Facts About IBS

Irritable bowel syndrome (IBS) is a disorder characterized by abdominal pain or discomfort, and altered bowel habit (chronic or recurrent diarrhea, constipation, or both – either mixed or in alternation).

• IBS affects between 25 and 45 million people in the United States (10 to 15% of the population). Approximately 60 to 65% of IBS sufferers are female; 35 to 40% are male. IBS affects people of all ages, even children. 
• The exact cause of IBS is not known. Symptoms appear to result from a disturbance in the interaction between the gut, brain, and nervous system that alters regulation of bowel motor or sensory function. IBS is not caused by stress. However, because of the connection between the brain and the gut, symptoms can be exacerbated or triggered by stress.
• The impact of IBS can range from mild inconvenience to severe debilitation, controlling many aspects of one's emotional, social and professional life. Those with moderate to severe cases, affecting an estimated 10 to 15 million people, must struggle to overcome symptoms that often impair their physical, emotional, economic, educational and social well-being.
• IBS is unpredictable. Symptoms vary and are sometimes contradictory, such as diarrhea alternating with constipation. Chronic and recurrent symptoms can disrupt personal and professional activities, upset emotional well-being and limit individual potential.
• Treatments are available for IBS to help manage symptoms. However, research is needed to provide greater relief and more treatment options.
• Although IBS is very common in the general population, few seek medical care for their symptoms. On average, patients report it takes more than three years from onset to diagnosis, and see nearly three healthcare professionals before their condition is diagnosed as IBS.
• Approximately 20 to 40% of all visits to gastroenterologists are due to IBS symptoms.
• For those with IBS an additional burden comes from living in a society where the word "bowel" may scarcely be spoken. Individuals are left to cope with multiple symptoms that affect every aspect of their lives while those around them may be unaware of the true impact, or even the existence, of the disorder.
• IBS can only be diagnosed by a medical professional.
