Why do i never feel fully evacuated after a bowel movement and how can i help reduce and relive the feeling?

Could be several : Things, but most likeley you are having trouble cleaning up with smeary pasty stools and then returning to have another bowel movement within a few hours. This is being short of fluids by about 40-50 ounces. Remember caffeine in all forms dehydrates. You need 80-100 ounces of caffeine free/alcohol free fluid daily. Might also be internal hemorrhoids giving the sense of incomplete evacuation.
