The seven types of<unk>  are: *Type 1: Separate hard lumps, like nuts (difficult to pass and can be black) *Type 2: Sausage-shaped, but lumpy *Type 3: Like a sausage but with cracks on its surface (can be black) *Type 4: Like a sausage or snake, smooth and soft (average<unk>  *Type 5: Soft blobs with clear cut edges *Type 6: Fluffy pieces with ragged edges, a mushy<unk>  (diarrhoea) *Type 7: Watery, no solid pieces, entirely liquid (diarrhoea) Types 1 and 2 indicate constipation, with 3 and 4 being the ideal<unk> s as they are easy to defecate while not containing excess liquid, 5 indicating lack of dietary fiber, and 6 and 7 indicate diarrhoea. In the initial study, in the population examined in this<unk> , the type 1 and 2<unk> s were more prevalent in females, while the type 5 and 6<unk> s were more prevalent in males; furthermore, 80% of subjects who reported rectal tenesmus (sensation of incomplete defecation) had type 7. These and other data have allowed the<unk>  to be validated. The<unk>  is also very sensitive to changes in intestinal transit time caused by medications, such as antidiarrhoeal loperamide, senna, or anthraquinone with laxative effect.
