Background and aim: The main items which are evaluated in a GI disorder or diarrhea] state are; frequency of defecation, stool weight, stool consistency and presence of inflammatory cells in the stool. The aim of this study was to find the normal range of the mentioned variables so that could help to differentiate between healthy persons and patients. Methods: The sample consisted of 1 000 healthy persons among attendants of Shahrekord health centers. After explaining the method, they were requested to collect a 24-48 hours stool specimen in special containers. Carmen was used as beginning marker and activated charcoal used as end of the period marker. The variables of each stool were written down in a questionnaire. The SSPS software was used for analyzing the data by regression and t-test. Results: The mean daily stool weight of the sample was found to be 349±131 gr. On average the frequency of defecation was 1.5 times a day and the intestinal transit time was estimated to be about 12.5 hours. Stool weight had a significant correlation with gender, body weight, age, amount of bread consumed daily and defecation frequency (P<0.005). Conclusion: Based on the results the diarrheal criteria for Iranian population are different from what mentioned in the reference books for western population. This is significant, especially for stool weight. More studies are necessary to find out definitive criteria of diarrhea for Iranian population.
