INTRODUCTION : Normal bowel habits vary considerably from person to person. Anything from 3 times a day to 3 times a week can be quite normal. The colon and rectum plays an important role in regulating the bowel frequency, its movement and in maintaining its consistency. AIM OF THE STUDY : 1. To define the bowel frequency / habits in the general population of South India and to determine the prevalence of Irritable bowel disorder and its subtypes in the population. 2. To identify prospectively the bowel pattern in irritable bowel syndrome in gastroenterology referral practice at a tertiary center. 3. To propose guidelines for diagnosis of IBS in south Indian patients. MATERIALS AND METHODS : The study was divided into two parts: (A) Study of normal bowel pattern in healthy south Indian population: The study group consisted of healthy population belonging to either sex and age between 15 yrs and above and less than 70 yrs and who were residents of North Chennai for minimum period of one year. Extremes of age were excluded because of possibility of unsettled bowel habits in younger age and physiological problems of aging and poor recall in the elderly. (B) Prospective study of bowel pattern in IBS : Individuals amongst the healthy population in whom the bowel pattern was considered as abnormal, and in those who had an alteration in bowel symptoms for a period of more than 3 months with or without abdominal pain probably had an IBS and were considered for further evaluation. CONCLUSION : Large population based studies are likely to provide a definite information on the normal bowel habit of southern Indian population of Tamil Nadu. There may be a need to redefine the existing Rome II criteria for the southern Indian population of Tamil Nadu, since pain is not a dominant feature of IBS in this population. The recommendations for diagnosis of IBS amongst the southern Indian population of Tamil Nadu requires the incorporation of the following variables. a. Alteration of bowel pattern in terms of frequency / consistency, b. Duration of illness of more than or equal to 6 months, c. Pain should not be a major criteria for diagnosing IBS, rather it should be only a supportive feature, d. Criteria for subtypes: i. Diarrhoea predominant-IBS: Stool frequency > 3 per day, loose stool, with or without abdominal pain, presence of urgency and mucus in stool, ii. Constipation predominant -IBS: stool frequency of less than 3 per week, hard stool, associated with abdominal bloat, straining and incomplete evacuation during the passage of stool.
