Can IBS Cause Blood in Stool?

Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and changes in bowel habits, including diarrhea and constipation. However, the presence of blood in stool is not typically associated with IBS and may indicate other underlying conditions.

IBS Symptoms and Diagnosis

IBS is primarily diagnosed based on clinical symptoms, which include abdominal pain related to defecation and changes in stool form or frequency . While IBS can cause significant discomfort and impact quality of life, it does not cause permanent damage to the intestines or lead to serious complications like bleeding .

Differentiating IBS from IBD

Inflammatory Bowel Disease (IBD), which includes Crohn's disease and ulcerative colitis, can present with symptoms similar to IBS, such as abdominal pain and diarrhea. However, IBD is a more severe condition that can cause serious complications, including blood in the stool 26. Faecal calprotectin testing is a useful tool to distinguish between IBS and IBD, as elevated levels of calprotectin are indicative of inflammation seen in IBD but not in IBS .

Blood in Stool: A Red Flag

The presence of blood in stool is a significant red flag that warrants further investigation. While IBS itself does not cause blood in the stool, other conditions such as IBD, infections, or colorectal cancer can . For instance, patients with IBD often present with bloody stools, especially in cases of ulcerative colitis 13. Therefore, if a patient with suspected IBS reports blood in their stool, it is crucial to conduct further diagnostic tests, including colonoscopy, to rule out IBD or other serious conditions .

Conclusion

In summary, IBS does not cause blood in the stool. The presence of blood in stool should prompt healthcare providers to investigate other potential causes, such as IBD or colorectal cancer. Accurate diagnosis is essential for appropriate management and treatment of the underlying condition.
