poorer bowel preparation, bleeding hemorrhoids
CONTRACTION, DISEASES, BLEEDING HEMORRHOIDS
Colonoscopy is a great tool for assessing large intestine and rectum abnormalities. It can be used for evaluating many GI diseases such as bleeding hemorrhoids [Bowel preparation before colonoscopy is essential and determines the imaging quality [There are some factors which can determine the quality of bowel preparation including age [Several items can lead to better preparation, including following instructions precisely [In this study, although there was not a significant correlation between walking and bowel cleansing in the intervention and control groups, individuals with more than 6900 steps had significantly higher bowel cleansing scores (Fig. 
Summary of study setting and resultsIn our study, younger individuals had better bowel preparation (Fig. In addition, in our study, smoking was another risk factor for poorer bowel preparation (Fig. Several mechanisms can justify the positive coloration between mild walking on colon cleansing before colonoscopy. One mechanism can be related to GI tract motility and secretion. GI tract movement is a complicated process resulting from interaction and coordination between multiple cell types like enteric neurons, interstitial cells of Cajal (ICC) and smooth muscle cells, which are located in the tunica vascularis layer. Throughout a process called excitation–contraction coupling, the coordinated contraction of smooth muscle cells leads to GI motility [Our study had some limitations. First, one expert gastroenterologist determined the BBPS. For more accurate data, we highly recommend future studies to assess BBPS by two gastroenterologists. Second, we assessed taken footsteps by a smart band which may not be accurate. We could not assess whether participants wore the band all the time before the colonoscopy. Also, we assessed the footsteps taken by individuals. We did not assess the quality of walking. We could not assess whether participants had mild exercise or moderate or severe.
