(HealthDay News) -- Irritable Bowel Syndrome is a collection of symptoms, typically without visible signs of damage or disease in the digestive tract.
People who have family members with IBS are at greater risk themselves, says the National Institutes of Health. Other risk factors include a gastrointestinal infection or a recent stressful event.
Symptoms of IBS may include:
Diarrhea or constipation.
Whitish mucus in the stool.
To diagnose IBS, a doctor will track symptoms over time.
