammatory bowel disease or colorectal cancer and ensuring timely treatment.
