Narrow stools

Cause The final shape and narrowness of your motions will depend on how soft they are and how much your anal sphincter muscle relaxes when the stool passes through - it is probably never due to any narrowing higher in the bowel and if you have no other change in bowel habit nor any other symptoms it will be of little significance

 If you do have other changes in your bowel habit then try the ‘Symptom Checker’ to see if you need to see your GP.
