Occasional holding of feces for a short period of time is generally not harmful, but frequent or prolonged holding of feces may cause constipation, intestinal polyps and other hazards. 1. Constipation: Holding stools for a long time will easily lead to the occurrence of fecal dryness, accumulation and coarsening of feces, and constipation symptoms such as difficulty in defecation will easily occur when defecation occurs. In addition, the stool in the rectum stays too long will continue to stimulate the rectal mucosal receptors, resulting in reduced sensitivity, which can lead to weakening of defecation reflexes, the formation of outlet obstruction type of constipation. 2. Intestinal polyps: in the intestinal tract of the stool due to the act of holding back the stool for too long, the formation of dry feces, can cause continuous stimulation of the intestinal mucosa, leading to the formation of intestinal polyps. There may be other hazards of holding stools, and you can consult your physician for more information.
