• →Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
• →Family history and risk factors increase the probability that vague symptoms represent early Irritable Bowel Syndrome (IBS)
• →Screening programmes are designed specifically to detect Irritable Bowel Syndrome (IBS) before symptoms appear
