Here's a different way of looking at a disease. It is the most commonly diagnosed gastrointestinal condition, and direct and indirect costs of this disease can be up to $30 billion dollars a year. This is probably because it is the second highest cause of work absenteeism (behind the common cold). The prevalence in North America is approximately 10 to 15%, yet only 15% of patients seek medical attention. Young patients and women are more likely to have it; there is a 2:1 female to male predominance. This disease makes up 25-50% of referrals to gastroenterologists.
