What Causes Irritable Bowel Syndrome?

(HealthDay News) -- Irritable bowel syndrome (IBS) may be characterized by symptoms including abdominal discomfort, diarrhea, gas, constipation and bloating.

The Mayo Clinic says these factors may trigger IBS symptoms:

• Certain foods, particularly dairy, chocolate, cabbage, cauliflower, beans, fruit, broccoli, high-fat foods, alcohol and carbonated beverages.
• Emotional stress can worsen IBS symptoms, but may not cause them.
• Changes in hormone levels, such as during menstruation.
• Conditions such as gastroenteritis, or excess bacteria in the gut.
