Constipation is a problem affecting between 12 and 19 % of people within the United States [1] and is described as infrequent defecation and/or difficulty passing stool [2]. This condition is more common in certain groups including women, children, and the elderly [3]. The Rome criteria define functional constipation as including two or more of the following: At least 25 % of defecation involves straining, lumpy or hard stool, sensation of incomplete evacuation, sensation of anorectal obstruction/blockage, or manual maneuvers to facilitate defecation, and there are fewer than three defecations per week [4]. Additionally, loose stool are rarely present without use of laxatives, and there are insufficient criteria for irritable bowel syndrome.
