The influence of ispaghula husk on bowel habit

Frequency of defaecation, faecal form, straining at the start and end of defaecation, feelings of incomplete evacuation of faeces and urgency of defaecation were recorded in 69 healthy volunteers during three distinct 28-day study phases: pre-treatment, treatment with ispaghula husk and post-treatment. During treatment there was a significant increase (P < 0.001) in stool frequency and significant decreases in straining at the start (P < 0.001) and end (P < 0.001) of defaecation and in feelings of incomplete evacuation (P < 0.001). There was evidence of a beneficial residual effect after treatment had stopped. There are indications that ispaghula husk (Fybogel Orange) is of benefit in relieving constipation symptoms in apparently healthy people.
