What is a common characteristic of a sigmoid colostomy?

A sigmoid colostomy is typically located in the lower part of the colon and often results in the production of firmer stool compared to other types of colostomies. This is mainly due to the degree of water absorption that occurs in the sigmoid colon, which is the part closest to the rectum. Because the stool has more time to be processed and solidified as it moves through this section of the colon, individuals with a sigmoid colostomy are likely to experience more formed stools.

In contrast, colostomies located in the ascending or transverse sections of the colon may produce looser or more liquid stools because they do not have the same amount of time for absorption. Therefore, the characteristic of producing a firm stool is representative of the normal function of a sigmoid colostomy.
