Symptoms and Causes of Irritable Bowel Syndrome

  • Abdominal Pain and Cramping 

  • Changes in Bowel Habits 

  • Diarrhea 

  • Constipation 

  • Mixed Symptoms: alternating between diarrhea and constipation 

  • Bloating and Gas

Causes of IBS: The exact cause of IBS is unknown, but several factors are thought to contribute: 

  • Abnormal Gut Motility: Irregular contractions in the intestinal muscles can cause diarrhea or constipation. 

  • Gut-Brain Interaction: Miscommunication between the brain and the gut may lead to heightened sensitivity or abnormal gut function.

  • Intestinal Inflammation: Some IBS patients have low-grade inflammation in the gut.

  • Gut Microbiota Changes: Alterations in the composition of gut bacteria can contribute to symptoms. 

  • Food Sensitivities: Certain foods (e.g., high-FODMAP foods) may trigger symptoms. 

  • Stress and Anxiety: Emotional stress and mental health issues can exacerbate IBS symptoms. 

  • Post-Infectious IBS: After a severe bout of gastroenteritis, some people develop IBS symptoms.
