Differential Diagnosis for Mucous in Stools

Single Most Likely Diagnosis

  • Irritable Bowel Syndrome (IBS): This condition is characterized by a combination of abdominal pain, bloating, and changes in bowel movements, which can include the presence of mucous in stools. It's a common condition and often presents with a range of gastrointestinal symptoms.

Other Likely Diagnoses

  • Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease and ulcerative colitis can cause inflammation in the digestive tract, leading to symptoms including mucous in stools, diarrhea, and abdominal pain.
  • Infectious Gastroenteritis: Viral or bacterial infections can cause inflammation of the stomach and intestines, resulting in symptoms such as diarrhea, which may contain mucous, vomiting, and abdominal cramps.
  • Diverticulitis: Inflammation of the diverticula in the wall of the colon can lead to symptoms including changes in bowel habits, which may include the presence of mucous in stools.

Do Not Miss Diagnoses

  • Colorectal Cancer: Although less common, colorectal cancer can present with changes in bowel habits, including the presence of mucous in stools. Early detection is crucial for effective treatment.
  • Intussusception: A condition where a part of the intestine slides into an adjacent part, potentially cutting off blood supply. It's more common in children but can occur in adults, presenting with abdominal pain, vomiting, and stools that may contain mucous and blood.
  • Appendicitis: Inflammation of the appendix can cause severe abdominal pain, fever, and changes in bowel habits. While not typically the first symptom, mucous in stools could be present in some cases.

Rare Diagnoses

  • Lymphogranuloma Venereum (LGV): A sexually transmitted infection that can cause proctitis, leading to symptoms including mucous discharge and diarrhea.
  • Amyloidosis: A condition characterized by the deposition of amyloid proteins in various tissues, including the gastrointestinal tract, which can lead to diarrhea and potentially mucous in stools.
